  • Superior Performance & Niche Assays
  • Risk Assessment using Randox Reagents
Lp(a)

The Randox Lp(a) assay is calibrated in nmol/l and traceable to the WHO/IFCC reference material (IFCC SRM 2B) and provides an acceptable bias compared with the Northwest Lipid Metabolism Diabetes Research Laboratory (NLMDRKL) gold standard. A five-point calibrator with accuracy-based assigned target values (in nmol/l) is available, accurately reflecting the heterogeneity of the apo(a) isoforms.

Bile Acids

The Randox bile acids test utilises an advanced enzyme cycling method which displays outstanding sensitivity and precision when compared to traditional enzymatic based tests. The Randox 5th Generation Bile Acids test is particularly useful in paediatrics where traditional bile acids tests are affected by haemolytic and lipaemic samples.

Bilirubin

A superior assay from Randox, the vanadate oxidation method offers several advantages over the diazo method, including less interference by haemolysis and lipaemia, which is particularly evident for infant and neonatal populations.

Adioponectin

Adiponectin has been identified as having pleiotropic functions widely associated with anti-atherogenic, anti-diabetic, cardioprotective and anti-inflammatory effects. Adiponectin levels inversely correlate with insulin levels, BMI, triglyceride levels, insulin resistance (IR), glucose, and most importantly, visceral fat accumulation.

sTfR

Soluble transferrin receptor (sTfR) is a marker of iron status. In iron deficiency anaemia, sTfR levels are significantly increased, however remain normal in the anaemia of inflammation. Consequently, sTfR measurement is useful in the differential diagnosis of microcytic anaemia.

Fructosamine

The Randox Fructosamine assay utilises 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.

Current Challenges

CVD
  • Cardiovascular Disease (CVD)

    CVD accounts for 45% of all deaths in europe and 37% of all deaths in the EU. Atherogenesis is a circulatory disease whereby atheromas are formed (plaque build-up) within the artery.  Plaque is a combination of cholesterol, fat, calcium, lipids and other substances within the blood stream.  As time progresses, the plaque hardens, narrowing the arteries.  This is known as atherosclerosis. Consequently, blood flow through the narrowed artery is reduced, limiting the supply of blood to vital organs and bodily tissues.  As atherogenesis can affect any artery within the body, different diseases may develop based on the artery that is affected.  Such diseases include: coronary heart/artery disease, carotid artery disease, peripheral artery disease and chronic kidney disease 2, 3, 4.

  • Type 2 Diabetes Mellitus (T2DM)

    425 million people are living with type 2 diabetes mellitus (T2DM) and 352 million are at risk of developing T2DM. T2DM is a serious condition whereby blood glucose levels are elevated (hyperglycaemia). T2DM is characterised by insulin resistance or insulin deficiency. T2DM is the most common form of diabetes, accounting for 90% of cases. The key to T2DM is control. Implementing lifestyle changes, oral medication and in more severe cases, insulin, a diabetic can take control of their disease, keeping glucose levels stable. When glucose levels are not monitored and controlled, associated complications may arise including: diabetic nephropathy, CVD and renal impairment 5, 6.

  • Chronic Kidney Disease (CKD)

    Worldwide 1/5 of men and 1/4 of women between 65 and 74 years of age have Chronic kidney disease (CKD). CKD is an umbrella term encompassing a wide range of renal conditions from commonly prevalent sub-clinical, asymptomatic to rare end-stage renal disease requiring dialysis or a transplant to sustain life. Kidney disease is ranked in stages from stage 1 (very mild damage) through to stage 5 (kidney failure) 7. Symptoms are commonly expressed in the later stages of renal impairment, however, at this point dangerous levels of fluid, electrolytes and waste products can build up inside the body. The aim of CKD treatment is to slow the progression of the disease, thus early intervention is vital 8.

Featured Reagent – sPLA₂-IIA

sPLA2-llA | Featured Reagent

1st April 2019

 

Clinical Significance

 

sPLA2-llA production of fatty acids and biologically active phospholipids plays an important role in platelet, monocyte, and endothelial activation, processes known to be critical steps in atherogenesis.1 Unlike traditional cardiac biomarkers used to predict adverse outcomes in patients with acute coronary syndrome (ACS), sPLA2-llA has been shown to act at multiple pathways involved in atherogenesis, from lipid oxidation to modulation of vascular & inflammatory cell activation and apoptosis.2

Did you know?

Cardiovascular disease (CVD) is the number one cause of death globally and more people die annually from CVD than from any other cause.3

Key observations through research has found that sPLA2-llA mediated modification of lipoproteins plays a role in the development of atherosclerosis. The surface of both low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) is surrounded by phosphatidylcholine (PC) a type of phospholipid which has been scientifically proven to serve as a good extracellular target for several isoforms of sPLA2-llA. sPLA2-llA works by hydrolysing these phospholipids resulting in the production of free fatty acids and lysophophatidylcholine (LPC) which can generate pro-inflammatory actions, accelerating atherosclerosis.1

Hydrolysis of LDL-C correlates with the production of the more atherogenic, small dense LDL cholesterol (sdLDL-C). The sPLA2-llA -processed low-density lipoprotein (LDL) contains a large amount of lysophospholipids and exhibit the property of “small-dense” or “modified” LDL, which facilitates foam cell formation from macrophages. Research has shown that high plasma levels of sdLDL-C  compared to less dense, larger LDL-C create a higher risk of coronary heart disease.

