The medical techniques keeping Team GB healthy during the Olympic Games
The medical techniques keeping Team GB healthy during the Olympic Games
There was a time when you could count the number of British gold medallists on the fingers of one hand. Back in the 1960s and 1970s, winning an Olympics event made you a household name overnight.
Anne Packer, Lynn Davies, Mary Peters, David Hemery, Anita Lonsbrough, – to name a few of the few – were feted across the land to pulling off the seemingly impossible – beating the world, usually in track and field or the swimming pool.
But all that has changed.
London 2012 (29 gold medals); Rio de Janeiro 2016 (27 gold); Tokyo 2020 but actually in 2021 (22 gold).
Time was when most Olympics hopefuls were fanatical amateurs, prepared to turn out on some bleak and chilly track, strip down to their shorts and practise their sport in front of an equally dedicated but minority audience.
Not any more. The British medals haul, however you measure it, is also top of the tree on an international basis. A country of fewer than 70 million people typically comes in the top three or four on the planet behind only the likes of such giants such as the USA and China. We even beat the Australians – on a regular basis.
This has not happened by accident.
Obviously, a huge amount of credit must go to the athletes themselves and their coaches. Their talent and dedication will be fully on display in Paris this week when the Games return to France for the first time in exactly 100 years.
But there is much more to it than that. Team GB has revolutionised British Olympics in recent years. The team numbers more than 300 and for only the second time in our history, there will be more women (172) than male (155) competitors.
Professional coaches, physios, nutritionists, and mind game experts will abound.
The Greatest Show on Earth will dominate our TV screens, social media, press and national conversation for a fortnight (and more).
These are some of the reasons why Randox, Europe’s biggest diagnostic company, is sponsoring Team GB. We love supporting the athletes behind mega sporting events (The Grand National, for instance) and it does not come any more mega than Paris 2024.
We were there the last time – Tokyo 2020 – but in challenging circumstances. Tokyo 2020 actually took place in 2021, postponed for a year because of the Covid pandemic.The glittering contests were performed in front of empty stadiums and sports halls after the Olympic authorities, understandably anxious to avert a super-spreader car crash, prohibited spectators.
Founded in 1982, Randox conducted more than 27 million Covid tests in the UK and offered support to Team GB three years ago for a very specific and vital purpose – to help stop the spread of Covid among the athletes and their support teams. It worked. Despite the fears of the Olympic authorities, the plethora of measures taken to safeguard contestants, meant that only one athlete fell sick and was unable to compete.
Not so this time. 15 million people, two million from abroad, are expected to swamp the French capital over late July and early August.
Our Vivalytic diagnostic machine, used in Tokyo to test all our athletes for Covid, will be in action again. But this time, we will be casting the net far wider, checking for a range of respiratory infections that can lay contestants low.
Our aim, along with the teams of experts assisting our athletes is simple – to ensure that Team GB is in peak physical and mental condition as they get to the starting line.
We have also been working closely with our brand ambassadors to ensure that they are perfectly placed to perform to their utmost in Paris. All of them have undertaken our Everyman and Everywoman diagnostic health testing packages at one of our health clinics, to measure their condition as they prepare for Paris.
As one star, Duncan Scott, our most decorated Olympic swimmer, put it: “If it makes one per cent difference, it’s 100 per cent worth it.
“It excited me that it was essentially a head-to-toe MOT and there’s areas I’ve never really had much data, on but also last year I had an IgE (antibody) deficiency impacting my immune system which made training so inconsistent as some days I felt sluggish.
“This year has been much more consistent after picking up on it which makes me wish I had something like this, as if I did this last year or 24 months ago, it’d have been ideal going in unknown and then picking up on it as a risk rather than me getting frustrated and being ill.”
Top sprinter Daryll Neita, a multiple medal winner, took the Everywoman test, “the most in-depth testing I’ve ever had.”
Her verdict points to the confidence boost of knowing you are in peak condition physically: “Although I’ve not had any recent health concerns, it’s amazing that the Everywoman test discovers things that could help my performance.
“Whether it’s how I recover or deficiencies, but also our sport is about marginal gains, centimetres, millimetres, the finest of margins and through tests like this, it lets you stay on-top of your health, helping you achieve optimal performance or even a mental boost that you’re healthy.”
