Open Channel Reagents

There are many different manufacturers of clinical chemistry analysers, who provide their users with extensive test menus. However, it is very difficult for these manufacturers to meet every need in a clinical lab.

Open channel reagents can help to fill any gaps in these test menus, thus providing clinical laboratories with an alternative whilst securing controls and reagents that aren’t available from their instrument provider.

Open channel reagents give laboratories the ability to bring new diagnostic tests in-house and improve patient care by reducing turnaround times, which in the long run allows for faster diagnosis and quicker treatment plan decisions.

Although open channel reagents offer a very important service to clinical laboratories, it is imperative to carefully evaluate suppliers on the quality of their assays, as well as the service and support they provide – ultimately ensuring that their reagents prove successful on another manufacturer’s clinical chemistry analyser.

Benefits of open channel

The main benefit to laboratories in introducing open channel reagents is the ability to expand their test menu without expanding their laboratory, meaning there is no need to purchase additional equipment or analysers.

Many laboratories will be outsourcing or sending tests to a reference lab. This obviously has cost implications. By bringing the test in-house laboratories can make significant savings in both cost and turnaround time.

For some markers, although instrument manufacturers might offer the test it might not always be the most superior or the best method. Open channel or third-party reagents can sometimes offer a more accurate or superior method ultimately improving the accuracy of patient testing. This will be especially important to private laboratories in which the public are paying for this service. It also helps private labs stand out from their competition.

Obstacles to open channel suppliers

Despite the many benefits of open channel reagents there can be some challenges or obstacles to implementing this type of reagent.  For example, the packaging may not be compatible with the laboratory’s specific analyser, meaning an extra step for laboratory staff and the need to pour the reagent into a component suitable for the analyser. These obstacles in most cases can be easily overcome and the benefits often outweigh the challenges.

Considerations

If a lab is considering introducing an open channel supplier, there are a few things to consider and evaluate. Firstly, laboratories should ensure whether the clinical chemistry analyser is locked or requires special packaging. In some instances, the instrument is provided with the benefit of fully open channel capabilities, however some manufacturers require to be contacted in order to implement this functionality.

How Randox can help

Rheumatoid Factor: The Most Remarkable Autoantibody in Rheumatoid Arthritis

12 October 2019

Rheumatoid Factor: The Most Remarkable Autoantibody in Rheumatoid Arthritis

The European League Against Rheumatism (EULAR) launched the ‘Don’t Delay, Connect Today’ campaign in 2017, continuing into 2019 for World Arthritis Day. The day is a global awareness day focusing on promoting the symptoms associated with rheumatic and musculoskeletal diseases (RMDs). Moreover, the world awareness day focuses on the importance of early diagnosis and access to care 1. Randox Reagents fully supports the importance of early diagnosis which aids in the early implementation of effective treatment plans, aiding in improved health outcomes. On this World Arthritis Day, Randox Reagents will delve deeper into rheumatoid factor (RF), the most remarkable autoantibody in rheumatoid arthritis.

Pathobiology of Rheumatoid Arthritis (RA)

Rheumatoid arthritis (RA), “the most common systemic inflammatory autoimmune disease” affecting 1% of the global population, is characterised by fatigue, synovial joint pain, stiffness, swelling and destruction, with severe symptoms resulting in disability. Whilst the exact cause of RA is unknown, it is believed that genetic and environmental factors play a role in triggering the disease 2, 3.  Differences in the human leukocyte antigen (HLA)-DRB1 alleles (proteins with a critical role in the immune system) have been identified as a genetic variant for RA, observed in >80% of patients, particularly in those testing positive for RF. Moreover, those with variations in the HLA-DRB1 who smoke, increase their risk of RA. As RA is more common in women (2-fold increased risk in women compared to men), hormonal influences are an area of active research, however, an inverse correlation with breastfeeding has been identified. Women who breastfeed for >13 months aids in reducing the risk of RA compared to women who have never breastfed 3, 4.

The pathophysiology of RA involves various signalling pathways and immune modulators (effector cells and cytokines) as indicated in figure 1. Joint destruction is caused by the intricate interactions of immune modulators, beginning at the synovial membrane and encompassing most IA structures, with synovitis caused by both or individually, the local activation or influx of mononuclear cells, including: B cells, T cells, dendritic cells, plasma cells, mast cells and macrophages. Consequently, “the synovial lining becomes hyperplastic, and the synovial membrane expands and forms villi”. The neutrophils, chondrocytes and synoviocytes secrete enzymes that degrades the cartilage in the joint whereas the osteoclast-rich area of the synovial membrane destroys the bone 4.

