The updated collaboration opens up PayPoint’s extensive retail network to offer increased convenience to travellers returning to the UK

Randox and PayPoint have today announced an expansion of their partnership, to boost access to COVID-19 testing and provide a vital service to travellers returning to the UK, in line with the Government’s new arrival requirements for Day 2 testing, announced on Wednesday 5th January.

The expanded partnership between PayPoint and Randox will mean even easier access to low-cost COVID-19 testing, by enabling people to order a Randox test online for click and collect at a local store within the Collect+ network, initially available in over 5,000 locations, and soon in over 10,000 locations nationwide.

The service launches on 7th January 2022 to coincide with changes to travel policy which, from 4am on 9th January, allows fully vaccinated arrivals from non-red list countries to take a lateral flow (antigen) test, with a PCR test only required if a positive lateral flow result is returned.

In addition, from mid-January, PayPoint will give consumers the ability to walk into a local store and pick up a test immediately in over 2,500 locations, with no need to order online. This service will be offered in partnership with major convenience retailers including Scotmid Co-operative and Spar in the North West and Scotland.

Dr Peter FitzGerald, Managing Director at Randox said: “By drawing on our 40 years’ diagnostics experience, unparalleled testing capacity, and well-established logistics network, which now includes an extensive number of new locations from PayPoint, Randox is able to respond quickly to changing travel requirements and simplify the process of ordering Day 2 lateral flow tests.

“The availability of value for money tests that can be collected at the customer’s convenience thanks to our partnership with PayPoint means people in the UK don’t need to wait for home delivery or a walk-in clinic appointment when ordering a COVID-19 test.”

Nick Wiles, Chief Executive at PayPoint said: “Our expanded partnership with Randox will deliver yet another vital service to help keep people safe in communities across the UK.  Consumer convenience and accessibility are at the very heart of what we do and this is another example of our agility, responsiveness and the great relationships we have with our retailer partners in the ever-changing landscape across the UK.”

Day 2 lateral flow tests must be ordered before travel to England and can be ordered from 4am on 7th January. Thanks to the updated collaboration between PayPoint and Randox, people can now conveniently collect these tests from local stores for just £18.95, rather than waiting at home for deliveries to arrive.

Using the free Randox CertiFly App results are processed within 3 hours and a report delivered in-app and via email, allowing arrivals into England to complete their Day 2 test conveniently in the comfort of their own home, and for individuals who test positive, potentially reducing the amount of time they need to isolate.

COVID-19 Testing        News        Contact Us

25th November 2021: Randox Health launches COVID-19 Travel Centre in Enniskillen

A COVID-19 Testing Service launches this week in a new Randox Health Travel Centre in Enniskillen, offering COVID tests from just £30.

The testing service from Randox, a laboratory partner in the UK’s National COVID-19 Testing Programme, offers rapid lateral flow (LFD) tests – with results in just 60 minutes – for those who are eligible to take an LFD for their Day 2 testing requirements.

The service in Enniskillen will also provide gold-standard PCR testing for those who need it for pre-departure screening, on-arrival testing on Day 2 and Day 8, or simply for peace of mind, with Express PCR tests returning results in as little as 3 hours.

Sophie Boyd, Project Manager for the Randox COVID-19 Testing Service, explained;       

 “In addition to our Travel Centres at Belfast International Airport, Belfast City Airport, Holywood and Crumlin, we are pleased to expand our testing service to Enniskillen, to serve the Fermanagh area with our accurate and cost-effective COVID-19 tests.

“Whilst travel guidance during the pandemic continues to evolve, testing will remain a key part of the response to COVID-19 – not only to identify outbreaks, isolate cases and prevent further spread, but also to assist with a return to social and economic normality.”

From 4am on 31st October 2021, changes to travel guidance for those arriving in Northern Ireland from countries not on the red list came into effect.

For vaccinated passengers, lateral flow (antigen) tests may now be used for post-arrival testing as an alternative to PCR testing, with a photograph of the completed lateral flow test required in order to verify the result.

Sophie continued;

“In support of changes to government travel guidance, our COVID-19 testing service has evolved to now include lateral flow testing in addition to our gold-standard PCR testing, and Randox is recognised as a provider of both services on the official government list.

