    Test Description

    Zinc, RBC

    Zinc is second to iron as being the most abundant trace mineral present in the body. It is an important component of nearly 300 enzymes in different species. It is found in high concentrations in the prostate, semen, liver, kidney, hippocampus, retina, bone and muscle.

    Zinc is important in DNA and protein synthesis, fertility, skin growth, healing, taste buds, protein digestion, carbon dioxide removal, disease resistance, immunity, etc. Too much calcium, copper or fiber in the diet, or the use of oral contraceptives may increase the need for zinc.

    Deficiency symptoms of zinc may include stunted growth, poor wound healing, loss of taste and smell, sterility, impotence, prostate problems, lower disease resistance, acne or skin problems and may contribute to liver, kidney and heart disease.

    The RDA for zinc is 11 mg/day. It is found in oysters, herring, clams, wheat germ, bran, oatmeal, liver, nuts, beef, lamb, chicken, peas and carrots.

    Specimen required is outlined in each specific segment: urine, RBC, serum, hair.
