Test Description

Chromium, Serum

Chromium (Cr) has many industrial uses and is discharged in the environment as industrial waste. In the body, it exists in the +3 and +6 oxidation states. Cr functions in the control of glucose and lipid metabolism. Cr potentiates insulin action and insulin resistance may be the result of chromium deficiency. Insulin appears to be ineffective as a glucose regulator without Cr.

Deficiency symptoms may include high or low blood glucose, lean tissue wasting, anxiety, fatigue, retarded growth, decreased glycogen reserves, high blood lipids and possibly heart disease and diabetes.

Sources for Cr are brewer's yeast, liver, meat, cheese, legumes, beans, peas, whole grains, black pepper, and molasses.
