International Day of Women and Girls in Science!
International Day of Women and Girls in Science!
On Saturday 11th February, we are celebrating International day of Women and girls in Science! This day is an opportunity to celebrate and promote equal access to science for women and girls.
Ahead of the 11th, we have interviewed five influential Women who fulfil STEM based roles across Randox Laboratories. They have shared their experiences and thoughts on Women and girls in the science industry.
Our fifth interview is with Marketing Manager, Lynsey Adams.
Why did you pursue a career in STEM?
I have always been interested in biology and what makes us unique. For that reason, I chose to study Genetics at Queens University Belfast. I have been lucky enough to work in the life sciences industry ever since.
What is your role in Randox and how long have you worked in the company for?
When I first came to Randox 15 years ago, I started off in Technical Support. I then progressed into the Marketing department and worked my way up to where I am today, to be the Head of Marketing. My role predominantly involves Marketing our scientific product ranges as well as B2C product offerings and sponsorships. Having a background in science has helped me to excel in my Marketing role and I am fortunate to be able to have the opportunity to do both the things that I enjoy and am passionate about.
What change have you seen for women in science over the years?
There has been an increase of women in STEM in general, whether that be more females studying STEM related subjects at university or exploring a career in STEM. Throughout the years, I have been privileged to work with so many females in managerial and authoritative roles within Randox.
Have you found it harder or any different going into your career in science as a woman?
Throughout the years I have been fortunate enough to have female teachers and lecturers provide crucial STEM related education who encourage females to pursue a career in STEM. During my working career I have experienced the same opportunities as other colleagues and seen an increase in women exceling in science.
How do you think we can encourage more women to go into the science industry?
Awareness of the varied career paths available within STEM related industries would be beneficial. The availability of work experience, placement, apprenticeship and graduate programmes like those offered at Randox helps to expose both males and females to the many exciting opportunities in the field.
If you have one piece of advice as a woman starting out the STEM industry, what would it be?
STEM is an equal playing field, so have confidence in your own ability and intelligence to get to where you want to be.

Celebrating World Antimicrobial Awareness week!
It’s World Antimicrobial Awareness week!
Antimicrobial resistance occurs when bacteria, viruses, fungi, and parasites resist the effects of medications, making common infections harder to treat and increasing the risk of disease spread, severe illness and death. As a result of drug resistance, antibiotics and other antimicrobial medicines become ineffective and infections become increasingly difficult or impossible to treat.
Randox want to take part in the global campaign that is celebrated annually to improve awareness and understanding of Antimicrobial. We have interviewed one of our Molecular specialists, Dr Dwaine Vance on how our revolutionary Randox products aid in the fight against AMR.
We are urging the public to help raise awareness of antimicrobial resistance. Randox is committed to the ongoing development of products and services as well as our research into numerous disease areas to improve health worldwide.

