Randox Reagents Team Celebrate British Science Week!
Randox Reagents Team Celebrate British Science Week!
This British Science Week 2016, the Reagents Team at Randox are celebrating the hard work our Research and Development Team put in every day, to help bring the best quality diagnostic reagents to the market.
We caught up with Emmet Donnelly, Clinical Chemistry R&D Scientist, to explain a bit about what his work involves, and how it’s impacting on global healthcare!
What is your position and what does it involve?
I am a Clinical Analyst on the Clinical Chemistry R&D Team. This role involves the development of new reagents and the improvement of existing reagents. It 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.
For those of us who aren’t in the industry, can you explain what reagents and assays are?
A reagent is a chemical used to detect the quantity of another component or analyte in a sample (blood or urine), for example a cholesterol reagent contains the necessary chemical make-up to detect the amount of cholesterol in a patient sample.
An assay is the procedure involved in determining the amount of analyte in a sample using a reagent. For example a cholesterol assay involves enzymes within the reagent breaking the cholesterol down into its chemical constituents. These constituents react with other components in the reagent to form a coloured indicator. If this assay is being used on a clinical chemistry analyser, light is passed through the coloured mixture and the amount of light absorbed is proportional to the concentration of analyte in the sample.
How does you work impact on global healthcare?
The diagnostic assays are a vital component in the diagnosis of disease. In order to find out, for example, why a patient is feeling poorly they must first have a blood test to measure all their blood analytes. This will help diagnose the underlying problem and aid in choosing and monitoring the correct treatment for that patient. For example a patient suffering from diabetes must constantly have their glucose levels monitored so that correct doses of insulin can be administered.
What is your favourite Randox product and why?
I like some of the old products like glucose, ALP and cholesterol because they are the tried and tested reagents that are essential for monitoring the health of our vital organs. These always comprise part of the panel of testing to be done when our GP takes a blood sample from us.
I also like the newer reagent products such as the DOA (Drugs of Abuse) reagents. They offer a means of detecting illegal substances in urine samples offering aid to law enforcement.

Randox diagnostic tests are out of this world!
The scientists here at Randox work hard on research and development, to ensure that we are producing the highest quality range of clinical diagnostic tests on the market. Excitingly, as a result American astronauts have recently enlisted our help to test their antioxidant levels before they go to space!
Why do astronauts need their antioxidant levels tested?
It is very important for astronauts to monitor their health and take plenty of antioxidant supplements in order to prevent bodily damage and to survive long periods of time in space! The main concern is to monitor and control the levels of free radicals in the body as well as to prevent damage from radiation which can cause bone and muscle loss and diminished immunity.
What can antioxidants prevent the astronauts against?
Bone loss – Bone loss can happen during long periods of microgravity (weightlessness), where astronauts can suffer from calcium, vitamin D and vitamin K deficiency. Vitamin supplementation paired with exercise can protect against this.
Vision-related hazards – Astronauts can suffer from degraded vision, caused by a shortage of vitamin B, especially vitamin B9 (folic acid).
Magnesium deficiencies – There can be a lack of magnesium due to a loss of fluid volume in the blood circulation which can cause damage to DNA stabilisation. This lowers the ability of mitochondria to produce cellular energy (mitochondria is part of the cell related to respiration and energy production).
Memory loss – Lipoic acid can reduce the risk of astronauts developing memory problems which can occur through being exposed to radiation.
Radiation – A reduction in the capacity of astronaut antioxidant defence systems and damage to DNA can occur due to exposure to space radiation. Vitamins A, C, E, zinc, selenium, glutathione and sulphur compounds are all nutrients which should be supplemented to their diet to counter these effects.
The Total Antioxidant Status (TAS) test from Randox can help give astronauts an overall picture of their antioxidant health, which helps them manage their wellbeing in space.

A day in the life of a Molecular Biologist
Molecular Biologist, Michael Mullan, was fascinated by science from a young age. For him, it was only natural to progress into a career as a scientist. Being able to use his skills of problem-solving to improve diagnostic technologies leads him to describe a career in science as fascinating, challenging and rewarding. Read what he has to say…
Can you describe a typical working day?
There’s no such thing! Each day varies so much and is usually split up between carrying out laboratory work, and analysing and interpreting data. I work in the Molecular Diagnostics department in Randox Laboratories with a team of Molecular Biologists and Engineers, and we develop DNA-based diagnostic tests that can detect pathogens, genetic mutations and even calculate a patient’s risk of developing certain illnesses.