Team GB’s Chief Medical Officer Niall Elliott, said that Randox was helping in three critical areas of health testing for athletes – iron metabolism, vitamin D levels – critical to the immune system and muscle power – and glucose or energy levels. “It is a fascinating journey, the testing we can do.”
This must be the best prepared – and the most safeguarded – Team GB ever to leave our shores.
As devotees of the wonderful film, Chariots of Fire, will know, they have much to live up to. Back in the 1924 Paris Olympics, Harold Abrahams in the 100 metres and Eric Liddell in the 400 metres both emerged triumphant. On top of their legendary feats, Britain secured seven more gold medals.
We can only hope and pray that our champions, bolstered by the latest in sports science, can achieve even greater heights.

Active vs Total Vitamin B12
Total vs Active B12
Vitamin B12, or cobalamin, is a vital water-soluble vitamin that plays an essential role in myelination initiation and development, cellular energy and fatty acid metabolism. It is a cofactor for enzymes methionine synthase and L-methyl-malonyl-coenzyme A mutase and, in addition to folate, is essential for DNA and protein synthesis. In the UK, up to 6% of adults under 60 have been diagnosed with Vitamin B12 deficiency and figures are much higher in elderly populations1. Additionally, these data do not consider the high rates of missed diagnosis associated with B12 deficiency, which some reports claim to be as high as 26%2. New guidance from the National Institute of Health and Care Excellence (NICE) advise that Active vitamin B12 testing is recommended for some groups of patients. In this article, we’ll look at this essential vitamin, B12 deficiency and the associated complications, compare the biomarkers used to diagnose B12 deficiency, and finally, present the new Acusera Active B12 Control.
Aetiology
Vitamin B12 deficiency can arise due to dietary insufficiency, malabsorption resulting from damage to the small intestine, often caused by conditions like Coeliac disease or Crohn’s disease, or via pernicious anaemia – an autoimmune condition which results in an inability to absorb vitamin B12.
It is a common problem in the elderly population – bodily stores of vitamin B12 can take up to 20 years to become depleted, meaning complications have often already begun before diagnosis occurs. The most common source of vitamin B12 comes from dietary intake of animal products therefore vegetarian dietary requirements are considered a considerable risk factor for vitamin B12 deficiency.
Pathophysiology and Complications
Vitamin B12 deficiency significantly impacts health, affecting various bodily functions, potentially leading to a range of complications. Megaloblastic anaemia is a common complication associated with vitamin B12 deficiency and is characterised by the presence of large red blood cell precursors (megaloblasts) in the bone marrow3. The lack of vitamin B12 results in impaired DNA synthesis and an inhibition of nuclear division. However, cytoplasmic maturation is less effected. This results in asynchronous maturation of the nucleus and cytoplasm in erythrocytes and causes the synthesis of abnormally large megaloblasts. This causes the cessation of DNA synthesis and DNA replication errors, culminating in apoptotic cell death. Common symptoms of megaloblastic anaemia include weakness, shortness of breath, palpitations, tachycardia, Hunter glossitis or splenomegaly3.
Pernicious anaemia is a condition commonly associated by vitamin B12 deficiency. Pernicious anaemia is an autoimmune disorder which affects the gastric mucosa resulting in impaired absorption of vitamin B12. Common symptoms of pernicious anaemia include glossitis, hair loss, dry skin, memory loss, poor concentration, poor sleep, confusion and dizziness, shortness of breath, Diarrhoea, indigestion, loss of appetite, mood swings and suicidal thoughts.
Neurological issues may also arise, including numbness, mobility loss, and memory issues, and in some cases, depression4. Additionally, B12 deficiency is linked to increased risks of cardiovascular events5, infertility6, and autoimmune diseases like multiple sclerosis7 and lupus8. In children, vitamin B12 deficiency can manifest as failure of brain and overall growth and development, developmental regression, hypotonia, lethargy, hyperirritability, or coma9.
Active B12 as a marker of Deficiency
There are several markers of vitamin B12 deficiency. The most used in clinical practice are total vitamin B12, homocysteine, methylmalonic acid (MMA), and Holotranscobalamin (HoloTC) – also known as Active B12. HoloTC accounts for between 10-30% of total B12 and is the metabolically active form of vitamin B12.