“Randox is committed to providing competitive, effective and efficient testing to support holidaymakers and those undertaking international travel and the opening of the Randox Health Travel Centre in Enniskillen is another positive step towards the normalization of travel and other social activities.”

The Randox Health Travel Centre in Enniskillen is open to all asymptomatic individuals and is conveniently located on the Tempo Road.

Why are Neutralising Antibody tests important now?

COVID-19 Testing        News        Contact Us

27 October 2021- Why are Neutralising Antibody tests important now? 

Being prone to more frequent infections may mean that you have a weak immune system. With everything going on in the world, including COVID-19, this is important information that you need to know about yourself. As it stands, the pace of the vaccine booster rollout has slowed down and priority is given to people who are most vulnerable from developing a COVID-19 infection. This will offer those individuals the fullest protection against the virus this winter.  According to John Roberts, from the COVID-19 Actuaries Response Group, “At the start of the booster campaign, the health secretary Sajid Javid said: ‘We will protect the most vulnerable through the winter months’. But at the current rate it is going to be well through winter before we get through those first groups.”  This was stated on a BBC news article. (1)

This leads into the question that everybody is wondering…. Do we really need the booster vaccine? Infectious diseases expert, Professor Angus Dalgleish has commented during an interview on Good morning Britain that we should try another strategy.  A strategy where we should test people’s immunity first to see if they need the booster vaccine. He stated, “It should not be difficult for one test to see what your immune response to your last vaccine is or if you have had very bad COVID, have you got a good immune response and do you need the booster”. (2)

Laith Jamal Abu-Raddad, an infectious-disease epidemiologist at Weill Cornell Medicine—Qatar in Doha has also stated in an article from Nature that “Wasting resources on boosters for those who are already protected against severe disease does not really make too much sense,” (3)

The Randox SARS-CoV-2 Neutralising Antibody tests detects antibody levels post-vaccination to determine eligibility for a booster vaccination. These tests utilise patented biochip technology to detect neutralising antibodies to the Wuhan and Delta SARS-CoV-2 variants. There is a need for tests of this kind to provide an accurate estimate of immunity, monitor vaccine effectiveness and the frequency of post-vaccine breakthrough infections with variants of concern. Recent studies indicate that the delta variant is capable of re-infection even in fully vaccinated individuals and that a significant proportion of fully vaccinated individuals with breakthrough infections can transmit the virus to others.

The SARS-CoV-2 Neutralising Antibody tests are a quick and effective way to determine:

  • Longevity of immune response with response to post-vaccine infection, and variants of concern.
  • Population surveillance and testing of those at risk of sub-optimal vaccine response.
  • Measure antibody levels post-vaccination to determine eligibility for a booster vaccination.
  • Accurately detects antibodies that are capable of inhibiting virus replication and neutralizing the infectivity of the virus.

Randox and Collect+ join forces to boost accessibility of reduced-cost PCR and Lateral Flow tests

COVID-19 Testing        News        Contact Us

25th October 2021: Randox and Collect+ join forces to boost accessibility of reduced-cost PCR and Lateral Flow tests

Today, Randox and Collect+ announce a new partnership that will provide even easier, nationwide access to low-cost COVID-19 testing. The partnership enables consumers to order a new reduced-cost PCR (£34.99) or lateral flow (£19.99) test online and then pick it up on the same day from participating shopping centres within the Collect+ network. This first of its kind partnership means people in the UK no longer need to wait for a home delivery or walk-in clinic access when ordering a COVID-19 test.

With an initial 29 locations already open, this collaboration plans to expand to more than 100 Collect+ locations in the coming weeks, and hopes to go further to utilise even more of the Collect+ network over the medium to longer term. Randox’s collaboration with Collect+ has not only simplified the logistics process but has sought to help support their retailer partners and provide another vital service at the heart of local communities.

In recognition of changes to travel guidelines for England, which state that from 24th October, fully vaccinated passengers from non-red list countries can take a lateral flow test for their day-two post-arrival checks, Randox now offers home testing kits as both PCR and lateral flow, to aid pre-departure testing and any current and future day 2 requirements. PCR and lateral flow tests are available at the newly reduced prices of £34.99 and £19.99  respectively when using Collect+ click and collect.