What has been your educational / career path to this post?
From a young age I was fascinated by science, so I chose to study Triple Award Science at GCSE level and Biology, Chemistry and ICT at A level. Having enjoyed science at school I decided to study Molecular Biology at Queen’s University Belfast and then moved on to a Master’s degree in Molecular Biology and Biotechnology, because I wanted to use my aptitude for problem-solving to improve the diagnostic technologies which are so important in healthcare. I started on the Graduate Development Program here at Randox where I worked as a Technical Support Specialist before moving into my current position in the Molecular Diagnostics department.
What transferable skills have you used in your various roles that have come from your STEM training?
My time at university prepared me well for my current job as I often research papers and write reports, and have to follow good lab practice. Transferable skills such as these are the building blocks of any career, however those developed through scientific education are highly sought after by all employers, even those outside the science sector. Good communication skills are essential, and my time in Technical Support helped me to develop my ability to communicate with customers and colleagues. Organisational skills are also important to carry out experiments correctly and safely, and to record methods and results in an understandable and clear way.
How does your work as a Molecular Biologist make the world a better place?
Our Molecular Diagnostic tests provide highly specific test results for patients based on their genetic makeup and this opens the door for personalised medicine. The work my team and I do improves the accuracy and speed of patient diagnosis; faster, more informative diagnosis can save lives.
What do you really like about your job?
My favourite thing about my job is that no two days are ever the same. Working as part of a multidisciplinary team who work on a range of different projects takes me completely out of my comfort zone and challenges me to think outside the box.
Can you say anything about the future job prospects in your industry?
The Biotechnology industry is currently expanding at a phenomenal pace. So much so that students in school today who decide to go down a scientific career path will be using technologies that haven’t even been invented yet. That is such an exciting prospect.
How do you balance your career with your personal life?
My working day allows me to have plenty of free time to myself in the evenings and also at weekends. Working in a laboratory environment can be challenging and extremely fast-paced at times so I like to go to the gym and run to let off steam.
Would you recommend Molecular Biology to young people planning their career?
Yes, 100%. If you are a young person with a thirst for knowledge, particularly in science, and want to spend your days doing something you love that really makes a difference, then a career in Molecular Biology is perfect for you.

Support World Kidney Day with Randox Renal Function Tests
World Kidney Day is a global campaign aimed at raising awareness of the importance of our kidneys to our overall health. It aims to reduce the frequency and impact of kidney disease and its associated health problems worldwide.
The main objectives of World Kidney Day are to educate all medical professionals about their key role in detecting and reducing the risk of Chronic Kidney Disease (CKD), particularly in high risk populations, and to stress the important role of local and national health authorities in controlling the CKD epidemic. On World Kidney Day all governments are encouraged to take action and invest in further kidney screening.
World Kidney Day highlights the need for more accurate kidney function testing for better diagnosis and monitoring of kidney function to assist in the development of appropriate treatment plans. As such, Randox have invested in the development of more sensitive and specific renal function tests such as cystatin C, which may be requested if kidney function is found to be borderline using the more routinely run creatinine test. Doctors may request cystatin C to check for early kidney disease and/or to monitor known impairment over time.
Cystatin C is a particularly useful marker of renal function in patients where creatinine measurements are not suitable e.g. individuals who are obese, malnourished, have liver cirrhosis or reduced muscle mass. Importantly, unlike creatinine, cystatin C does not have a ‘blind area’ – up to 50% of renal function can be lost before significant creatinine elevation occurs. Cystatin C is extremely sensitive to very small changes in GFR and is therefore capable of detecting early stage kidney dysfunction.
Both World Kidney Day and Randox are working towards improving healthcare worldwide. With a comprehensive panel of high performance reagents, Randox are helping with the detection and characterisation of renal function problems. With early diagnosis it will be possible to keep kidney problems from getting worse, therefore lowering the number of those diagnosed with CKD worldwide.
If you are a clinician or lab interested in running renal function assays, Randox offers a large range of high quality routine and niche assays including: Cystatin C, Creatinine Enzymatic and Jaffe, Microalbumin, Urinary Protein, Urea, Sodium, Potassium, Albumin, Ammonia, β2- Microglobulin, Calcium, Chloride, Glucose, HbA1c, IgG, LDH, Magnesium, Phosphorus (Inorganic), and Uric Acid. These can be run on most automated biochemistry analysers.

