What is Haptoglobin assay used for?
Haptoglobin measurements are used in the diagnosis of haemolytic anaemia and to distinguish it from other types of anaemia. In haemolytic anaemia, haptoglobin levels in the blood decrease significantly. Low levels however may also indicate red blood cell destruction due to sickle cell anaemia or thalassemia. In certain cases of liver disease haptoglobin levels may also be low, as the liver cannot manufacture normal levels of the protein.
As an acute phase reactant haptoglobin levels in the blood are significantly increased in response to infection, inflammation, burns, surgery and trauma. However, haptoglobin is not generally used to diagnose or monitor these conditions.

What is the Complement C4 assay used for?
What is Complement C4?
The complement system is one of the major mechanisms of innate immunology consisting of more than 30 plasma and membrane-associated serum proteins which evokes cytolytic immune responses to pathogens, including viruses, bacteria, chemical tissue damage and anything that is classified as foreign to the body. The complement system can be activated through three major pathways: classical, lectin or alternative. Once activated, reactions occur for antibody opsonisation (the process by which a phagocyte marks a pathogen for ingestion and elimination) to fight against the foreign bodies. Activation can also occur when the body produces antibodies for its own tissues that it views as being foreign, which is known as an autoimmune disorder.
During the activation process, Complement C4 splits down into C4b and C4a (peptide). C4b acts as an opsonin and remains bound to the complex at the surface of the pathogen which activates the next step of the process. The small peptide, C4a diffuses away and acts as a chemotactic factor and an inflammatory paracrine.
The Randox Complement C4 assay is used for the quantitative in vitro determination of complement C4 concentration in serum. The Randox Complement C4 assay allows for the diagnosis and monitoring of autoimmune disorders associated with abnormal levels of complement C4 including lupus and rheumatoid arthritis (RA). Higher than normal results may be indicative of cancer or ulcerative whereas lower than normal results may be indicative of lupus, hepatitis, or cirrhosis.
Cell-bound levels of processed complement activation products, especially E-C4d (erythrocyte-bound C4) is a biomarker in the diagnosis and monitoring of systematic lupus erythematous (SLE). For more information on SLE, please click here.

What is Rheumatoid Factor assay used for?
Research has shown that both environmental and genetic factors can affect the production of RF with various biological properties. Although they may be found in all immunoglobulin classes, the RF most frequently detected is the IgM type; present in about 75% of adult patients with RA and about 10% of children with juvenile RA. RF have also been observed in the serum of patients with lupus erythematosus, hepatitis, liver cirrhosis, syphilis and various other conditions; but the RF titre is much lower than in RA.

What is HbA1c assay used for?
The concentration of HbA1c in the blood of diabetic patients increases with rising blood glucose levels and is representative of the mean blood glucose level over the preceding six to eight weeks. HbA1c can therefore be described as a long term indicator of diabetic control unlike blood glucose which is only a short term indicator of diabetic control.
It is recommended that HbA1c levels are monitored every three to four months. In patients who have recently changed their therapy or in those who have gestational diabetes it may be beneficial to measure HbA1c levels more frequently, at two to four week intervals.

Free radicals / reactive oxygen species (ROS) are produced during normal cellular metabolism, however, can have harmful effects. Antioxidants are the first line of defence and are produced by the body to neutralise the harmful effects of ROS, preventing cellular damage 1,2, 3. Measuring total antioxidant status (TAS) can provide information on an individual’s overall antioxidant status, which may include antioxidants not yet recognised or not easily measured. The TAS of a sample is a quantitative measurement of the state of balance of the various components (exerting actions in different way) under specified reaction conditions 4.
Reduced levels of total antioxidant status (TAS) is indicative of oxidative stress and increased susceptibility to oxidative damage 5. Oxidative stress is an imbalance between the ROS and antioxidants in the body, favouring ROS 6. Oxidative stress is associated with several health conditions, including: chronic inflammation, neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease, cancer and CVD 7.

Diagnostic Uses
Glutathione peroxidase (GPx) is a reactive oxygen species (ROS), generated by bodily cells via mitochondrial and enzymatic sources. It is vital that GPx levels are reviewed as it can cause oxidative damage to membrane lipids, proteins and DNA. GPx is an intracellular antioxidant enzyme that enzymatically converts hydrogen peroxide to water (detoxification). Hydrogen peroxidase is vital for the maintenance of normal thiol redox-balance, mitochondrial function, and growth factor-mediated signal transduction. By converting hydrogen peroxidase to water, GPx aids in modulating these processes 1. GPx also contributes to cell signalling and oxidative protein folding 2.
Four of the eight glutathione peroxidases (GPx) are selenoproteins (containing the amino acid form of selenium, Sec) in humans, however, GPx6 is cysteine-containing in rodents, but a selenoprotein in humans, whereas the remaining GPx’s are cysteine containing. Glutathione peroxidase 4 (GPx4) is emerging as one of the most important seleoproteins in mammals and is one of the key regulators of ferroptosis, a form of regulated necrotic cell death 2.
GPx displays an inverse correlation with free radicals and consequently oxidative stress (OS). When GPx activity is reduced, antioxidant protection is impaired, resulting in oxidative damage to the membrane fatty acids and functional proteins, resulting in neurotoxic damage. Decreased GPx activity and OS is implicated in the incidence and progression of several health problems, including: cardiovascular disease (CVD), diabetes, atherosclerosis, neurodegenerative disorders and other chronic conditions 3.

Non-esterified fatty acids are important metabolites stored in adipose tissue. NEFA turnover is swift, with a plasma half – life of 2 to 4 minutes. The dominant source of NEFA is abdominal subcutaneous fat, with considerably less found in leg adipose tissue and a small proportion found in the intraabdominal adipose tissue. NEFA has been recognised as a vehicle by which triacylglycerol (TG) (stored in the adipose tissue) is transported to its sites of utilisation 1. NEFA has been identified as the major source for skeletal muscle during fasting stages and long periods between meals. Cross – sectional studies have consistently documented that circulating NEFA levels are proportional to body fat storage and demonstrated positive correlations between fasting NEFA levels and obesity, insulin resistance and glucose tolerance 2.
Non-esterified fatty acids concentrations are strongly associated with insulin resistance. In the fasting state, the resistance of adipose tissue to the antilipolytic effect of insulin causes the extensive release of NEFA into circulation. Consequently, elevated NEFA levels exacerbate insulin resistance through diminishing insulin – stimulated glucose intake into the skeletal muscle, directly affecting insulin signalling 3.

What is Urinary Protein assay used for?
Determination of Total Protein in urine and cerebrospinal fluid is valuable in the diagnosis of renal and central nervous system disorders respectively. Urinary protein elevations are commonly seen in the following conditions: strenuous exercise, fever and hypothermia, nephrosis and diabetic nephropathy and urinary tract infections. Determination of total protein in cerebrospinal fluid aids in the diagnosis of such conditions as meningitis, CNS tumours and cerebral haemorrhage.