Philip Robinson, VP Sales at Randox said: “As guidelines change and the country continues to open up, Randox is able to support any travel testing requirements by utilising our extensive diagnostics experience and logistics network, and offering value for money for both PCR and lateral flow tests that can be collected at the customer’s convenience thanks to our new partnership with the Collect + service from PayPoint.

 “Our significant investment in capacity expansion and in logistics solutions such as Collect + click and collect sites that further simplify the process of ordering COVID-19 tests, have allowed us to make ongoing price reductions, demonstrating our commitment to helping people live their lives as easily and normally as possible.”

Nick Williams, Head of Strategic Partners & Product, Collect+ said:This is an exciting and important partnership for Collect+, which has always had consumer convenience and accessibility at the very heart of its operations. Randox has been instrumental in making COVID-19 tests easily available to people around the UK and this collaboration will see that country wide impact become even more meaningful.”

As Randox remains amongst the very largest COVID-19 laboratories in the UK and Europe and to date has processed almost 20 million tests, facilitated by drive-thru services, in-person clinics and home delivery options, the introduction of Collect+ locations further diversifies the efforts made by the company to make testing more accessible.

The number of Randox shopping centres with Randox Collect + locations now totals 29, including but not limited to Liverpool ONE, Waterloo Station, Brent Cross London, and Festival Place Basingstoke.

Neil Churchill, Centre Director, Festival Place Shopping Centre, commented:

“The Randox click and collect service is a good illustration of Festival Place’s growing position as an all-day destination, offering a variety of services to complement the traditional retail offer. Our Guest Services team have noted an increase in visitors, from all across Europe, passing through Festival Place to collect the Randox kits required for their travel. Customers appreciate the option to pick up their kits close to home while able to do their shopping at the same time.”

Randox listed on Gov.uk as provider of Day 2 Lateral Flow COVID tests

COVID-19 Testing        News        Contact Us

22nd October 2021: Randox listed on Gov.uk as provider of Day 2 Lateral Flow COVID tests

Following changes to government travel guidance, lateral flow (antigen) tests will be the Day 2 requirement for any fully vaccinated passengers arriving into England, from 24th October.  This change applies only to fully vaccinated international travellers and most under 18s arriving into England from non-red list countries, and will replace the previous PCR testing requirement.

This change will come into effect for anyone returning into England, following the half-term break and tests can be completed on or before day two of their arrival.

Randox is listed on Gov.uk as a provider of Day 2 Lateral Flow COVID tests.

Randox offers multiple lateral flow testing solutions, including the new Randox CertiFly rapid antigen test, which will allow you to complete your Day 2 test in the comfort of your own home from only £19.99.

The Randox CertiFly Lateral Flow test is designed to simplify foreign travel for passengers and facilitate the efficient transfer of secure and verified information through an easy to use mobile app.

Available for free through the App Store and coming soon on Google Play, the app securely identifies customers and processes testing results within 3 hours.

To order a Lateral Flow Home Testing Kit visit https://covid.randox.com/day-2-test-at-home/

If your preference is to take your Day 2 test on arrival at the airport then you have the option of visiting one of our many travel centres conveniently located across the UK.

From £35 you can organise for a Sample Collection Officer to take your swab at clinics including Manchester Airport, Heathrow Airport, Stansted Airport, East Midlands Airport, Liverpool ONE, and Waterloo Station London.

To book an in-clinic Day 2 Lateral Flow appointment visit https://covid.randox.com/day-2-test-in-clinic/

Background to Government changes

Eligible fully vaccinated arrivals and those with an approved vaccine from non-red countries will be able to replace the test taken as soon as possible on arrival, referred to as the Day 2 PCR test, with a self-administered lateral flow device (“LFD”). Arrivals must have had a complete course of a recognised vaccine at least 14 days before arriving in England. They will not be required to take a Pre-Departure Test or a Day 8 test.

Day 2 Lateral Flow

Passengers who do not meet the “eligible traveller” criteria will still have to take a pre-departure test, a Day 2 and Day 8 PCR test and self-isolate for 10 days upon their return from a non-red list country. Test to Release will remain an option for unvaccinated passengers who wish to shorten their isolation period.