Celebrating World Diabetes Day 2022!
Celebrating World Diabetes Day, 14th November 2022!
Diabetes is a serious medical condition that causes blood glucose (sugar) levels to become too high. This can cause complications such as heart disease, stroke, kidney problems or nerve damage if not treated.
Although there is no cure for Diabetes, the condition can be controlled and monitored.
There are three main types of diabetes, type one, type two and gestational diabetes. The former two are lifelong and can cause life threatening complications if not monitored effectively.
Type one diabetes is when the body can’t make insulin, which is thought to be caused by an autoimmune reaction. In the UK, around 8% of the population have type one.
Type two diabetes is generally caused from lifestyle, when the pancreas doesn’t work properly and can’t keep your blood sugar levels from rising. Type two represents around 90% of people with diabetes in the UK.
Gestational diabetes Mellitus (GDM) is a form of diabetes that appears in pregnancy, characterised by high blood sugar due to the hormones produced in pregnancy. In the UK, around 5% of pregnant women are diagnosed every year.
Globally, Diabetes affects more than 415 million people, with type 2 being the most common.
People with T1D have an estimated 50% risk of developing Chronic Kidney Disease over their lifetime. CKD can progress to kidney failure, requiring dialysis or a kidney transplant. Taking a personalized approach to kidney disease screening for people with type 1 diabetes (T1D) may reduce the time that chronic kidney disease (CKD) goes undetected, according to a new analysis performed by the Epidemiology of Diabetes Interventions and Complications study group.
World Diabetes Day aims to increase visibility around the condition and can help sufferers feel less alone. Charities such as Diabetes UK also use the day to help promote awareness and information around the condition to help get people diagnosed earlier through campaigns such as #RewriteTheStory.
Randox reagents cover a spectrum of laboratory testing which can help monitor Diabetes and the effectiveness of management. This can help prevent serious complications which can become life threatening.
Diagnosis and Monitoring
Fructosamine (Glycated Protein) has been identified as an early indicator of diabetic control compared to other markers such as HbA1c. HbA1c represents the average blood glucose levels for the previous 2-3 months, conversely fructosamine reflects average blood glucose levels of the previous 2-3 weeks. HbA1c levels may also be impacted by genetic, haematological and disease-related factors. The enzymatic Fructosamine method also offers improved specificity and reliability compared to conventional NBT-based methods and does not suffer from non-specific interferences unlike other commercially available Fructosamine assays.
Complications Monitoring – Ketoacidosis
D-3-Hydroxybutyrate (Ranbut) is the most sensitive ketone for the diagnosis of ketosis, in particular diabetic ketoacidosis (DKA) , because it represents approximately 80% of ketones present in blood during DKA. The nitroprusside method commonly used in semi-quantitative dipstick tests only detects acetone and acetoacetate making it less accurate.
Complications Monitoring – Renal Dysfunction
Cystatin C is extremely sensitive to very small changes in GFR and has been identified as a strong predictor of clinical outcomes associated with chronic kidney disease (CKD). Cystatin C doesn’t have a ‘blind area’ like creatinine. Up to 50% of renal function may be lost before significant creatinine elevation occurs. NICE guidelines recommend cystatin C testing due to its higher specificity for significant disease outcomes.

Acute Kidney Injury
Acute Kidney Injury
–
Rapid Renal Injury Detection
Multiplex Detection of Acute Kidney Injury from a Single Sample
- Simultaneous and quantitative detection of multiple kidney function markers from a single patient sample for complete patient profiling
- Identify early stage renal impairment and ensure earlier intervention. Widely used in drug-related renal clinical trials
- Unique combination of analytes ensures better sensitivity and accuracy compared to traditional serum creatinine measurement
- The Randox AKI array measures four qualified FDA urine markers from one sample
- Multiplex testing better captures reduced renal function, as each biomarker reflects different mechanisms that result in similar injury outputs
- Utilising patented Biochip Technology, the Randox AKI array is currently available on the Evidence Investigator
Acute kidney injury (AKI) is currently diagnosed using serum creatinine as recommended by the KDIGO guidelines. Serum creatinine however, has poor sensitivity and specificity for AKI lagging behind both renal injury and recovery. There is an immediate need for more sensitive biomarkers to enables earlier identification of AKI, monitor drug toxicity and identify patients at an increased risk of CKD, end-stage renal disease or long-term kidney dialysis.
The National Institute for Health and Care Excellence (NICE) has highlighted that is important that patients are assessed for AKI on admission to hospital or transfer, monitored for AKI throughout their stay and AKI is managed appropriately if it develops.
Utilising patented Biochip Technology, the Randox Acute Kidney Injury (AKI) array simultaneously tests for four novel biomarkers delivering early diagnosis and monitoring of treatment efficacy It may also help you conduct safer and faster clinical trials.
Randox Acute Kidney Injury (AKI) Array (4-plex)
This marker is highly upregulated in kidney tubule cells following nephrotoxic injury severe enough to result in acute renal failure, acute tubular necrosis or acute tubulo-interstitial nephropathy.
Due to its small size and basic pH, Cystatin C is freely filtered by the glomerulus. It is then reabsorbed by tubular epithelial cells and subsequently metabolized. Accumulation of Cystatin C in urine is specific for tubular kidney damage and suggests reduced reabsorption at the proximal tubules as a result of toxicant-induced kidney injury.
Expression of Clusterin is upregulated following a variety of renal injuries and is detectable in urine following acute kidney injury induced by administration of nephrotoxic agents. This occurs before the profound renal transformations that give rise to changes in creatinine and BUN.
KIM-1 is a 30kDa type 1 transmembrane glycoprotein found on actvated CD4+ T cells. It is undetectable in healthy kidney tissue but is expressed at very high levels in proximal tubule epithelial cells in the kidney after toxic injury.
The Evidence Investigator
Meet the Evidence Investigator
The Randox AKI array has been developed for the Evidence Investigator, a semi-automated benchtop immunoassay analyser.
The AKI array would improve patient risk stratification whilst monitoring the effectiveness of treatments & drug toxicity by simultaneously and quantitatively detecting multiple urine biomarkers of kidney damage-related analytes from a single sample.