Figure 1: Schematic view of (a) a normal joint and (b) a joint affected by RA 4 

Clinical Significance of Rheumatoid Factor (RF)

Interestingly, elevated levels of RF have been observed in other autoimmune conditions such as Sjögren syndrome and systemic lupus erythematosus (SLE) as well as non-autoimmune conditions including old age and chronic infections. Despite this, RF in RA patients can be distinguished from RF in healthy individuals. RF in RA patients displays affinity maturation whereas RF in healthy individuals has low affinity and are polyreactive 2.

RF is a class of immunoglobulin (Ig) autoantibodies that are directed against the fragment crystallizable region (Fc region), the tail region of the IgG antibody. In RA, RF are produced by the B cells present in lymphoid follicles and the germinal center(GC)-like structures that mature in inflamed synovium. Most RF are IgM antibodies, but may also be IgG or IgA isoforms. IgM RF are detected in 60% to 80% of RA patients. “RF testing in RA patients has a sensitivity of 60% to 90% and a specificity of 85%” (5). RF is a highly valuable biomarker in RA 5, 2.

Key Features of the Randox Rheumatoid Factor Assay

The Randox automated latex enhanced immunoturbidimetric rheumatoid factor assay provides an accurate assessment of RF titre as the Randox rheumatoid factor calibrator is standardised against the primary WHO material, 1st British Standard 64/2. With a wide measuring range of 6.72 – 104lU/ml for the comfortable detection of clinically important results, the Randox RF assay is available in a liquid ready-to-use format for the comfortable detection of clinically important results.

Alzheimer’s Disease: The Role of Apolipoprotein E

21 September 2019

Alzheimer’s Disease: The Role of Apolipoprotein E

Since 2012, September has been devoted to raising awareness of Alzheimer’s disease (AD) with Alzheimer’s Day on 21st September each year. Dementia is the medical name attributed to a set of symptoms affecting the brain, including: difficulties with problem solving, thinking, language and memory loss. AD is the most common form of dementia accounting for 60 – 80% of cases and it is believed that half of patients with Alzheimer’s dementia (dementia due to AD) have Alzheimer’s disease 1, 2.

About Alzheimer’s Disease (AD)

AD is one of the most devastating and complex diseases characterised by:

. Neurodegeneration resulting in memory loss 2

. Neurofibrillary tangles composed of tau amyloid fibrils which associates with synapse loss 2

. Accumulation of β-amyloid (Aβ) plaques 2

. Other cognitive functions 2

It is believed that AD is expected to begin 20 years prior to symptom onset, as the small changes in the functioning of the brain are unnoticeable to the person affected. Overtime, the symptoms progress and begin to interfere with the patient’s ability to perform everyday tasks. The final stages of AD leaves the patient bed-bound, requiring 24/7 care. Ultimately, AD is fatal. Age has been identified as a risk factor for AD with 10% of people over the age of 65 affected. Moreover, AD has been recognised as a leading cause of morbidity and the sixth leading cause of mortality, but the fifth leading cause of death in over 65’s in the US 3.

Figure 1: Alzheimer’s Disease Demographic, 2019 3

Physiological Significance of Apolipoprotein E

Apolipoprotein E (Apo E) is a lipoprotein composed of 299 amino acids with a molecular weight of 34kDa.  Apo E is responsible for the regulation of homeostasis through the mediation of lipid transport from and to bodily cells and tissues. Apo E comprises of three common isoforms: apo E2, apo E3 and apo E4. The apo E isoforms differ due to differences in either the 112 and 158 amino acids, whether either arginine (ARG) or cysteine (CYS) is present 4.

Apo E3 is the parent form of apo E and is responsible for the clearance of triglyceride-rich lipoproteins. Apo E3 is associated with normal lipid plasma concentrations. Apo E2 is the rarest of the apo E isoforms and differs slightly compared to the apo E3 isoform through the substitution of a single amino acid, ARG158Cys, located near the low-density lipoprotein receptor (LDLR) recognition site. Apo E2 displays impaired binding to the receptor, prohibiting the clearance of triglyceride-rich lipoprotein remnant particles. Apo E2 is strongly associated with type-III hyperlipoproteinemia. Apo E3 also differs from apo E4, again through the substitution of a single amino acid, Cys112Arg. The main difference between apo E3 and apo E4 is that apo E4 is unaffected by the binding of the isoform to LDLR. However, apo E4 is strongly associated with dyslipidemia 5. Fig. 2 provides a visual representation of the variations in the Apo E isoforms.

