A five-point calibrator with accuracy-based assigned target values (in nmol/l) is available, accurately reflecting the heterogeneity of the apo(a) isoforms.
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.
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.
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.
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.
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.
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.

Acetaminophen is a commonly used medicine for pain-relief. During cold and flu season, it is common to resort to pain-relief medicines to relieve headaches, and ache and pain symptoms associated with a cold or flu as there is no cure. However, the therapeutic range for acetaminophen is 10-30 mg/l, which is small and very easy to go over. During cold and flu season, it is important to monitor the amount of paracetamol entering your body as acetaminophen is more dangerous than suspected. At therapeutic levels, acetaminophen does not produce any adverse effects, however, long-term treatment, prolonged use, and taking a few more than the recommended dose can be severely damaging and fatal. Accidental acetaminophen overdose took the lives of 1,500 people in the U.S between 2001 and 2010. The Randox Acetaminophen assay is used to determine the concentration levels of acetaminophen in the blood to determine if an overdose has taken place.
It is commonly recognised that acetaminophen overdose causes hepatotoxicity, but it is less commonly recognised that it can also cause nephrotoxicity in less than 2% of patients. Nephrotoxicity is toxicity of the kidneys and is often associated with a reduced amount of glutathione which is important for normal cellular metabolism in the kidneys. The Randox Glutathione Reductase assay is required for the regeneration of reduced glutathione. Glutathione is often discussed in association with the Randox Glutathione Peroxidase, which requires reduced glutathione for activation. Both Glutathione reagents are unique to Randox.
Acute renal failure due to acetaminophen manifests as acute tubular necrosis, which can occur alone or in combination with hepatic necrosis. Nephrotoxicity can also occur when the therapeutic levels of acetaminophen are not exceeded. This most commonly occurs when acetaminophen is taken in combination with alcohol. Upon testing acetaminophen levels and the results fall within the therapeutic range, the Randox Ethanol assay can test alcohol levels to determine if a combination of alcohol and acetaminophen caused nephrotoxicity. Renal impairment may be more common than previously suspected as acute renal failure occurs in 10-40% of patients with severe hepatic necrosis. Upon testing acetaminophen to determine toxicity, Randox also offer the following renal tests to test for nephrotoxicity:

So far in our inflammatory biomarker series, we have considered the clinical significance of measuring rheumatoid factor (RF) and C-reactive protein (CRP) to detect inflammation. Inflammation, either chronic or acute, is the body’s immune response to protect against harmful stimuli such as damaged cells, irritants or pathogens and can be present in a range of diseases and conditions.1 Measuring inflammatory biomarkers can assist clinicians in the identification of a particular disease or can provide a marker of treatment response. In this blog, we consider the role of antioxidants and identify relevant biomarkers which may be linked to inflammatory states.
What is an antioxidant?
An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that produces free radicals, which are groups of very reactive molecules that can interrupt important cellular processes. Antioxidants are commonly referenced with regards to food, however antioxidants are also found in the body in the form of enzymes. Their purpose is to protect against the effects of oxidative stress to reduce damage from free radicals.
What is the link between antioxidants and inflammation?
Oxidative stress and the inflammation associated with it are the cause of most human disease. This would suggest that free radicals are implicated in many disease states for example rheumatoid arthritis, asthma, stroke, or cancer. Therefore antioxidants are important to protect against oxidative damage, thus reducing the risk of inflammation. There are a number of antioxidants which play a protective role the body, such as ferritin, superoxide dismutase, transferrin, uric acid and glutathione reductase.
Ferritin is responsible for storing iron and releasing it when required. Ordinarily, ferritin is found inside blood cells with only a small amount circulating in the blood. Ferritin is clinically significant at both high and low levels. Low levels of ferritin can highlight an iron deficiency which causes anaemia. Whereas elevated levels of ferritin can be a result of conditions such as rheumatoid arthritis, haemochromatosis, liver disease, metabolic syndrome, type 2 diabetes and renal failure.2 As ferritin is an acute phase reactant, levels will be elevated in any inflammatory state within the body.3
Transferrin is a protein that is responsible for binding and transporting iron in the blood. Transferrin acts as a preventative antioxidant as it binds with free iron, removing it from the bloodstream. This is a critical function, as free iron can stimulate the production of harmful free radicals. As transferrin is a negative acute phase protein, lower levels are associated with inflammatory conditions.7
Superoxide is a by-product of oxygen metabolism and is one of the most damaging free radicals in the body as it can cause cell damage. Superoxide Dismutase (SOD) is an enzyme which catalyses the breakdown of superoxide into a less damaging oxygen or hydrogen peroxide. Therefore SOD preforms a vital defensive function to reduce oxidative stress.4 Extensive research exists which links oxidative stress to chronic inflammation, which can be a contributing factor to diabetes, arthritis, cardiovascular disease and cancer.5 Therefore if levels of superoxide dismutase are low, patients are at risk inflammation, for example, SOD levels are significantly less in rheumatoid arthritis patients.6
Glutathione reductase is found in red blood cells and plays a key role in maintaining cell function and preventing oxidative stress in human cells. Reduced levels of glutathione reductase can contribute to the prevalence of inflammatory states, suggesting that adequate levels of glutathione reductase are essential for optimal function of the immune system. 7, 8
Uric acid is a waste product produced when the body breaks down chemical compounds called purines. It is a scavenging antioxidant that acts by inactivating free radicals. Elevated levels of uric acid is commonly associated with gout, a type of arthritis which is caused when crystals of sodium urate form inside joints causing rapid and painful inflammation.9 Other research has indicated that elevated levels of uric acid is associated with increased risk of cardiovascular disease.
Total Antioxidant Status (TAS)
TAS is a measurement of antioxidant function rather than quantity and considers the cumulative effect of all antioxidants present. The antioxidant defence system has many components, and a deficiency in any of these components can cause a reduction in the overall antioxidant status of an individual.10 Reduction in total antioxidant status has been implicated in several disease states including cancer, CVD, Arthritis and Alzheimer’s disease.
As demonstrated above, different types of antioxidants can help reduce different types of inflammation. Antioxidant tests can be requested from any doctor, who may also review dietary intake, investigate any symptoms and advise if testing is required. If antioxidant levels are found to be inadequate, improving them can be easily done through dietary changes, and can help reduce a body’s overall inflammation.