Rare Disease Day: 28th February 2019
28th February 2019
Rare Disease Day: 28th February 2019
Rare Disease Day raises awareness of rare diseases and how patients’ lives are affected. Many rare diseases remain incurable and many go undiagnosed. 1 in 20 people will live with a rare disease at some point in their life and this is why it is so important to raise awareness.1
What is a rare disease?
There is no single definition for a rare disease, as many countries identify them differently. In the United States, the Rare Diseases Act of 2002 defines a rare disease by its prevalence: “any disease or condition that affects fewer than 200,000 people in the United States”. However, the EU defines a rare disease as a condition that affects less than 5 in 10,000 of the population. There are approximately 7000 rare diseases and disorders and 50% of people affected by rare diseases are children.2,3
Hyperlipoproteinemia type III
This rare disease day, Randox will be raising awareness of hyperlipoproteinemia type III. Hyperlipoproteinemia type III, also known as dysbetalipoproteinemia or broad beta disease, is a rare genetic disorder characterised by improper breakdown of lipids, specifically cholesterol and triglycerides. The condition is caused by mutations in the Apo-E gene, however the inheritance of this condition is complicated due to the development of symptoms having to be triggered by a secondary factor to raise lipid levels. These factors include diabetes, obesity or hypothyroidism.
It is unknown exactly what the prevalence of the condition is, but it is estimated to affect approximately 1 in 5,000 – 10,000 of the general population and it has been found that it affects males more often than females, with women rarely being affected until after menopause.4,5
Figure A. Example of cholesterol and lipid build-up [6]
Symptoms
Symptoms for hyperlipoproteinemia type III will vary for each individual and some people may even be asymptomatic. The most common symptom is the development of xanthomas which are deposits of fatty material, the lipids, in the skin and underlying tissue. Xanthomas may appear on the palms of the hands, eyelids, soles of the feet or on the tendons of the knees and elbows.
> Chest pain or other signs of coronary artery disease
> Cramps in the calves when walking
> Sores on toes
> Stroke-like symptoms such as trouble speaking, dropping on one side of the face, weakness in an arm or a leg and a loss of balance6
Complications can arise if the condition is left untreated and these can include: myocardial infarction, ischemic stroke, peripheral vascular disease, intermittent claudication and gangrene of the lower extremities.7
Diagnosis
Although there is no specific diagnostic test for hyperlipoproteinemia type III, diagnosis is based on clinical evaluation and identification of symptoms. Research has indicated that an algorithm comprising a number of dysbetalipoproteinemia indices may be helpful in the diagnosis of the disease. These include:
> Low apolipoprotein B to total cholesterol ratio
> Elevated levels of triglycerides
> Elevated levels of total cholesterol8
Managing the condition
The condition cannot be cured but treatment is to control conditions such as obesity, hypothyroidism and diabetes. Most patients will go through dietary therapy to control their intake of cholesterol and saturated fat. This prevents xanthomas, high levels of lipids in the blood, exercise will also help to lower lipid levels. However, dietary changes may not be effective for some individuals and this is where drugs may be used to lower lipid levels instead.
How Randox can Help
Randox offer a range of routine and niche assays within the lipid testing panel to monitor lipid levels and to identify associated complications. Some of these tests include:
Apolipoprotein B
The Randox Apolipoprotein B tests utilises an immunoturbidimetric method, offers a wide measuring range and is available liquid ready-to-use for convenience and ease of use.
Total Cholesterol
The Randox Total Cholesterol test utilises the CHOD-PAP method and offers an extensive measuring range with a wide range of kits available to suit a wide range of laboratory sizes.
Triglycerides
The Randox Triglycerides test utilises the GPO-PAP method while offering an extensive measuring range with both liquid and lyophilised formats available offering choice and flexibility.

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.