Figure 2: Variations in the Apo E Isoforms 4

Apo E is expressed in numerous bodily organs with the liver presenting with the highest expression followed by the brain. Astrocytes and, to a lesser extent, microglia are the major cells responsible for the expression of apo E in the brain. In the brain, apo E, apo J and apo A-1 are predominantly expressed on distinct high-density-like lipoprotein particles. Whilst apo A-1 is the major apolipoprotein of high-density lipoproteins (HDL), in the central nervous system (CNS), apo E is the predominant apolipoprotein of HDL-like lipoproteins. HDL-like lipoproteins are the only lipoproteins present in the CNS. It is believed that the cholesterol released from apo E supports synaptogenesis 6.

Clinical Significance of Apolipoprotein E in Alzheimer’s Disease

Whilst apo E3 is the most abundant of the three isoforms, apo E4 has been known for decades to be the most significant genetic risk factor for late-onset AD. Inheriting the one copy of the apo E4 gene increases the risk of AD 2-3-fold, whilst inheriting two copies increases the risk of AD up to 12-fold 7. Whilst the underlying mechanism of apo E’s contribution to AD risk is still unclear and debatable, apo E has been identified as promoting amyloid β (Aβ) deposition and clearance as well as neurofibrillary tangles in the brain. Interestingly, Aβ-independent pathways exist for apo E in AD, which led to the unearthing of the new roles of apo E including the most recent, iron metabolism and mitochondria dysfunction 8, 9. Captivatingly, sex-related hormones may play a role in AD in apo E4 carriers as AD has been recognised to be more pronounced in women 10. Apo E4 has also been identified as impairing lipid transport, microglial responsiveness, glucose metabolism, synaptic plasticity and integrity, and cerebrovascular function and integrity. Some of these pathogeneses are independent of Aβ pathways. Furthermore, therapeutic strategies are aiming to modulate the quantity, lipidation, structural properties, Aβ interaction and receptor expression of Apo E 11.

Key Features of the Randox Apolipoprotein E Assay

Randox are one of the only manufacturers to offer the apo E assay in an automated clinical chemistry format. Utilising the immunoturbidimetric method, the Randox apo E assay is available in a liquid ready-to-use format. Not only does the Randox apo E suffer from limited interferences from bilirubin, haemoglobin, intralipid® and triglycerides for truly accurate results, it has an excellent measuring range of 1.04 – 12.3mg/dl for the comfortable detection of clinically important results. Moreover, apolipoprotein calibrator and controls are available for a complete testing package. Applications are available detailing instrument-specific settings for the convenient use of the Randox apo E assay on a wide range of clinical chemistry analysers.

Biochip Technology – Alzheimer’s Array

Utilising the Biochip Technology, Randox have developed an array to identify the risk of Alzheimer’s disease in just 3 hours with one effective test. In addition to a rapid and accurate diagnosis, this also introduces both cost and time-saving benefits. The apo E4 array is a research use only product developed for the Evidence Investigator, a semi-automated benchtop immunoassay analyser which can process up to 2376 test per hour as well as up to 44 analytes screened per biochip. The apo E4 array measures both total apo E protein levels and apo E4 protein levels directly from plasma samples as well as using a ratio, it can classify patients as negative or positive for apo E4. In turn, we can then assess their risk for the development of Alzheimer’s disease.

Overcoming the burden of Diabetes and Cardiovascular Disease

The Prevalence 

Cardiovascular disease (CVD) is the number one cause of death globally with more people dying annually from CVD than any other disease state. In 2018, according to the American Heart Association, CVD accounted for nearly 836,546 deaths in the USA (1) with over 17 million known deaths recorded worldwide. It is also proclaimed that around 1.5 million people globally die each year because of diabetes and diabetes related complications. (2) Is there a common link? Can this issue be controlled?