Immunoturbidimetry vs nephelometry for protein detection
Immunoturbidimetry methods have become the main technique for performing protein tests. The transition from nephelometry has been cautious but is increasing as laboratories enjoy the comparability and flexibility of immunoturbidimetry.
Immunoturbidimetry and nephelometry both measure the turbidity of a sample to determine the level of an analyte. Upon addition of the assay reagent, antibodies and antigen cluster to form an immune complex that precipitates, increasing the turbidity of the sample. When light is passed through the reaction solution, some light is scattered by the sample, some light is absorbed by the sample and the rest passes through the sample.
Immunoturbidimetry measures the absorbance of the light by the sample, nephelometry measures the light scattered at a fixed angle. The level of analyte is determined by comparison with a calibrator of known concentration.
Immunoturbidimetry is ideal for the detection of proteins, where the analyte concentration is inversely proportional to the transmitted light signal. Historically nephelometry has been more sensitive than conventional immunoturbidimetry. In latex-enhanced immunoturbidimetry, inert microscopic particles enlarge the immune complexes, amplifying the reaction and significantly increasing the sensitivity of the reaction.
Nephelometers are dedicated analysers only capable of performing this type of assay. In addition, they are:
- slow
- have high consumable costs
- require highly trained personnel
Immunoturbidimetric tests are carried out on routine biochemistry analysers that are:
- versatile
- fast
- cost-effective
- offer longer reagent stability
- sensitive
The main advantage of nephelometry was its sensitivity; however latex-enhanced immunoturbidimetry has closed this gap. 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.
If you are interested in running your protein assays on a routine biochemistry analyser, Randox offers a large range of high quality routine and niche protein assays that can be run on most automated analysers, including: Alpha-I acid glycoprotein; alpha-I antitrypsin; anti-streptolysin O; apolipoprotein A-I; apolipoprotein A-II; apolipoprotein B; apolipoprotein C-II; apolipoprotein C-III; apolipoprotein E; ceruloplasmin; complement C3; complement C4; CRP; cystatin C; ferritin; haptoglobin; HbA1c; IgA; IgE; IgG; IgM; lipoprotein (a); microalbumin; myoglobin; rheumatoid factor; transferrin and transthyretin (prealbumin).

Women should have fertility MoT at 25 as a āwake up callā so they donāt leave it too late
Young women should be offered ‘fertility MoTs’ at 25 so that they don’t leave it too late to start a family, doctors have said.
The British Fertility Society has warned that many young women are unaware of how their ability to conceive declines with age and has called for fertility checks to be introduced by the NHS to act as a “wake up call”.
The warning is intended to highlight the risks associated with waiting too long to start a family, such as the heartache of later infertility and complications in pregnancy and child birth.
Professor Adam Balen, Chairman of the British Fertility Society is quoted in the national press as wanting to “put the family back into family planning”, and said that many women were far too optimistic about their biological clock, and that women do not have the control over their fertility that easy access to contraception has led them to believe.
Checks could indicate whether you are more likely to have problems, or start having problems, and could indicate key measures such as how many eggs a woman has left. Consultations could include diet and lifestyle advice such as stopping smoking, cutting back on alcohol and checks on obesity and anorexia, which can contribute to infertility.
The number of women in Northern Ireland aged 35-39 having babies has increased in line with current trends across the rest of the UK, with around a fifth of all babies in the UK now born to mothers over 35 as many women put off starting a family due to a pressure to develop careers. Professor Balen suggests that ideally young couples should be trying to start a family by the time they are in their late 20s, or early 30s. He said that young people need to be able to have the option of both developing careers and starting families, “not one to the exclusion of another”.
With the NHS focused on education to try to prevent pregnancy, rather than encourage it, and a cut back on providing fertility treatments for couples struggling to conceive, it has become more and more common for people to self-fund fertility tests and treatments.
Jenny Dobbs, a leading fertility expert at Randox Health Clinics suggests that a fertility test early and regularly, would help couples who are trying for a family:
“Around one in six couples in Northern Ireland have difficulty conceiving, and this is not always down to a problem with the sperm, eggs and reproductive organs. A fertility health check can be life changing for a couple who are trying for a baby, or for women who want to understand more about their current fertility levels.
Randox Health takes a unique approach to fertility through comprehensive personalised blood testing for both men and women. Highly advanced assessments, or MoTs, are designed to identify the earliest signs of illness and work with clients to prevent disease in your future, which is very important for preserving your fertility and making healthy babies.”