When compared with total B12 quantification, HoloTC measurement has been shown to be a more sensitive and specific biomarker of B12 deficiency, particularly at borderline clinical levels10, in various cohorts11,12 including those on vegan diets13 – a known risk factor for B12 deficiency. Furthermore, HoloTC was shown to provide the higher diagnostic accuracy in clinical and subclinical B12 deficiency versus Total B12, MMA and homocysteine with significantly higher accuracy in women over 5011 – a population at high risk of B12 deficiency.
In response to the mounting evidence of the superior utility of HoloTC quantification, the National Institute for Health and Care Excellence (NICE) have produced new guidelines recommending either total B12 or HoloTC for the initial testing of suspected vitamin B12 deficiency. These guidelines specify the use of active B12 during pregnancy and suggest that active B12 might provide a more specific assessment in certain clinical contexts.
Acusera Active B12 Control

Bordetella Detection & Species Identification Educational Guide
Bordetella Detection and Species Identification with the Vivalytic
Cases of Bordetella infections are rising across Europe. Bordetella species are responsible for whooping cough, or pertussis, which literally means violet cough. Vaccine deployment in the 1940s saw a reduction in the morbidity and mortality associated with these infections and now, healthy adults can be expected to make a full recovery. However, vulnerable populations, such as children, the elderly and the immunocompromised, have been shown to be at increased risk of more severe and long-lasting side effects, including increased risk of mortality.
Traditional methods of identifying Bordetella infections take the form of culture, which can take up to 7 days due to the fastidious and slow-growing nature of these bacteria and provide limited sensitivity1,2. To provide a faster and more sensitive method for the identification of whooping cough pathogens, Randox, in partnership with Bosch, are proud to introduce the Vivalytic Bordetella Cartridge. This real-time PCR assay allows detection of B. pertussis, B. parapertussis and B. holmesii on the Vivalytic system, a universal, fully automated, cartridge-based platform enabling high-plex and low-plex testing, providing an all-in-one solution for molecular diagnostics.
To help you understand the implications of Bordetella infections and those of the Vivalytic system, we have produced a new educational guide, covering the Bordetella species responsible for whooping cough; the pathophysiology and complications associated with these infections; the Vivalytic platform and the benefits it can bring to your laboratory; and finally, a summary of findings presented at ESCMID 2024 in which the Vivalytic Bordetella cartridge showed excellent results. Here, we present this educational guide and a summary of its contents. You can download this guide for free by clicking the download link below.
The Scale of the Bordetella Problem
The rates of positive identification of Bordetella infection are increasing throughout Europe. In England, between January and March 2024, there were 2793 laboratory confirmed cases of whooping cough causing the deaths of 5 infants, compared with a total of 858 cases in 20233. A rudimentary projection model estimates that without intervention, whooping cough cases in the England could total over 15,000 cases by the end of 2024. Rising cases are not isolated to the UK – increased rates of diagnosis have also been reported in Denmark, Spain, and Croatia4. Increased numbers of infections illustrate the need for novel and rapid diagnostics to identify those who have been infected and help reduce the transmission of these bacteria.
Bordetella genus
Bacteria of the Bordetella genus are gram-negative coccobacilli5 which are important pathogens in human medicine as they colonise the respiratory tract leading to a range of pulmonary and bronchial infections6. There are 3 main species associated with whooping cough: of B. pertussis, B. parapertussis (Classical Bordetella) and B. holmesii (pertussis-like disease pathogen).
Pertussis is caused by Classical Bordetella: B. pertussis and B. parapertussis. Despite widespread vaccination cases are rising, partially due to waning immunity. Pertussis is highly contagious and particularly dangerous for infants, who account for most pertussis-related deaths. The disease progresses through three phases: catarrhal (cold-like symptoms), paroxysmal (severe coughing fits), and convalescent (persistent cough). Classical Bordetella species share over 98% DNA sequence similarity and share many crucial virulence factors like toxins adenylate cyclase toxin (ACT), pertussis toxin (PXT), and dermonecrotic toxin5 yet there are variations in potential hosts and disease. For example, B. pertussis is an exclusively human pathogen, whereas B. parapertussis can infect both humans and sheep6.
Bordetella holmesii causes pertussis-like symptoms but is ofen less severe. Unlike classical Bordetella, B. holmesii can cause bacteraemia, especially in immunocompromised individuals. Accurate diagnosis of B. holmesii remains challenging due to its similarities with other Bordetella species.