Studies have suggested that diabetes is one of the leading related conditions associated with increased risk of CVD death. A recent study undertaken in 2018 examined the association of many risk factors associated with CVD, the study was broken down by disease state with over 17,000 participants involved. The findings highlighted that 17.9% of these patients suffered from diabetes mellitus and death from a cardiovascular event. (3) Many other pilot and research studies discovered similar findings considering further risk factors such as high blood pressure, abnormal cholesterol and high triglycerides, obesity, lack of exercise and lifestyle choices such as smoking, alcohol and drug abuse. All of which are common with patients who suffer from diabetes, placing them at an increased risk of CVD.

Findings highlighted that over 68% of people aged over 65 living with diabetes die from some form of heart disease with 16% of individuals dying from an ischemic stroke. (4)   The ability to tackle the prevalence of increased death from CVD and diagnosis of diabetes has become a global burden with the international diabetes federation projecting that 592 million people worldwide will have diabetes by 2035. (5)

Worldwide, the increase of diabetes is becoming an economic burden on the patient and healthcare systems mainly due to the direct costs of medical care and the indirect costs of moderated productivity, tied to diabetes and CVD related morbidity and mortality. Many scholars have highlighted economic burden as a primary attribute to both macrovascular and microvascular complications such as coronary artery disease, myocardial infarction, hypertension, peripheral vascular disease, retinopathy, end-stage renal disease and neuropathy. (6)

Overcoming the Burden

As CVD is the most prevalent cause of mortality and morbidity in patients with diabetes, effective treatment and analysis is required to control and decrease the number of CVD deaths across the globe. Tackling this issue head on, the Randox RX series introduce Direct HbA1c which refers to glycated haemoglobin which is a product of haemoglobin (a protein which can be found in red blood cells) and glucose from the blood making it glycated.

Testing for HbA1c provides an indication of what an individual’s average blood sugar level has been over recent weeks/months and is generally considered as an indicator of how well the patient is managing and controlling their diabetes. This is significant for those who suffer from diabetes because the higher the levels of HbA1c, the higher the chance of an individual suffering from further diabetes related issues, therefore testing for HbA1c improves the predictions of a CVD event occurring.

The Randox RX series have Direct HbA1c testing capabilities on the RX Daytona +, RX imola and RX modena. Our latex enhanced immunoturbidimetric method which the RX series utilises makes the test simple and quick to perform. The removal of the pre-dilution step removes the risk of human error compromising your results without the need for a separate HbA1c analyser.

Offering the world’s largest test menu, the RX series has an extensive range of cardiac, diabetes and lipid tests with excellent correlation to gold standard methodologies designed to allow laboratories to expand their testing capabilities onto one single platform, providing cost savings through consolidation.

The move from Nephelometry to Immunoturbidimetric Testing

Background

In clinical diagnostics, proteins are part of a wide range of biochemical markers used to identify health and disease in patient samples. Proteins play a key role in the human body, as they are involved in almost every process and can be associated to functions and regulatory pathways that are either signature for disease onset or a target for therapeutic intervention.

There are two main methods used to detect proteins in patient samples; nephelometry and immunoturbidimetry.  Nephelometry although traditionally thought to be more sensitive can be expensive due to higher consumable costs.  In addition to this nephelometers can be inefficient and are limited by their test menu.  Immunoturbidimetric tests are an increasingly accepted alternative to nephelometry for specific protein assays, and studies have shown a close correlation between Randox immunoturbidimetric tests and nephelometry. This particularly lies with the latex enhanced immunoturbidimetry methodology utilised by Randox.

Why the RX series?

Renowned for quality and reliability, the RX series excels in clinical testing combining robust hardware, intuitive software and a world leading test menu featuring routine and novel high performing reagents.

Running specific protein tests on the RX series provides laboratories with a wide range of advantages. The move from nephelometric testing to immunoturbidimetric lowers laboratory costs as nephelometry requires the use of dedicated instruments which are much slower, have higher consumable costs and require highly trained personnel, with the disadvantage of not being able to perform any other type of assay on a single platform.

The RX series improves laboratory efficiencies not just saving costs but also time. Our range of routine clinical chemistry analysers provide users with flexibility and versatility through consolidation of testing onto one single platform.

DID YOU KNOW?

The RX Series of analysers now welcomes the addition of Direct HbA1c Testing on the RX daytona +, RX imola & RX modena

Automation vs. ELISA

Background

The technological developments and scientific innovations in the field of clinical chemistry from the early 1950’s to date have been vast, enhancing laboratory capabilities and providing the necessary support to clinicians and laboratories to improve patient diagnosis and treatment. (1) Laboratory automation today is a complex integration of robotics, computers, liquid handling and numerous other technologies with a fundamental purpose of saving time and improving performance through the elimination of human error.