Obesity and Kidney Disease: What is the Connection?
30th January 2019
Obesity and Kidney Disease: What is the Connection?
The month of January has forever been the month of resolutions with many choosing to ditch the sweets and join the gym. However, for many these efforts are limited to January and bad habits are quick to remerge. Obesity has been a burden on the health service for many years with the problem, like many people’s waist lines, only continuing to expand.
Recent findings have shown that this problem is no longer just increasing in developed countries but also in developing countries. In fact, worldwide obesity has tripled since 1975. In 2016, more than 1.9 million adults were classed as overweight, of which over 650 million were obese.1 These are shocking statistics for a condition that is preventable. As a global concern, it is important to assess all the potential risks of this problem.
The most common diseases associated with obesity are cardiovascular disease (CVD) and diabetes. However, the associated risks are much greater than this. Being overweight may also increase the risk of certain types of cancer, sleep apnea, osteoarthritis, fatty liver disease and kidney disease.2
Obesity is now recognised as a potent risk factor for the development of renal disease.3 Excess weight has a direct impact on the development and progression of chronic kidney disease (CKD). Globally, the prevalence of diabetic kidney disease rose by 39.5% between 2005 and 2015, coinciding with the increased CKD prevalence.4 In obese individuals, the kidneys have to work harder, filtering more blood than normal to meet the metabolic demands of increased body weight, increasing the risk of kidney disease.
The traditional diagnostic test for renal impairment is creatinine. This test is carried out through the measurement of creatinine levels in the blood to assess the kidneys ability to clear creatinine from the body. This is called the creatinine clearance rate which helps to estimate the glomerular filtration rate (GFR), which is the rate of blood flow through the kidneys.5
Problems arise when using creatinine for CKD testing as a number of factors need to be taken into consideration including age, gender, ethnicity and muscle mass. For this reason, black men and women exhibit higher creatinine levels than white men and women, raising concern over the accuracy of this test for certain patient groups.6 In addition, serum creatinine is not an adequate screening test for renal impairment in the elderly due to their decreased muscle mass.7
The main disadvantage of using creatinine to screen for renal impairment is that up to 50% of renal function can be lost before significant creatinine levels become detectable as creatinine is insensitive to small changes in GFR. Consequently, treatment is not provided at the appropriate time which can be fatal, therefore, an earlier and more sensitive marker for renal function is vital.8
These disadvantages have not only been highlighted in research but also by the national institute for health and care excellence (NICE). NICE updated the classification of CKD in 2004 to include the albumin: creatinine ratio (ACR). They split chronic kidney disease patients into categories based on GFR and ACR. Figure 1 highlights the different categories and risk of adverse outcomes. NICE recommend using eGFR Cystatin C for people in the CKD G3aA1 and higher.9
Figure 1 Classification of Chronic Kidney Disease using GFR and ACR categories.9
Despite these suggestions, Creatinine is still being used for G3a1 and increasing risk levels.
The utility of cystatin C as a diagnostic biomarker for kidney disease has been documented to show superiority of traditional CKD tests. There is no ‘blind area’ making it very sensitive to small changes in GFR and capable of detecting early reductions. Furthermore, this marker is less influenced by diet or muscle mass and has proven to be a beneficial test in patients who are overweight.8
A number of studies support the statement: ‘Cystatin C levels are higher in overweight and obese patients’. This is important because when cystatin c levels are too high, it may suggest that the kidneys are not functioning properly. One study conducted, using a nationally representative sample of participants, found that overweight and obesity maintained a strong association with elevated serum cystatin C. This suggests that weight can affect the levels of cystatin C and therefore the likelihood of developing kidney disease.10
How Randox can Help
The Randox automated Latex Enhanced Immunoturbidimetric Cystatin C tests offers an improved method for assessing CKD risk, combined with a convenient format for routine clinical use, for the early assessment of at risk patients. Randox is currently one of the only diagnostic manufacturers who offer an automated biochemistry test for Cystatin C measurement, worldwide.

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.
High Performing and Unique Testing Menu
The RX series of specific protein assays assist in the diagnosis and evaluation of various conditions each with excellent sensitivity and limited inference levels. Randox manufacture immunoturbidimetric kits for the study of a wide range of specific proteins including unique products such as Apolipoprotein C-II, Apolipoprotein C-III, Apolipoprotein E, Cystatin C and Microalbumin.
Most recently the RX series welcomed the addition of Direct HbA1c to our testing panel, available to be run on the RX Daytona +, RX imola and RX modena. 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.