Whooping cough can lead to complications such as pneumonia, which may develop if fever persists beyond the catarrhal phase2. CNS complications like seizures and encephalopathy occur in less than 2% of cases, often due to hypoxia, hypoglycaemia, toxins, or secondary infections2. Bordetella toxins, especially PXT, increase histamine sensitivity and insulin secretion. Infants are especially at risk of bradycardia, hypotension, and cardiac arrest.
Vivalytic Bordetella Cartridge
To enhance the detection and species identification of Bordetella, Randox introduces the Vivalytic Bordetella cartridge. This user-friendly assay is designed to detect B. pertussis, B. parapertussis, and B. holmesii from a single nasopharyngeal swab or aspirate sample. Utilising Real-time PCR, it enables rapid and accurate detection up to four weeks after symptom onset, differentiating between human pathogenic Bordetella species. With a time to result of just 47 minutes, this assay is invaluable for patient diagnosis and the containment of Bordetella, helping to reduce aerogenic transmission.
Summary of Benefits:
- Sample Volume – 300μl.
- Sample Type – Nasopharyngeal swab sample or aspirates.
- Real-time PCR detection.
- Time to result – ~47 minutes.
- Detection of B. pertussis, B. parapertussis, and B. holmesii.
Rapid and Accurate Detection of Whooping Cough in Clinical Samples
Zimmerman, 2024
At the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) 2024 congress, the Vivalytic Bordetella array showed excellent performance, with a 97.7% concordance and a 97.9% positive percent agreement (PPA) with the reference method.7 It accurately identified all additional positive samples and maintained over 98% PPA across spiked samples, even at low levels. The system’s invalid result rate was notably low at 0.6%, compared to 2.9% with the BioGX assay7.
The conclusions drawn from this investigation are as follows:
- The Vivalytic Bordetella cartridge provided excellent concordance with a sensitive reference method and delivered fast and accurate results.
- This assay is ideal for both hospital laboratories and outpatient settings, thanks to its user-friendly design and quick turnaround times.
- Early identification of infected patients will aid in preventing the spread of re-emerging whooping cough epidemics.
Conclusion
As Bordetella infections rise across Europe, rapid and accurate detection is crucial. The Vivalytic Bordetella Cartridge offers a fast, reliable solution, identifying B. pertussis, B. parapertussis, and B. holmesii with high accuracy in just 47 minutes. This advanced diagnostic tool can help reduce transmission and manage whooping cough effectively.

Combating Gastroenteritis – Advanced Diagnostic Techniques for Effective Management
Gastroenteritis, often referred to as stomach flu or a stomach bug, affects millions globally each year with symptoms such as diarrhoea, vomiting, abdominal pain, and fever. It is primarily caused by viral and bacterial infections, with rotavirus, norovirus, and Clostridium difficile being the main culprits.
At Randox, we’re dedicated to improving healthcare worldwide. That’s why we’ve produced an educational guide on gastroenteritis and the latest advancements in diagnostic techniques, including a range of novel gastroenteritis test for the Vivalytic POCT system. In this blog, we’ll look at a few of the key points raised in our latest educational guide. You can download this educational guide by clicking the below.
Why Gastroenteritis Matters
Gastroenteritis can lead to severe dehydration, especially in vulnerable groups like children and the elderly. It spreads mainly through the faecal-oral route, which includes consuming contaminated food and water. Prompt and accurate diagnosis is crucial for effective management.
Key Pathogens
Rotavirus
Rotavirus is a major cause of severe gastroenteritis in children. Highly contagious, it leads to rapid dehydration, making rehydration and supportive care essential. Vaccines like Rotarix and RotaTeq are effective in preventing infections.
Norovirus
Norovirus is responsible for most viral gastroenteritis outbreaks. Extremely contagious, it spreads quickly through direct contact and contaminated food. Symptoms include sudden vomiting and diarrhoea, often leading to dehydration. While there’s no specific treatment, staying hydrated is key.
Clostridium difficile
Clostridium difficile, or C. diff, is a leading cause of antibiotic-associated diarrhoea, particularly in healthcare settings. It produces toxins that cause inflammation and damage to the colon, requiring targeted antibiotic treatment for severe cases.