BBC Investigation: ‘Taking legal highs is like playing russian roulette with your life’
A ground-breaking undercover investigation has exposed the deadly world of legal highs, the latest drug craze sweeping the UK and causing devastation to families and communities across the country.
An investigative team from the BBC followed the journey of these dangerous and highly addictive substances from source to sale and used secret filming to reveal that legal substances bought in the UK’s high streets pose a hazardous and lethal risk.
During the hour-long programme this evening on BBC Scotland, journalists shine a spotlight on the growing legal high epidemic, where synthetic drugs are designed to mimic the effects of illegal drugs such as cannabis, ecstasy and cocaine.
The team enlisted the help of Randox Testing Services, to further investigate the make-up of these drugs, which contain a cocktail of chemical ingredients that suppliers continually tweak to evade the law.
But the legality of these ‘highs’ in no way makes the drugs any safer. The disturbing test results show that legal highs bought in the UK contain a poisonous mixture of synthetic cannabinoids which have as strong an effect as illegal drugs, such as LSD or Amphetamines, and in some cases even stronger.
Sadly, the statistics correspond, as Government figures show that in just three short years the number of deaths in the UK linked to legal highs grew from 12 in 2009, to 97 in 2012.
It is a growing problem that Dr. Mark Piper, Head of Toxicology at Randox Testing Services, is all too familiar with:
“It’s very much back-room and underground chemistry that’s behind all this. You don’t know what’s in them and what quantities of chemicals are used, and therefore how much to take. These substances were not even designed to be used on humans, so in taking them you are playing Russian roulette with your life.”
Piper added; “In supporting the fantastic investigative team from the BBC we are glad to assist in highlighting this growing epidemic which has had shattering effects on families and communities across the UK.”
The intense rise in prevalence of legal highs and their catastrophic effects has sparked the debate of a controversial Psychoactive Substances Bill, which potentially will implement a blanket ban on the production, distribution, sale and supply of any substance defined as having a ‘psychoactive effect’.
This BBC Scotland documentary will air tonight, Monday, 5th October 2015, on BBC One Scotland at 9p.m.
Protect your family from early heart disease with a simple blood test
On World Heart Day 2015, Randox Laboratories unveiled a rapid, highly accurate diagnostic test to identify individuals with familial hypercholesterolemia (FH), a common disorder that is passed from parents to their children. FH is often called the ‘silent killer’ as it is characterised by dangerously high levels of cholesterol, leading to early onset cardiovascular disease. The good news is that if diagnosed, FH can be effectively treated; the even better news this National Cholesterol Month is that this new test has made diagnosis across the UK much simpler.
Thousands of families in the UK are affected by FH, as not only is heart disease the number one killer across the globe, there is a 50:50 chance that a parent with FH will pass it onto their children. The condition can lead to higher risk of a heart attack in men before the age of 50, or before the age of 60 in women.
A common disease, at least 1 in every 500 people in the UK are living with FH, although new international research suggests that 1 in every 200 people could be affected, which would mean as many as 300,000 people in the UK. Worryingly, it is substantially underdiagnosed and less than 12% of people with FH in the UK are aware that they have this potentially life-threatening condition.
The current recommended screening techniques are costly and time consuming, limiting the number of individuals who benefit from a timely diagnosis. Under NHS guidelines, when a person is found to have FH, their closest blood relatives should get tested too – including children before the age of 10. The new test allows definitive diagnosis within one day, rather than the usual weeks or even months for current tests, removing unnecessary anxiety and allowing people to take immediate action before it’s too late.
The new molecular test that has been developed by Randox Laboratories in Crumlin, Northern Ireland, in partnership with the Belfast Health and Social Care Trust, enables detection of the 40 most common genetic mutations that cause FH in the UK, with results available in just three hours. With early and appropriate treatment, such as adopting a healthy lifestyle and taking cholesterol-lowering medication, risk of heart disease can be significantly reduced so that someone with FH can live as long as a person who doesn’t have the condition.
Professor John Chapman, Past- President of the European Atherosclerosis Society, which promotes study into the causes of accelerated atherosclerosis and cardiovascular disease, has welcomed the new test for suspected cases of FH:
“FH is a serious condition for those with a family history of accelerated atherosclerosis and premature cardiovascular disease. With this information, preventative measures including diet, lifestyle and lipid lowering drugs can be successfully introduced. Indeed, early identification and prevention can significantly benefit all family members potentially with this condition. In fact, we are entering an exciting time in the treatment of those with cardiovascular disease as new and highly effective drugs for lipid management are becoming available.”