How will the new lateral flow system work?

Passengers will be required to take a photograph of their completed lateral flow test alongside their booking reference number which Randox will provide via email on receipt of order. Randox will then verify the result of your sample. Passengers will still be required to complete a passenger locator form to return to England.

Anyone who tests positive will be required to self-isolate and take a confirmatory PCR test. The government have confirmed that anyone who has previously purchased a Randox PCR test will not need to buy another lateral flow (antigen) test.

With proven testing capability and well-established logistics and customer support services, Randox is strongly placed to allow all travellers to the UK to complete their antigen test with ease  – offering same day results up to 11.59pm.

Randox launch authentication app for Day 2 Lateral Flow tests for vaccinated international arrival

COVID-19 Testing        News        Contact Us

18th October 2021: Randox launch authentication app for Day 2 Lateral Flow tests for vaccinated international arrivals

Randox, the UK’s largest diagnostics company, today announces that it is launching the Randox CertiFly App, a mobile application designed to securely process and certify results for both pre departure and Day 2 lateral flow tests – the latter a requirement for vaccinated international arrivals in the UK from 24th October.

The app, which applies ID verification technology, is designed to simplify foreign travel and facilitate the efficient transfer of secure and verified information through three simple steps:

Step 1 – Download the Randox CertiFly App and scan your passport to register

Step 2 – Collect your sample using a Randox CertiFly lateral flow testing kit

Step 3 – Scan your result using the app and receive certificate in app and by email

The app, which is solely for use with Randox Certifly lateral flow tests, is free to download.  The lateral flow tests, which are ordered from Randox and cost as little as £20,  are then used in combination with the app to capture the individual’s ID and securely upload the test result.  The identity of users will be validated by scanning passports into the system, with future versions of the app featuring facial recognition software to further increase security.

Available in just 15 minutes, test results are processed using Randox CertiFly’s AI software, before being confirmed manually by a healthcare professional. As applicable, a Day 2 or fit-to-fly certificate will then be issued to the user and stored in the app for easy access.

Each Randox CertiFly lateral flow testing kit has a unique single-use QR code that can be registered with the app. Testing kits, which can be purchased from the Randox Health website, include swab, extraction buffer tube, waste bag, tube holder, package insert and test cassette. The app is available now for iOS and Android devices.

Commenting on the announcement, Dr Peter FitzGerald CBE, Managing Director at Randox, said:

“COVID-19 has severely impacted the way that we travel but, thankfully, testing technology has been able to help the world open up again. At Randox, we are proud to have been at the heart of UK testing and we are continuously looking at ways to make improvements for our customers. Randox has been helping millions of passengers travel safely since the onset of the pandemic by providing innovative testing solutions, like the Randox CertiFly app, that fulfil testing requirements for those who need to travel, whilst keeping costs as low as possible.”

randox certifly £20

The Importance of Diagnostic Testing in SARS-CoV-2 Adverse Outcomes

SARS-CoV-2 (COVID-19), a highly contagious disease, primarily manifests as an acute respiratory illness, however, for those with health complications, including: autoimmune diseases, asthma, heart disease and diabetes, the risk of developing serious illness and adverse outcomes is much greater. It is estimated that 1 in 6 will experience adverse outcomes that could be life-threatening 1. The spread and devastation of COVID-19 highlights the vital role laboratory diagnostics plays in the diagnosis and management of suspected and affected patients. As the COVID pandemic continues, it is imperative that fast and accurate diagnostic testing strategies are implemented for effective risk stratification and monitoring of treatment and recovery.

In this article, we will review how Randox Reagents can aid in diagnosing and managing SARS-CoV-2 adverse outcomes.


Cytokine Storms

The immune system activates a pro-inflammatory response to enhance host immunity against viruses and decrease colonisation and infection, but only if the pro-inflammatory response is controlled. Uncontrolled pro-inflammatory responses can result in a cytokine storm 2. A cytokine storm is a serious complication associated with SARS-CoV-2, which can trigger life-threatening pneumonia, acute respiratory distress syndrome (ARDS) and multiple organ failure 3, 4. Cytokine storms occur in 5% of severe COVID-19 cases, with several inflammatory cytokines observed at high levels. Due to the elevation of several pro-inflammatory and anti-inflammatory cytokines, a multiplex immunoassay approach can offer several advantages over the widely utilised single ELISA tests. The simultaneous detection of multiple cytokines from a single patient sample will provide clinicians with a comprehensive overview of cytokine markers and complete patient profile, facilitating a personalised treatment plan to be implemented 5, 6.