Advanced Diagnostics: The Vivalytic System
Accurate and timely detection of gastroenteritis pathogens is crucial for effective patient management. The Vivalytic Point of Care Testing (POCT) system, developed by Bosch Healthcare Solutions and Randox Laboratories, offers rapid and reliable diagnostics. This system helps healthcare professionals make quicker decisions, improving patient outcomes.
The Vivalytic Gastroenteritis Panels
The Vivalytic panels detailed in our guide include tests for rotavirus, norovirus, and Clostridium difficile. These panels utilise advanced molecular techniques to provide quick and accurate results, helping to streamline the diagnosis process and enhance patient care. By using these panels, healthcare providers can efficiently identify the specific pathogens responsible for gastroenteritis, allowing for targeted treatment and improved patient outcomes.
Features of the Vivalytic System
The Vivalytic system is user-friendly and efficient. It supports both High-Plex and Low-Plex testing, allowing for the simultaneous detection of multiple pathogens from a single sample. This versatility makes it an invaluable tool for healthcare professionals.
Conclusion
Gastroenteritis, caused by pathogens like rotavirus, norovirus, and Clostridium difficile, presents significant health challenges. Advanced diagnostic technologies, such as the Vivalytic system, are crucial in managing and controlling this condition.

Randox named as Company of the year
Randox tops the charts in Belfast Telegraph Top 100 Companies
Randox is the largest blood-sciences healthcare diagnostics company from the UK and Ireland. Established in 1982 by managing director Dr Peter FitzGerald, Randox manufactures more than four billion tests per year and has a global sales and distribution network supplying product to 145 countries. Randox estimates more than 400 million people, around 5% of the world’s population, receive a diagnosis involving Randox products each year. Key facilities are located at multiple sites within Northern Ireland, in Co Donegal, in West Virginia in the United States and in Bengaluru, India.
As a privately-owned company Randox invests heavily in research and development, committing up to 25% of turnover for the development of new diagnostic products. Recent testing developments include: Type 1 Diabetes Genetic Risk Score; an advanced PSA test to improve the predictive potential of PSA alone for prostate cancer; predictive bladder cancer testing panels; risk assessment for post operative acute kidney injury and chronic kidney disease; and wide-ranging quality control and external quality assurance capabilities to ensure the accuracy and reliability of laboratory results.
Randox’s innovative approach to R&D has allowed the development of allied capabilities outside the immediate world of human healthcare, including leading testing capabilities in the veterinary field, for toxicology and for the detection of harmful drug residues and pathogens in food.
Research and development programmes are not limited to the development of tests, but also includes the advanced analyser systems to process samples efficiently. This requires integral, advanced capabilities in electrical and mechanical engineering, optics, robotics and software engineering.
Over £350m of investment has supported the development of a unique testing system to allow multiple tests to be run simultaneously on a single sample – the Randox Biochip. This 9mm x 9mm platform, which allows up to 49 tests to be run simultaneously, greatly increases the diagnostic power available to clinicians to enable earlier, more accurate diagnosis and improved patient outcomes. Initially focused on proteomics, Randox has also greatly increased its genetic testing capabilities to increase predictive capabilities.
In order to support the model of diagnostically-led healthcare, Randox has developed the Randox Health brand, to provide public access to comprehensive testing. The aim is to empower the consumer and to enable a preventative approach to healthcare – rather than rely upon the treatment of illness. Well over 20 clinics are now available across the UK and Ireland, including in partnership within John Lewis stores.
At the outset of the Covid-19 pandemic Randox was ideally placed to support the UK’s requirement for a national Covid-19 testing programme. By mid-February 2020 Randox were amongst the global frontrunners in developing a Covid-19 test and had developed home sample collection and reporting capabilities. The company was engaged by Government from mid-March 2020 to support the UK’s national testing programme – at that time the complete NHS testing capability for Covid-19 was reported as 2,400 tests per day.
Rising to meet this unprecedented national demand markedly increased company turnover and profits. A post-pandemic assessment by consultants OCO Global concluded that Randox’s activities during the pandemic averted over 3,100 deaths, prevented 14,100 hospitalizations and enabled a £8.3bn contribution to the UK’s GDP.
Exiting from the pandemic and reverting to sector norms with a strong balance sheet, Randox is investing heavily in upgrading the company’s infrastructure and R&D programmes. Randox is also investing significant resources in expanding the business-to-consumer diagnostic offer under the Randox Health brand – with clinics in the UK and Ireland, and US.
