What is Gamma GT assay used for?
Gamma-glutamyltransferase (GT) in serum originates primarily from the hepatobiliary system. Therefore GT is elevated in all forms of liver disease and has been shown to be more sensitive than alkaline phosphatase in detecting obstructive jaundice, cholangitis and cholecystitis. High levels of GT are also seen in patients with primary or secondary liver cancer. Increased levels are also observed in cases of alcohol abuse and in alcoholic liver cirrhosis. In patients receiving anticonvulsant drugs such as phenytoin and phenobarbital, increased levels of the enzyme in serum may reflect induction of new enzyme activity and the toxic effects of alcohol and other drugs on the microsomal structures in liver cells. GT is the most sensitive enzymatic indicator of hepatobiliary disease, and can be used in combination with other biochemical markers to discriminate between different types of hepatobiliary disease.

What is CO2 Total used for?
Carbon dioxide (CO2) is a metabolic waste product of cellular respiration. It is transported in the bloodstream to the lungs and expelled from the body. CO2 exists in the body in two forms: 90% exists as bicarbonate (HCO3) and the remaining exists as carbonic acid (H2CO3) or dissolved CO2. The kidneys and lungs are responsible for the regulation on CO2, H2CO3 and HCO3 in the blood.
What is the CO2 Total assay used for?
The Randox CO2 Total assay is used for the quantitative in vitro determination of CO2 in serum and plasma. It aids in diagnosing diseases associated with high and low levels of CO2 in the bloodstream.
Slightly elevated levels of CO2 do not have any serious consequences on the body, but overexposure to CO2 due to decreased alveolar ventilation or the inhalation of CO2 enriched air can cause serious implications in the body including: deterioration of respiratory functions due to respiratory acidosis and asphyxiation, cardiovascular effects due to low blood pressure and cardiac arrhythmia and nerve damage due to hypercapnia and acidemia.
For more information on the contrasting effects of hypoxia and hypercapnia, please click here.
High CO2 levels usually indicates that the lungs are not functioning properly and are unable to expel the required amount of CO2. During an acute illness, the levels of CO2 can increase suddenly, however, over time, some people are able to establish a new ‘baseline’ for CO2. An example of this is a person with stable chronic obstructive pulmonary disease (COPD) This means that the body is able to function with higher than normal levels of CO2.
There are some medical conditions and drugs that can cause low CO2 levels including: kidney disease as the kidneys are unable to carry out their functions, diabetic ketoacidosis due to the production of ketones resulting in reduced CO2 levels, hyperchloremic acidosis due to diarrhea, Addison’s disease, and metabolic acidosis due to chemical toxicity.

Physiological Significance
Zinc (ZN) is an essential trace element (micronutrient) and plays a vital role in several biological processes 1. ZN is released from food as free ions during digestion. Specific transport proteins facilitate the passage of ZN across cell membranes into circulation. 70% of circulatory ZN is bound to albumin 2. As ZN does not attain redox properties, it is capable of transportation around the biological systems without inducing oxidative damage, which can occur with other essential trace elements like copper 3.
ZN has a key role in growth, reproduction, sexual maturity and the immune system. ZN is vitally important in the functionality of >300 enzymes utilised in the stabilisation of DNA and gene expression 1. ZN can constitute strong, yet readily available flexible and exchangeable, complexes with organic molecules, enabling it to modify the three-dimensional structure of specific proteins, nucleic acids, and cellular membranes, thereby influencing the catalytic properties of many enzyme systems and intracellular signalling. ZN is associated with >50 metalloenzymes with a diverse range of functions and so ZN plays a central role in metabolism, differentiation and cellular growth 3.
Deficiency
Zinc deficiency has been identified as a malnutrition issue worldwide. ZN deficiency is more prevalent in areas of low animal consumption and high cereal consumption. It’s not that the diet is low in ZN but more so the bio-availability of ZN which plays a major role in its absorption. Phytic acid has been identified as the main inhibitor of ZN. Adolescents, children, infants, lactating women and pregnant women have increased requirements for ZN and so are at higher risk of zinc depletion. During growth periods, ZN deficiency causes growth failure. The organs most affected by ZN deficiency include: central nervous system, epidermal, gastrointestinal, immune, reproductive and skeletal systems 2.
Toxicity
As there are multiple sources of ZN in the environment, exposure to and toxicity from ZN are not uncommon. Case reports have documented zinc toxicity caused by: overuse of dietary supplements, inhalation from occupational sources, denture cream and ingestion of pennies, to which some of these cases had fatal outcomes 4.
It is believed that ZN toxicity from acute exposure differs significantly from chronic toxicity. In acute exposures, ingestions of ZN sulfate and concentrated ZN chloride will primarily result in gastrointestinal symptoms, such as haematemesis. Renal injury, liver necrosis, coagulopathy and even death have been reported following acute exposures 4.
Chronic exposure caused by excessive consumption of ZN, resulting in copper deficiency can lead to myelodysplastic syndrome, granulocytopenia and sideroblastic anaemia 4.