Cytokine Storms Image


In COVID-19 patients, CRP testing has proved to perform well in discriminating disease severity and predicting adverse outcomes 7. Elevated CRP levels have been identified in 86% of patients admitted to hospital. CRP measurements are useful in diagnosis, prognosis and monitoring for clinical improvements or deterioration. Moreover, the acute phase reactant, ferritin, has been observed to increase in approximately 60% of COVID-19 patients. In the critically ill COVID-19 patients, extremely elevated ferritin concentrations were recorded, which could be attributed to a cytokine storm and secondary haemophagocytic lymphohistiocytosis (a hyper-inflammatory syndrome associated with multi-organ failure) 8.

Renal Function

Acute kidney injury (AKI) is a common complication in diabetic patients who test positive for COVID-19. Regardless, the National Institute for Health and Care Excellence (NICE) recommend AKI testing in all COVID-19 patients upon hospital admission and their condition monitored throughout their stay 9.

The most commonly utilised screening test for renal impairment is serum creatinine (SCr); however, it is important to consider the accuracy and reliability of the method. Two commercially available methods exist for SCr determination: Jaffe and enzymatic. Whilst the Jaffe method is less expensive, it is more susceptible to interferences which can lead to the misdiagnosis of patients, which isn’t ideal in the current pandemic 7. Moreover, the sensitivity of SCr, regardless of method, in the early detection of renal disease is poor, as SCr is insensitive to small changes in glomerular filtration rate (GFR). Up to 50% of renal function can potentially be lost before significant SCr levels become detectable 8, 9. In comparison, cystatin C (CysC) is a superior marker of renal function and is useful in the determination of the extent of renal damage, as well as distinguishing those with severe and mild COVID-19 10.

Hepatic Function

Liver Image

Abnormal liver function tests significantly increases a COVID-19 patients risk of developing severe disease and complications such as pneumonia 11. Bilirubin levels, 3 times the upper limit have been observed in COVID-19 patients 11, 12. Whilst the diazo method is commonly utilised in bilirubin testing, superior methods exist. The vanadate oxidation (VO) method offers several advantages particularly in haemolytic and lipemic samples. These advantages are particularly evident in neonatal and infant populations where haemolysis is extremely common. Moreover, the VO method offers a wider analytical measurement range for the comfortable detection of clinically important results 13.

Other liver function markers are known to be elevated in COVID-19 patients including both AST and ALT, with markers like albumin decreased.

The Importance of Lp(a) Testing

Lipoprotein(a) / Lp(a), a strong independent marker of cardiovascular disease risk has recently been identified as a key risk marker of cardiovascular complications in COVID-19 patients. Those with either baseline elevated or elevated levels of Lp(a) following COVID-19 infection may be at a significantly increased risk of developing thromboses. Consideration should be given to measurement of Lp(a) and prophylactic anticoagulation of infected patients to reduce the risk. Elevated Lp(a) levels may also cause acute destabilization of pre-existing but quiescent, atherosclerotic plaques, which could induce an acute myocardial infarction (AMI) or cerebrovascular accident (CVA) (stroke) 14.

The size heterogeneity of apo(a) isoforms represents the biggest challenge faced by laboratories in accurately measuring Lp(a).  The variable numbers of repeated KIV-2 units in act as multiple epitopes, and so standardisation across calibrators is vital. Unless the calibrants have the same range of isoforms as test samples, those with higher numbers of the KIV-2 repeat, will represent with an overestimation in Lp(a) concentrations and those with smaller numbers of the KIV-2 repeat, will represent with an underestimation. The smaller isoforms are strongly associated with higher Lp(a) concentrations 15.

Lp(a) assays that are standardised to the WHO/IFCC (World Health Organization/International Federation of Clinical Chemistry) reference material, transferring values from mg/dl to nmol/l are more uniform. The assay considered the most reliable commercially available Lp(a) assay is so because: 15

1. The isoform size variations are reduced as a range of calibrators from separate pools of serum used, which covered a range of Lp(a) concentrations.