The test, which is available through Randox Health Clinics, has been adopted by medical professionals within the NHS, including Dr. Colin Graham, recently retired Consultant Clinical Scientist and former Head of the Regional Genetics Lab in the Belfast Health and Social Care Trust, who introduced the test within his Belfast Laboratory screen for suspected cases of FH:
“The launch of this new clinically available test is a key milestone in the detection and diagnosis of FH. Current FH diagnostic tests require a large volume of samples to be batched, leading to lengthy turnaround times of two to three months. With the new test, the turnaround time is dramatically reduced, enabling more rapid patient diagnosis.”
Dr. Graham also highlighted the importance of improving detection rates through the screening of wider patient populations:
“This new test has the potential to enable FH screening to become routine in the clinical setting for improved detection and earlier identification of familial cases.”
Dr. Peter FitzGerald, Managing Director of Randox Laboratories said:
“In the battle against cardiovascular disease, people with FH are on the front line. On World Heart Day it is important to raise awareness of FH as many people do not even know that they and their family members have this life-threatening condition. There is so much that can be done to support families with FH and with this readily available and much-needed test, detecting and treating entire families with FH is now possible.”

Randox calls for patients and prescribers to āresist and desistā antibiotic use
- UK-based diagnostics firm supporting call for responsible use of antibiotics in conjunction with European and International Antibiotics Awareness initiatives
- New molecular diagnostic multiplex assays hold the key to first-time, accurate diagnosis of infectious diseases
- Assays have the power to diagnose primary, secondary and asymptomatic co-infections to inform appropriate antibiotic prescribing
UK-based diagnostics company, Randox Laboratories, is supporting the call for patients and prescribers to ‘resist and desist’ antibiotic use in the fight against antimicrobial resistance this European Antibiotics Awareness Day. Coinciding with international awareness weeks in Australia, Canada and the USA, the concerted efforts of health authorities around the world to curb the spread of antimicrobial resistance is testimony to the global reach of the issue.
Now declared a ‘major threat’ by the World Health Organisation, Randox has been working at the forefront of this global challenge to deliver effective diagnostic solutions to arm against this growing problem. Developed over two decades of research and an investment of £200m, Randox’s innovative Biochip Array Technology (BAT) is the latest weapon in the fight against antimicrobial resistance, with the ability to simultaneously detect multiple pathogens in a single test for rapid and accurate diagnosis.
Randox’s range of molecular assays within infectious disease enable the detection of primary, secondary and asymptomatic co-infections for a more comprehensive understanding of the drivers of infection in individual patients. The Randox STI Multiplex Array simultaneously detects up to 10 pathogens from a single patient sample, whilst the Randox Respiratory Multiplex Array rapidly screens for 22 bacterial and viral upper and lower respiratory tract infections, with same day result reporting, for rapid diagnosis.
As Randox Managing Director Dr Peter FitzGerald CBE FREng explains, screening for all potential pathogens in infectious disease is vital in ensuring accurate diagnoses can be made; “Even after a confirmed diagnosis, many patients who haven’t been tested for a wider range of pathogens may harbour co-infections, impeding the effectiveness of therapeutic treatment and prolonging exposure to infection.
“Through a more comprehensive screening strategy at initial presentation, a complete patient profile can be obtained which will give clinicians greater understanding of the working of the disease and allow them to diagnose and prescribe correctly, ruling in or out the need for antibiotics, and helping to control their appropriate use.”
Antibiotic resistance has largely been fuelled by patient and prescriber overreliance on using antibiotics to treat disease. Once considered to be ‘magic bullets’ for curing infections, antibiotics are now firing blanks as they become ineffective against many common and treatable infectious diseases, such as the sexually transmitted infection, Neisseria gonorrhoeae, and respiratory tract infections such as staphylococcus aureus and streptococcus pneumoniae, which have been shown to be acquiring increasing levels of resistance to antibiotic treatment.
“First-time, accurate diagnosis of infection through molecular testing is key to treating infections correctly. The availability of these assays provides a powerful weapon in the fight against antimicrobial resistance and we would encourage health providers around the world to utilise this technology to help curb the spread of the problem.”
