Copper and zinc are essential trace minerals, found in all bodily cells and they are necessary for survival. Although, their roles within the body differ. Copper is essential to produce red blood cells and zinc is essential for the proper function of the immune system (1) (2). Whilst both of these nutrients exist naturally in the environment including water and food, both nutrients can exist in the body in higher or lower than normal concentrations which can cause major health complications (3).

Applications are available detailing instrument-specific settings for the convenient use of the Randox Copper assay on a wide range of clinical chemistry analysers
Copper is mainly found in the brain, liver, kidneys, heart and skeletal muscle with the highest quantities found in the liver and muscles. It aids in some of the key bodily functions including: the production of red blood cells, the maintenance of nerve cells and the immune system, the formation of collagen to absorb iron for energy production, and the formation of melanin, bone and connective tissue. Ceruloplasmin is the protein responsible for the transportation of Copper around the body (4).
There are various health problems that can cause abnormal copper levels, however deficiency is less likely than toxicity because a normal diet contains plenty of copper including: organ meats, beans and wholegrains. Deficiency is more likely to occur in those who are malnourished, more likely children.
Deficiency more commonly occurs in premature babies, resulting in bone abnormalities and fractures. Menkes Disease is a rare inherited genetic disorder of copper metabolism and is characterised by sparse and kinky hair as children with this disorder are unable to absorb enough copper (5).
Toxicity can be caused by consuming too many dietary supplements high in copper, from drinking contaminated water, or from fungicides containing copper sulphates. Wilson disease is a rare inherited disorder that prohibits the liver from safely storing and excreting copper resulting in it seeping out of the liver and building up in the eyes, liver, kidneys and brain causing nerve damage, and if untreated, it can be fatal (6).

Liquid ready-to-use reagents for convenience and ease-of-use
Stable to expiry date when stored at +15 to +25°C
Applications are available detailing instrument-specific settings for the convenient use of the Randox Zinc assay on a wide range of clinical chemistry analysers
Zinc is required for various biological processes including: cell and enzyme production; the functionality of enzymes, metabolism of carbohydrates, fat and protein from dietary intake; wound healing; and the stabilisation of DNA (7) (8).
Zinc deficiency is identified as a malnutrition problem worldwide, especially in areas of high cereal intake and low animal food intake. However, other factors may contribute to low zinc levels including: the bioavailability of zinc, chronic illnesses such as diabetes, malignancy, hepatic disease and sickle cell disease. Higher zinc requirements have been identified in infants, children, adolescents, and pregnant and lactating women compared to adults. During periods of growth, zinc deficiency can result in growth failure. The most common organs affected by zinc deficiency clinically include: central nervous, gastrointestinal, epidermal, skeletal, immune, and reproductive systems (9) (10).