2. The isoform size and concentrations are inversely correlated, better matching calibrants with test samples.

3. Methods are calibrated in nmol/l and traceable to WHO/IFCC reference material and give acceptable bias compared with the Northwest Lipid Metabolism and Diabetes Research Laboratory (NLMDRKL) gold standard method.

Diagnostics Uses

  • Physiological Significance

  • COVID-19

The G6PD gene provides the instructions for marking the glucose-6-phosphate dehydrogenase (G6PDH) enzyme 1. G6PDH is a cytosolic enzyme located on the long arm of the X-chromosome of bodily cells and so is an inherited x-linked disorder. G6PDH is involved in the normal processing of carbohydrate and the prevention of cellular damage from reactive oxygen species (ROS). In doing so, G6PDH provides substrates to prevent oxidative damage. G6PDH plays a critical role in red blood cells, protecting them from damage and premature destruction. The two main products of G6PDH are:  ribose-5-phosphatase which is important for DNA, the chemical cousin of RNA; and NADPH which protects the body from ROS 1, 2.

Glucose-6-phosphate dehydrogenase (G6PDH/G6PD) deficiency is the most common enzyme deficiency in the pentose phosphate pathway, affecting more than 400 million people globally.  G6PDH deficiency is an X-linked recessive disorder mainly affecting RBC’s 2.

A defect in the G6PDH enzyme results in premature haemolysis (break down of RBC’s).  If the bone marrow cannot compensate for the reduction of RBC’s, haemolytic anaemia can occur.  Many individuals that are glucose-6-phosphate dehydrogenase deficient are asymptomatic most of the time, however when they are exposed to certain triggering factors, they can develop acute haemolytic anaemia (AHA), which can be life-threatening, especially in children.  Symptoms associated with G6PDH deficiency can include paleness, jaundice, dark urine, fatigue, shortness of breath, a sudden rise in body temperature, lower back pain, splenomegaly (enlarged spleen) and a rapid heart rate.  Other symptoms can include nausea, diarrhoea or abdominal discomfort.  It has been noted that glucose-6-phosphate dehydrogenase deficiency is a significant cause of mild to severe jaundice in new-borns. Early and accurate diagnosis of G6PDH deficiency is essential in ensuring the successful management of haemolytic anaemia 1, 2.

Of all malaria cases reported in Latin America and the Caribbean, 42% are attributed to Brazil. However, in recent years, progress has been made towards the elimination of the malaria burden, reaching the lowest levels in the past 35 years (143, 910 cases and 41 confirmed malaria-related deaths). Whilst the transmission area of malaria has significantly reduced, 99.5% of Brazil’s malaria burden is attributed to the Amazon Basin 3. The predominant contributor to the malaria outbreak in Brazil is attributed to the plasmodium vivax parasites which can cause severe and fatal complications in glucose-6-phosphate dehydrogenase (G6PDH) deficient individuals. Individuals infected with malaria are treated with primaquine, however, in G6PDH deficient individuals, this treatment can induce haemolytic anaemia, and so, G6PDH screening is vital 4.

A Brazilian study, published in the Malaria Journal prospectively evaluated 516 male volunteers within the Alto do Juruá, an area characterized by a high prevalence of plasmodium vivax, to determine the prevalence of G6PDH. The study found that 4.5% of the study group were G6PDH deficient and were at a high risk of haemolytic anaemia if treated with primaquine. As such, the routine screening of G6PDH deficiency in Brazil to personalize the treatment of patients with vivax malaria, is crucial for malaria elimination 4.

Chloroquine, an anti-malaria drug, has been selected to aid in treating those with COVID-19 following preliminary research and a limited study in Australia which highlighted that chloroquine showed promise in eradicating the virus. Moreover, Chinese research highlighted the efficacy and safety of chloroquine in treating pneumonia in COVID-19 patients 5.

It is believed that COVID-19 is expected to spread to areas where G6PDH deficiency is more common, however, serious consideration must be given to treatment decisions using chloroquine as chloroquine-induced haemolysis is the result to decreased G6PDH activity 6.