Cardiovascular Disease

 

Regular cardiovascular screening is important to ensure that cardiac risk factors are detected at the earliest possible stages. Cardiovascular disease (CVD) encompasses a number of diseases of the heart and blood vessels.  Four of the main types of CVD include: coronary heart disease (CHD), cerebrovascular disease (CVA), peripheral arterial disease (PAD) and aortic disease.  It is vital that at risk patients are diagnosed as quickly and efficiently as possible to ensure effective treatment plan implementation.4

The early diagnosis of CVD aids in reducing the risk of a secondary cardiovascular event and to ensure the patient receives appropriate treatment to prevent premature deaths. Early risk assessment is particularly important in people who are at a greater risk of CVD. This is evaluated through the identification of one or more risk factors including: hypertension, diabetes or hyperlipidaemia. 3 ,5

It is believed that by 2030, almost 23.6 million people will die from CVD, mainly CHD and CVA, and is projected to remain the single leading cause of death. This provides further confirmation that early diagnosis is vital to prevent and reduce the number of deaths attributed to CVD.3

Securing the future with in vitro diagnostic tests

The aim of Biomedical Science Day is to raise the public’s awareness of the importance of biomedical science and the vital role it plays in the world.  Randox are dedicated to improving healthcare worldwide through placing a major focus on research and development.  The Randox scientists work in pioneering research into a range of common illnesses such as cancer, cardiovascular disease and Alzheimer’s disease.

A recent blog from Doris-Ann Williams, the Chief Executive at BIVDA, explains how “increased funding is not enough to sustain the NHS” and how “we need to make better use of in vitro diagnostics to ensure a successful future”.

The National Health Service (NHS) is a publicly funded, primarily taxation, national healthcare system in the United Kingdom.  It was first set-up on July 5th, 1948 by Aneurin Bevan as he believed that everyone, regardless of wealth, should have access to good healthcare.  Whilst the NHS is an extremely important aspect of healthcare in the UK, in vitro diagnostics are the heart and soul of the healthcare system as healthcare professionals not only rely on blood tests to diagnose and treat patients, but also to rule out the different contributing causes to a disease state.  In vitro diagnostics also plays a key role in monitoring chronic disease states.  In vitro diagnostics can also aid in reducing hospital stays, reduce misdiagnosis and support patients in looking after their own health and to deliver personalised treatment plans.

The Randox scientists have developed several niche assays to improve patient diagnosis, monitor treatment and eliminate misdiagnosis.

Adiponectin

Adiponectin is a protein hormone secreted by adipocytes with anti-inflammatory and insulin-sensitising properties.  It plays an important role in a number of metabolic processes including glucose regulation and fatty acid oxidation.  Adiponectin levels are inversely correlated with abdominal visceral fat which have proven to be a strong predictor of several pathologies, including: metabolic syndrome, type 2 diabetes mellitus (T2DM), cancers and cardiovascular disease (CVD).  For more information on the importance of testing Adiponectin levels, check out our Adiponectin Whitepaper.

Cystatin C

Cystatin C is an early risk marker for renal impairment.  The most commonly run test for renal impairment is Creatinine.  Creatinine measurements have proven to be inadequate as certain factors must be taken into consideration, including age, gender, ethnicity etc.  The National Institute for Health and Care Excellence (NICE) have updated their guidelines, which now recommends Cystatin C as a more superior test for renal impairment due to its higher specificity for significant disease outcomes than those based on Creatinine.  For more information on the importance of testing Cystatin C levels, check out our Cystatin C Whitepaper.

Small-dense LDL Cholesterol (sdLDL-C)

LDL Cholesterol (LDL-C) consists of two parts: the large and buoyant LDL Cholesterol and the small and dense LDL Cholesterol.  Whilst all LDL-C transports triglycerides and cholesterol to bodily tissues, their atherogensis varies according to their size.  As sdLDL-C is small and dense, they can more readily permeate the arterial wall and are more susceptible to oxidation.  Research indicates that individuals with a predominance of sdLDL-C have a 3-fold increased risk of myocardial infarction.  It has been noted that sdLDL-C carries less Cholesterol than large LDL, therefore a patient with predominately sdLDL-C particle may require nearly 70% more sdLDL-C particles to carry the same amount of cholesterol as the patient with predominately LDL-C particles.  For more information on the importance of testing sdLDL-C levels, check out our sdLDL-C Whitepaper.

These three niche in vitro diagnostics tests developed by Randox scientists can aid in reducing NHS costs due to their higher performance compared to the traditional tests.  Randox are constantly striving to improve healthcare worldwide.