Diagnostic Uses
Ketosis is a metabolic process that occurs when the body switches from glucose to predominantly fat metabolism for energy production, this happens when carbohydrate availability reaches low levels. The metabolism of fatty acids in the liver results in the production of chemical by-products known as ketone bodies or ketones. Ketosis occurs when the body produces more ketones than the liver can process.
DKA is a serious complication of both Type I Diabetes Mellitus (T1DM), however can also affect individuals with T2DM. The condition is linked to insulin deficiency and occurs when glucose levels are consistently high and insulin levels are severely low. Due to this imbalance glucose builds up in the blood and the body responds by metabolising fat rather than glucose. DKA is usually one of the first indicators of T1DM.
Ketosis is not normally dangerous and is typical of ketogenic diets which are low in carbohydrates. Ketones however are poisonous when present in high levels leading to ketoacidosis, DKA for example if left untreated can cause damage to vital organs and in some instances may lead to a coma or death. DKA is commonly triggered by an illness, infection or missing insulin treatments.
The American Diabetes Association recommends testing for ketosis in diabetics when symptoms of ketoacidosis are present, when
glucose levels are consistently elevated, during pregnancy and if experiencing any illness. NICE also recommend monitoring ketones in patients with T1DM especially during periods of illness.
Semi-quantitative, nitroprusside-based methods remain common for the detection of ketones in the blood and urine of diabetic patients. The nitroprusside method is available in both tablet and reagent test strip form where urine or blood is applied, and a colour change observed. There are several limitations associated with Nitroprusside methods;
- Capable of detecting only acetone and acetoacetate, as such they lack sensitivity especially in early stages of DKA.
- The intensity of the colour change observed is subjective compared to quantitative methods like D-3-Hydroxybutyrate which can be used to monitor recovery and improvements to treatment.
- Several medications including Valproic Acid and Vitamin C can interfere with nitroprusside methods leading to false positive
results. - False negative results are common as the method does not detect the main ketone body – D-3-Hydroxybutyrate. As ketoacidosis improves and D-3-Hydroxybutyrate is converted to acetoacetate the result with urine dipsticks can appear positive despite the patient’s status improving by this stage.
- D-3-Hydroxybutyrate is a more reliable indicator of ketosis and DKA due to its superior stability when compared to acetone and
acetoacetate.
When the carbohydrate stores are significantly decreased, or the fatty acid concentration is increased, there is an upregulation of the ketogenic pathway and consequently, an increased production of ketone bodies. This is commonly observed in alcoholism, type I diabetes and starvation. Most organs, including the brain, can utilise ketones as its source of energy. The liver however, cannot utilise ketones, despite producing them, as the liver lacks the necessary enzyme ketoacyl-CoA transferase 1.
Ketosis is the presence of ketones. Whilst ketosis is not dangerous, if left untreated, especially in diabetes, ketoacidosis (high levels of ketones) develops 2.
In type 1 diabetes mellitus (T1DM), the body is unable to produce insulin resulting in bodily cells not receiving energy from glucose, causing the body to release hormones to breakdown fat for energy, producing ketones. If left untreated, diabetic ketoacidosis develops, a serious health condition. Diabetic ketoacidosis is commonly triggered by an illness, infection or missing insulin treatments 3.
There are three main ketones produced as a result of ketosis; D – 3 – Hydroxybutyrate, acetoacetate and acetone.
D-3-Hydroxybutyrate is the most abundant of the three accounting for 75% of total ketones in the body, it is later catabolised into acetoacetate and then into acetone. Due to the higher levels of D-3-Hydroxybutyrate, it is the more sensitive marker for the diagnosis of ketosis, in particular DKA.
Ketogenesis is a biochemical process whereby the body produces ketone bodies (acetone, acetoacetate, beta-hydroxybutyrate. As ketone bodies are water soluble, they do not require lipoproteins for transport 1.
In healthy humans, small amounts of ketones are continuously made for the body to use an energy. Ketone bodies increase in times of fasting and sleeping 1.

What is the Calcium assay used for?
What is calcium?
Calcium is the fifth most abundant element in the body. Most of it in the human adult is extracellular and 99% of it exists as crystalline hydroxyapatite in bones and teeth where it confers rigidity. It plays a major role in the mechanisms of nerve impulse transmission, muscular contraction and blood coagulation. Secretion from the parathyroid glands, thyroid C cells and pancreatic B cells is controlled by the extracellular ionised calcium concentration at the cell surface.
What is the calcium assay used for?
It is tested to diagnosis and monitor numerous conditions related to the heart, nerves, bones and kidneys.
Hypercalcemia can be the result of hyperparathyroidism (overactive parathyroid gland), cancer, carcinomas, vitamin D overdoses and are of diagnostic value in detecting chronic renal disease and acute pancreatic disease.
Hypocalcemia is associated with hypoparathyroidism (underactive parathyroid gland), vitamin D deficiency, calcium deficiency, kidney dysfunction and renal failure. For more information on risk factors for post-thyroidectomy hypocalcemia, please click here [external link].
The Randox Calcium assay is used for the quantitative in vitro determination of calcium concentration in serum, plasma and urine.