Noting the pressures upon all healthcare systems, and a need to transition from ‘illness management’ to more sustainable ‘prevention’ models, Randox is investing heavily for the future. Its aim is to ensure it is well positioned to support and enable healthcare transformation through improved diagnostics, to both increase system efficiencies and improve patient outcomes.
Joe Kennedy III, US special envoy for economic affairs visited Randox Science Park in Antrim last week to listen for presentations on Randox Laboratories MultiSTAT and RABTA analysers. He wrote in a foreword to the Belfast Telegraph article, “I congratulate everyone who has contributed to the success of Northern Ireland’s Top 100 Companies. “From globally-recognised brands to indigenous firms, each company reflects the wide diversity of employers who generate prosperity and opportunity right across Northern Ireland.”
Randox managing director Dr. Peter FitzGerald said it welcomed the accolade of being named number one company.
“These results reflect the skills, commitment and agility of our people, and the capability of our unique technologies.
“As a team we were also able to call upon 40 years of diagnostic experience to meet the exceptional demands of Covid-19, while simultaneously supporting our established global customer base of healthcare laboratories. Crucial to this was our long term commitment to research and development which has always been a cornerstone of our business philosophy.
“Randox is committed to enhancing healthcare through more sensitive and accurate diagnostics to enable the prevention of disease and improve healthcare outcomes, whilst reducing the burden on healthcare services.
“Our profits will continue to be directed towards enabling our infrastructure and research and development, as well as accelerating better healthcare models and improving direct public access through our Randox Health clinics. Our ambition is to enable better health outcomes for all and we are committed to that goal.”
Dementia Action Week 2024
Dementia Action Week 2024 (13th – 20th May)
The term Dementia describes the different brain disorders that trigger a loss of brain function. These conditions are all usually progressive and eventually severe. Alzheimer’s Disease is the most common type of dementia, affecting 62 per cent of all those diagnosed.
Dementia is a general term for loss of memory, language, problem-solving and other thinking abilities that are severe enough to interfere with daily life. Common symptoms include memory loss, confusion, and speech problems. Early warning signs may also include finding it difficult to follow conversations, or programs on TV, forgetting names of friends, or everyday objects and feeling confused even in a familiar environment.
Mainly affecting older people, after the age of 65, the likelihood of developing dementia roughly doubles every five years – however, for some dementia can develop earlier, presenting different issues for the person affected, their carer and their family. There is also a considerable economic cost associated with the disease estimated at £23 billion a year, which is predicted to triple by 2040. This is more than the cost of cancer, heart disease, and stroke.
At Randox, we recognise the importance in diagnosing dementia early. Through our Randox Alzheimer’s Disease Array which can be used for Rapid Identification of Alzheimer’s Disease Risk. Randox’s Alzheimer’s Disease Risk Array can be used for the direct determination of ApoE4 status from plasma, eliminating the need for genetic testing, assisting in clinical research and personalised medicine strategies. At Randox, we believe the importance of measuring ApoE4 protein expression in plasma is the way forward to screen those individuals at increased risk of Alzheimer Disease, as new beta amyloid-targeting therapies for this condition are being expected.
Race Against Dementia have been the partner charity for the Randox Grand National Festival over the past two years, working alongside this charity which was founded by three-times Formula One World Champion, Sir Jackie Stewart, with the aim of funding much needed pioneering research into the prevention and cure of dementia.

Serum Indices – Product Spotlight
Errors can occur at any point in the pre-analytical, analytical, or post-analytical stages of a diagnostic test. It is general practice for errors in the analytical stage to be identified through quality control procedures. However, pre-analytical errors are often treated with less importance than those in later stages of testing. Interference caused by haemolysis, icterus and lipemia (HIL) are common forms of pre-analytical error which affect assay methods, yielding erroneous results. The Randox Acusera Serum Indices (SI) control is designed to monitor an IVD instrument’s response in the detection of HIL interferences.
HIL interference is not novel and has been historically identified through a series of visual assessments. While haemolytic, icteric and lipemic interference causes a visual change in the sample, these methods are not quantitative and are subject to interpretation by laboratory professionals. Modern analysers have built-in capabilities for the automated detection of HIL interference which can quantitatively or semi-quantitatively measure haemolysis, icterus and lipemia, and provide and an index for each. This data can then be used to determine if a sample should be accepted for testing or rejected due to intrinsic interference.
