What is Lactate Dehydrogenase assay used for?
Lactate dehydrogenase (LD) catalyses the interconversion of lactic acid and pyruvic acid. The enzyme is composed of 4 peptide chains and exists in 5 isomeric forms. LD is widely distributed throughout the body, and the highest concentrations are found in the liver, heart and skeletal muscle. LD activity is significantly elevated during myocardial infarction. Maximum levels are reached 24 to 48 hours after the onset of chest pain and may remain elevated for 7 to 12 days post infarction. Increases in LD activity are also associated with other pathological conditions including liver disease, progressive muscular dystrophy, megaloblastic and pernicious anaemia.

What is Lactate assay used for?
Increased concentration of lactate in the blood is an indicator of anaerobic metabolism i.e. blood flow to the tissues decrease and oxygen delivery is insufficient. In cases of severe oxygen deprivation “Lactic Acidosis” may occur. L-Lactate may therefore be used as an indicator of severity of circulatory failure.

What is Iron assay used for?
Iron deficiency is one of the most prevalent human disorders. In adults iron deficiency is often symptomatic of chronic blood loss. Iron deficiency results in deficient haem synthesis with the subsequent symptoms of anaemia due to tissue hypoxia. Iron (non-heme) measurements are used in the diagnosis and treatment of diseases such as iron deficiency anaemia, hemochromatosis (a disease associated with widespread deposit in the tissues of two iron-containing pigments, hemosiderin and hemofuscin, and characterized by pigmentation of the skin), and chronic renal disease.

What is GLDH assay used for?
GLDH measurements can be taken to evaluate the liver function. Elevated blood serum levels indicate liver damage. GLDH also plays an important role in the differential diagnosis of liver disease, especially in combination with aminotransferases.
Liver diseases such as toxic liver damage or hypoxic liver disease are characterised by high serum levels. In clinical trials, GLDH can also be used as a measurement for the safety of a drug.
The Randox GLDH is an optimised standard method according to the recommendations of the Deutsche Gesellschaft für Klinische Chemie. This procedure measures the non specific creep reaction.

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.