World Diabetes Day: The Biggest Burden on the NHS
Diabetes
Approximately 400,000 people in the UK are living with type 1 diabetes, with over 29,000 being children and young people [1]. Type 1 diabetes affects 96% of all children with diabetes in England and Wales, with incidences increasing by approximately 4% each year.
Globally, the UK has the fifth highest rate of type 1 diabetes diagnosis in children (aged up to 14) with 85% of these children having no family history of the condition. Whilst the condition isn’t fatal and can be managed, it cannot be cured. Type 1 diabetes increases the risk of developing other health problems such as heart disease, stroke, foot and circulation problems, sight problems including blindness, nerve damage and kidney problems. However, many of these related conditions are preventable and it is recommended to stabilise blood sugar levels, attend diabetes appointments regularly and complete a diabetes course to educate patients and family members and prevent the risk of further help complications[2].
Diabetes in children
Children under five are at the highest risk of developing diabetic ketoacidosis due to a late diagnosis and it is also thought to be due to of lack of public knowledge of the signs and symptoms attributed to type 1 diabetes. Such symptoms include:
- Frequent urination as the kidneys are trying to expel excess sugar in the blood, resulting in dehydration which leads to extreme thirst.
- Increased hunger or unexpected weight loss because the body is unable to attain enough energy from food
- Slow healing cuts as high blood sugar levels can affect blood flow which can cause nerve damage.
- Fatigue as the body is unable to convert sugar into energy
- Irritable behaviour combined with other symptoms can be a means of concern
Diabetes and the NHS
Diabetes costs the NHS approximately £9.8 billion per year, an estimate of 10% of total expenditures. Hospital admissions of children and young people with diabetes presents a considerable burden on themselves, their families and the NHS. It is estimated that approximately 80% of these cases are potentially avoidable.
A report produced by the National Paediatric Diabetes Audit found that although the numbers of admissions didn’t significantly differ year to year, it highlighted differences in terms of socio-economic risk factors:
- Living in a deprived area increases the risk of hospital admissions which can be attributed to lack of education in the community about diabetic symptoms and the management of diabetes.
- Children below 5 years of age have a 35% increased risk of hospitalisation compared to those aged 5-9
- Females have a 33% increased risk of developing type 1 diabetes compared to males.
- Children with poor diabetes control have a twelve-fold increased risk of hospital admission
- Insulin pump users have a 27% increased risk of hospital admission compared to those who use insulin injections.

Prevention
There are campaigns in place to aid in the early diagnosis of type 1 diabetes which mainly focus on raising awareness of the signs and symptoms of diabetes. On this World Diabetes Day, it is important to know that it is not just simply the responsibility of the diabetic patient to prevent admission but the main responsibility lies with the diabetic teams that inform the families with children who are diagnosed with type 1 diabetes.
Paediatric diabetes teams should ensure that the families and the children receive structured education for self-management when diagnosed and throughout the illness. In doing so, the diabetic teams should implement blood ketone testing from diagnosis and utilise the nationally agreed hypoglycaemia management guidelines. It is also important that diabetic teams are fully aware of the patient characteristics associated with a greater risk of admission and that they use this knowledge to develop anti-admission strategies specifically tailored to the needs of each individual group.
Primary care practitioners should seek access to a specialist diabetic team who they can refer to when deciding if a patient requires admission to hospital. Furthermore, they should access blood glucose and ketone testing to identify patients at risk of diabetic ketoacidosis that require hospital admission.
How Randox can Help
Randox offer a range of assays to diagnosis and monitor diabetes and to monitor associated complications. Some of these tests are unique to Randox, including:
Fructosamine
The Randox fructosamine assay employs the enzymatic method which offers improved specificity and reliability compared to conventional NBT-based methods. The Randox enzymatic method does not suffer from non-specific interferences unlike other commercially available fructosamine assays.
D-3-Hydroxybutyrate (Ranbut)
The Randox D-3-Hydroxybutyrate (Ranbut) assay detects the most abundant and sensitive ketone in the body, D-3-Hydroxybutyrate. The Randox Ranbut assay is used for the diagnosis of ketosis, more specifically diabetic ketoacidosis. Other commercially available tests, such as the nitroprusside method, are less sensitive as they only detect acetone and acetoacetate, not D-3-Hydroxybutyrate.
Adiponectin
The Randox adiponectin assay is a biomarker in diabetes testing as adiponectin is a protein hormone responsible for regulating the metabolism of lipids and glucose and influences the body’s response to insulin. Adiponectin levels inversely correlates with abdominal visceral fat levels.