The pre-analytical phase of laboratory testing includes collection, handling, transportation, storage, and preparation of samples. Even when the highest level of care is taken to ensure that all aspects of the pre-analytical phase are suitable and correct, errors can occur, exhibiting the need for clear and efficient quality control processes.
As part of our Acusera quality control range, Randox has developed the Serum Indices quality control to aid in the detection of the common pre-analytical error’s haemolysis, icterus and lipemia, collectively known as HIL. HIL interference can have disastrous effects on the quantification of many analytes, and it is therefore vital to determine levels of interference to improve laboratory efficiency and reduce the frequency of erroneous results.
The graph below shows the wavelengths at which each of these interferents may affect assays and the table below describes these forms of interference:
Classical determination of HIL interference took the form of a visual assessment. A sample was examined for tell-tale signs of one or more of these types of interference. However, these methods are subject to operator interpretation and lack harmonisation and uniformity across the industry. These signs are detailed in the table and illustrated in the graphic below:
Modern clinical chemistry analysers have onboard HIL detection capabilities which offer objective, semi-qualitative or qualitative analysis of these forms of interference in a more precise and consistent manner. Automation of HIL detection improves laboratory throughput along with test turnaround times and enhances the reportability of the results.
Errors at any stage of the analytical process will result in retesting of the sample. Errors in the pre-analytical phase can have repercussions such as increased cost of repeated sample collection and testing, poor test turnaround times, and more seriously, delayed or incorrect diagnosis causing an exacerbation in the condition of the patient. To add to the adverse outcomes on patients, repeated testing places additional stress on laboratory resources and staff which ultimately affects every aspect of a laboratory’s daily activities.
To correctly analyse HIL interference, absorbance readings at different strategically selected wavelengths supplement the calculation of the interference indices. C56-A recommends laboratories consider several parameters when selecting an HIL interference analysis method:
Before implementing results obtained from any method detecting HIL in patient samples, it is imperative to evaluate the specificity and sensitivity of the method at a minimum of two clinically relevant concentrations. This assessment should encompass the sensitivity of the icterus index to haemoglobin and lipids, the haemolysis index to bilirubin and lipids, and the lipemic index to haemoglobin and bilirubin.
In instances of HIL interference, laboratories bear the responsibility of managing the associated results and samples. It is crucial never to utilise an HIL index for the correction of patient results. Typically, if a sample is determined to be affected by one or more of these interferences, the laboratory should reject the result and appropriately dispose of the sample. Nonetheless, in certain scenarios, threshold values can be established. For instance, haemolysis may exert a lesser impact on samples with elevated analyte concentrations. In such cases, laboratories may opt for a distinct procedure in handling these results compared to those exhibiting haemolytic interference at lower analyte concentrations.

Medical Laboratory Professionals Week 2024
Medical Laboratory Professionals Week (MLPW) is recognised every year in the last full week of April. It’s an opportunity to increase the public understanding of, and appreciation for, the hard work of clinical laboratory staff around the world. It’s also an opportunity to inject a little fun into the laboratory. So, this year, we’ve created a Lab Professionals QC Bingo card. Have a go and see how many your laboratory can get!
How many boxes does your lab tick?
If you’re calling Bingo! you must be an Acusera 24.7 customer. If not, keep reading to find out how you can make daily life in your laboratory more straightforward.
What are Medical Laboratory Professionals?
Medicine wouldn’t be where it is today without the work of these laboratory professionals. They’re on the frontline. Around 70% of medical decisions are based on results provided by medical laboratory staff. That’s a lot of pressure on the labs to make sure their results are accurate. Clinical laboratory staff not only perform the tests used to guide diagnosis and disease prevention, but they also check all the tests they use through rigorous quality control (QC) procedures.
This involves testing samples of known values to prove that the test system and its components perform as they should and provide accurate results. To do this, laboratories require QC material. It’s important that what’s in a QC is as similar to what you’d find in a patient sample as possible. This is known as commutability. Good commutability helps limit cross-reactivity in the test and inaccurate results.
It’s also important to make sure the QC material has concentrations of analytes at similar values to those used to make diagnostic decisions. If you wanted to validate the length of the ruler on your desk, it wouldn’t be helpful to set it down on a 100m running track. Similarly, when laboratory professionals want to ensure a test is producing accurate results, they want to test the system at the critical values used to make medical decisions so that they can be confident the results at these values are accurate.