Complementing this, in the early 1950’s ready-to-use assay reagent kits, with instructions for use introduced a very significant innovation to the field of automation eliminating the process of manually preparing reagent. (2)

Despite the many advancements in automation many clinical laboratories continue to use manual methods such as ELISA for some specialised tests. (3)

Inefficiencies with ELISA based methods

Manual ELISA based techniques are notoriously inefficient and are particularly draining on time and personnel due to the manual intervention required. The manual nature of the method also means there is greater potential for human error ultimately resulting in lack of sensitivity and potential for cross-reactivity. (4,5)

For many laboratories, the transition from traditional ELISA techniques to an automated method for the detection of the same analyte will significantly improve both costs and time.

Renowned for quality and reliability the RX series range of clinical chemistry analysers ensures confidence in patient testing.

DID YOU KNOW?

The RX Series of analysers allows for automation of specialised tests that previously would have only been possible via traditional ELISA methods e.g. Adiponectin, G-6PDH and Cystatin C.

 

Expanding Capabilities and Performance

With patient care holding a primary focus on clinical chemistry testing, the RX series range of semi-automated and automated analysers offer versatility to suit all laboratory requirements. Expanding your laboratory’s capabilities with our world leading extensive dedicated test menu offers cost savings through consolidation of both routine and specialised tests. By transitioning analytes historically only available as an ELISA based test, laboratories can expand their offering with ease to both patients and clinicians.

Our open system approach to clinical testing offers unique opportunities for consolidation, most of our unique and high-performance assays may be run on any clinical chemistry instrument without the need for specialised equipment.

Outperforming ELISA methodology, the RX series delivers a testing platform that requires limited or no manual preparation. With ELISA, the test is run on a 96 well plate using only a single assay with recommendations to duplicate or triplicate samples to evacuate the extent of errors, therefore increasing time and costs. The RX series of analysers each have different levels of throughput to adapt to the requirements of all laboratories.  Utilising robust hardware and intuitive software the RX series guarantees accurate and precise patient testing.

Diagnosing diabetes with the RX series

Diabetes is a lifelong condition that causes a person’s blood sugar level to become too high.

If you have diabetes, your body is unable to break down glucose into energy. This is because there’s either not enough insulin to move the glucose, or the insulin produced doesn’t work properly [1] which can lead to serious health complications.

The RX series range of analysers have one of the largest test menus available on the market which includes an extensive diabetes testing panel. Tests within the RX series diabetes panel allow for Diagnosis, Monitoring and Risk Assessment of Diabetes.

Adiponectin

An adiponectin test system is a device intended for the quantitative in vitro determination of adiponectin concentration in human serum or plasma.

Adiponectin is a protein hormone, produced and secreted by fat cells (adipocytes), which is normally found in reasonably high concentrations within the blood. Adiponectin regulates the metabolism of lipids and glucose and influences the body’s response to insulin and inflammation.

Adiponectin levels are inversely correlated with abdominal visceral fat (AVF) levels, which have proven to be a strong predictor of several pathologies including metabolic syndrome, type 2 diabetes mellitus (T2DM), cancers and cardiovascular disease (CVD). It is widely recognised that people who are overweight are at a higher risk of developing T2DM, however measure waist circumference and Body Mass Index (BMI) are not enough. As such adiponectin levels are a much more reliable indicator of at-risk patients.

A number of key publications have advocated the testing of adiponectin in clinical settings and concluded that higher adiponectin levels are associated with a lower risk of T2DM across diverse populations.[2]

Fructosamine

A fructosamine test system is a device intended for the quantitative in vitro determination of glycated protein (fructosamine) concentration in human serum or plasma.

Fructosamine is a mid-term indicator of diabetic control as it can provide information on a person’s averge blood glucose levels over the preceding 14-21 days.

 Due to the shorter time span of fructosamine, it is often used to evaluate the effectiveness of medication changes and to monitor the treatment of gestational diabetes.

HbA1c

A Haemoglobin A1c test system is a device intended for the quantitative in vitro determination of Haemoglobin A1c concentration in whole blood.