Homocysteine is a sulfur-containing amino acid produced by the intracellular demethylation of the essential amino acid, methionine. Homocysteine has three metabolic functions within the human body: firstly, to be remethylated into methionine; secondly, to enter the biosynthetic pathway of cysteine; and thirdly, to be released into the extracellular medium (blood and urine). The third metabolic function is the direct cause of elevated homocysteine concentrations in urine and plasma 1, 2.
Hyperhomocysteinemia (elevated levels of homocysteine) has been identified in numerous conditions and disease states including, cardiovascular disease (atherosclerosis and thrombosis), pregnancy complications, psoriasis, cognitive impairment in the elderly, mental disorders, neural tube defects and birth defects 1, 2.
Women with elevated levels of homocysteine have a 3-fold increased risk of CVD, whereas men have a 2-fold increased risk 3. Hyperhomocysteinemia correlates with an increased risk of colorectal cancer with elevated homocysteine levels being highly prevalent in patients with inflammatory bowel diseases which is believed to be associated with either an increased or decreased absorption of folate and other B vitamins 4. Hyperhomocysteinemia was associated with a 2 to 3-fold increased risk of abrupyio placentae, pregnancy-induced hypertension, and intrauterine growth restriction 5.

Copper (CU) is an essential trace mineral, naturally available in some foods and as dietary supplements. CU is a cofactor for several enzymes, known as cuproenzymes, which are involved in connective tissue synthesis, energy production, iron metabolism, neuropeptide activation and neurotransmitter synthesis. CU is also involved in brain development, immune system functioning, neurohormone homeostasis, pigmentation, regulation of gene expression, and several physiological processes, such as angiogenesis 1.
CU has been recognised as both an antioxidant and pro-oxidant. Naturally occurring within the body, free radicals interact with genetic material, damage cell walls and contribute to the development of several health problems. As an antioxidant, CU scavenges to neutralise the free radicals, aiding in the prevention of oxidative damage. Conversely, as a pro-oxidant, CU can promote free radical damage, inducing the development of health problems such as Alzheimer’s disease. Consequently, CU is vital as part of a balanced diet 2.
CU deficiency in Western countries is rare, however, altered CU metabolism may influence CU deficiency which negatively impacts the connective tissue, nervous, immune and cardiovascular systems. Such conditions that can predispose CU deficiency include: prematurity, gastric bypass, burns, over-the-counter vitamins containing zinc and iron and infants fed with unmodified cow milk 3.
Menkes disease is a rare x-linked recessive disorder of CU metabolism caused by mutations to the ATP7A gene. Menkes disease affects an estimated 1 in every 100,000 – 250,000 births and is characterised by sparse, kinky hair and failure to thrive and progressive deterioration of the nervous system. Symptoms commonly present during infancy, but, in some cases, the symptoms may present in early to middle childhood. If treatment is started early, the prognosis may improve 4.
Copper toxicity is also rare but can be caused by consuming too many dietary supplements high in copper, drinking contaminated water and from fungicides containing CU sulphates 3.
Wilson’s disease is an autosomal recessive disorder caused by mutations to the ATP7B gene, which is highly expressed in the liver, kidneys and placenta. Wilson’s disease affects approximately 1 in every 40,000 and is characterised by hepatic, neuropsychiatric and ophthalmic symptoms as a result of excess copper accumulation. Unlike most genetic diseases, early detection and implementation of a treatment plan for those with Wilson’s disease can prevent longer term morbidity due to copper induced end organ dysfunction 3.

What is Total Cholesterol assay used for?
Cholesterol measurements are used in the diagnosis and treatments of lipid lipoprotein metabolism disorders. Lipids play an important role in the body; they serve as hormones or hormone precursors, aid in digestion, provide energy, storage and metabolic fuels, act as functional and structural components in biomembranes and form insulation to allow nerve conduction and prevent heat loss.
In clinical chemistry, over the last decade however, lipids have become associated with lipoprotein metabolism and atherosclerosis.
A patient will be offered a blood cholesterol level test if they:
-
- have been diagnosed with coronary heart disease, stroke or mini-stroke
- are over 40
- have a family history of early cardiovascular disease
- have a close family member who has an inherited cholesterol-related condition
- are overweight or obese
- have high blood pressure or diabetes
- Have another medical condition such as a kidney condition, an underactive thyroid gland or pancreatitis

What is LDL Cholesterol assay used for?
Low Density Lipoproteins (LDL) are synthesised in the liver by the action of various Lipolytic enzymes on triglyceride rich Very Low Density Lipoproteins (VLDLs). Specific LDL receptors exist to facilitate the elimination of LDL from plasma by liver parenchymal cells. It has been shown that most of the cholesterol stored in atherosclerotic plaques originates from LDL. For this reason the LDL-Cholesterol concentration is considered to be the most important clinical predictor, of all single parameters, with respect to coronary atherosclerosis.
Accurate measurement of LDL-Cholesterol is of vital importance in therapies which focus on lipid reduction to prevent atherosclerosis or reduce its progress and to avoid plaque rupture.
It is recommended a patient get tested when aged 40; as part of a routine CV health check; if they are already thought to be at risk of CVD for another reason; or to monitor their response to treatments which lower LDL Cholesterol.