Once lab staff have confirmed the accuracy of their tests, they can begin testing patient samples. For most people, what happens to a sample after it’s taken is a bit of a mystery. MLPW is the perfect opportunity to unravel this a little:
After your sample is collected, it gets sent over to the lab. Even just moving it there needs careful handling to make sure it’s still good for testing when it arrives. Once it’s in the lab, the team checks the equipment to make sure it’s working right and giving accurate results. The QC procedure varies depending on what they’re testing for, but they always make sure their tests are legitimate. Once they’ve checked everything and carried out the tests, a pathologist looks at the results to figure out what’s going on. They use this information to help decide on the best treatment plan for you.
Even this watered-down explanation makes it sound like a lot of work, right? At Randox, we recognise the vital role and dedicated efforts of medical laboratory professionals, and the invaluable contributions they make to society, and we hope that now, you do too.

Race Against Dementia’s vision is to one day win the race against dementia by accelerating global research towards a breakthrough cure. Together we can beat dementia – faster. Currently more than 55 million people are affected by dementia worldwide. Sadly, unless something changes, 1 in 3 people born today will die with dementia.
Dementia affects different parts of the brain; some people with dementia may have trouble remembering things, while others may have trouble with language or performing tasks they used to do easily. There are many types of dementia. Each one can affect people differently, causing problems with memory, thinking and behaviour. There is unfortunately, no cure currently for this progressive disease.
As pioneers of prevention and 4-year principal partner of the Randox Grand National, Randox is proud to spread awareness of the power of preventative testing which can identify fences to clear in your health early and make you a front runner for a healthier future. As a global diagnostics company, with over 40 years of experience and a focus on preventative healthcare, Randox and Race Against Dementia are natural partners.
Throughout the three-day festival at Aintree, the charity partner will be supported to highlight the impact of the disease and to raise funds for much needed research into its prevention and cure. On Ladies Day (Friday 12th April), Randox’s sponsored race over the Grand National Fences will be titled ‘The Randox Supports Race Against Dementia Topham Chase’, with opportunities to reach out to both the racing public, and through the festival’s media coverage, to the nation.
In the pursuit of a cure for dementia, improved testing and diagnosis will both enhance patient management and greatly accelerate the race for treatment. In the last 12 months, Randox have processed over 5 million tests from health-conscious clients across the UK & Ireland, through our accessible and comprehensive in-clinic and at-home testing services.

Kate Middleton’s diagnosis reminds us that early detection is key
Kate Middleton’s recent cancer diagnosis has highlighted the importance of early detection to us all. Detecting potential health issues early means individuals can work with healthcare professionals to implement treatment plans, lifestyle changes, or preventative measures. These could mitigate, or even prevent the progression of certain diseases.
An article published by the Daily Mail, which focuses on early cancer detection MOT’s, emphasises the importance of preventative testing and treatment throughout. Charlotte Griffiths, who underwent our Everywoman Plus Tumour-Associated Markers test, stated that it is vital to keep a watchful eye for any unexpected bodily changes, such as unexplained bumps or weight loss, which may indicate a presence of cancer.
At Randox Health, we test for a range of different tumour markers, as well as genetic testing, to deliver information on cancer risk to an individual. This aims to empower people to be proactive towards improving their health and makes them aware of any potential future health risks they may have.
It is estimated that 30-50% of all cancer cases are avoidable, and in many cases, early detection is key and can save lives. Cancer that’s diagnosed at an early stage, when it isn’t too large and hasn’t spread, is more likely to be treated successfully.
Spotting cancer at an early stage can save lives, however many people do not have access to the information or services to facilitate this detection. Over 8 million people in the UK are currently awaiting diagnostic testing. At Randox Health, with over 40 years’ experience in working towards improving healthcare worldwide, we have a focus on preventative healthcare; aiming to achieve better health outcomes whilst reducing the burden on clinical services.
At Randox Health we offer genetic risk tests for inherited cancers, including Breast and Ovarian Cancer, Bowel Cancer, and others. In addition, we offer a range of full-body health tests that include common tumour-associated markers.
The results from your tests allow you to get a more accurate representation of your current health status, as well as giving you the ability to make lifestyle changes to potentially prevent future health risks.