 In a diabetic patient, where blood glucose levels are abnormally elevated, the level of HbA1c also increases proportionally to the level of glucose in the blood and has been widely accepted as an indicator of the mean daily blood glucose concentration over the preceding 6-8 weeks. It is therefore, a long term indicator of diabetic control.

Read our poster on Randox’s development of a new latex enhanced immunoturbidimetric assay for the rapid direct measurement of glycated haemoglobin (HbA1c) applicable to RX series analysers by clicking here. 

 Diagnosing diabetes with the RX series

The RX series range of clinical chemistry analysers have many benefits when testing patients for diabetes. With analysers ranging from the RX misano semi-automated analyser to the RX modena which can perform up to 1200 tests per hour the RX series analysers offer a suitable platform for your laboratory, ensuring results are received in a time efficient manner. Windows based software and easily recognisable icons ensure that the RX series analysers are easy to use and allows for an enhanced laboratory productivity. Laboratory cost savings can also be achieved with a low water consumption available on each RX series analyser.

Other RX series analyser features include:

Diabetes Test Menu:

Consolidate your testing with a comprehensive diabetes testing panel available on the RX series analysers. A large number of tests can be carried out on one platform, including direct HbA1c testing, providing consolidation opportunities and real cost savings.

Accurate Testing:

High quality results are achieved first time, every time. This saves operator time and avoids unnecessary additional costs of repeat testing and reduces the possibility of patient misdiagnosis.

Unrivalled performance:

Built in inventory management system automatically calculates remaining reagent volume and the number of tests available. Superior performance means minimal downtime and swift reporting of results.

Celebrating the Randox Reagents R&D Team this Medical Laboratory Professionals Week!

Medical Laboratory Professionals Week (MLPW) is a week dedicated to increasing public understanding and appreciation for the clinical laboratory profession. During this week, we are taking the opportunity to celebrate the hard work of our Research and Development team. Allow us to provide you an insight into the life changing work of our scientists in the laboratories.

At Randox, our scientists work tirelessly to develop revolutionary diagnostic tests that are used in hospital and research laboratories across the globe.

We spoke to one of our biochemistry R&D Scientists to gain an insight into what working in a clinical chemistry laboratory entails. Emmett Donnelly, Clinical Chemistry R&D Scientist, is involved in the development of new reagents and the improvement of existing reagents. Emmett commented, “[My] role also involves the transfer and testing of existing chemistries onto new analyser platforms. Troubleshooting and resolving customer queries also forms part of a clinical analyst’s role”.  Emmett’s work is vital to ensure that patient tests are performing correctly, and to develop ground-breaking new technologies leading to better patient outcomes. To find out more about the work Emmett does, watch this video below.

Our scientists are committed to research and development and thrive knowing that their novel research is putting them at the forefront of clinical diagnostics.

In fact, prior to beginning work at Randox, Scott Paulin, Clinical Chemistry R&D team, took part in a three month expedition to Antarctica to intensely study human response-based research in athletes. A number of papers have been published in peer reviewed journals as a result of Scott’s research, as the findings have provided a useful insight into the physiological stress and responses associated with an Antarctic ultra-endurance race and nutritional counterstrategies to help maintain immune responses, function body weight and reduce stress markers. Read the full article here.

At Randox, our scientists are of the highest calibre, with vast experience and expertise which ensures we are producing the highest quality range of clinical diagnostic tests.

Excitingly as a result, American astronauts have enlisted our help to test their antioxidant levels before they go to space! This is essential as it ensures astronauts can survive long periods of time away from earth. To find out more about how important our Total Antioxidant Status (TAS) test is for astronauts, read our blog post here.

The invaluable work our scientists undertake in the laboratory is vital to ensure healthcare is advanced globally. Thanks to those in our Research and Development team, we are proud to be able to offer the widest range of clinical chemistry reagents and unique tests for medical diagnosis. Due to our scientist’s dedication to research, a continual focus is placed on developing tests that assess the risk of diseases, rather than diagnosing the illness after it has occurred. As a result, Randox are helping to change healthcare, as patients are provided the ability to take preventative action early. In the words of our R&D scientist Emmett Donnelly, “for me, my work supports the old saying prevention is better than cure”.

We hope you have enjoyed reading about our fantastic team of R&D Scientists! If you would like to find out more about the work of Randox Reagents, please get in contact by emailing: reagents@randox.com or click here to view our homepage.
