The zinc urine test is used to measure the amount of zinc in a person’s body. It is used to test for cases of zinc deficiency due to lack of adequate nutrition or cases of toxicity due to overexposure to the zinc element in industries or supplements. The test is also used to detect cases of zinc deficiency like Acrodermatitis enteropathica, occurring due to improper absorption of zinc. Zinc plays a very important role in wound healing and the test is also carried out in cases of delayed wound healing, growth retardation in children and in cases of diabetes in adults. The test is also carried out to check for increased zinc levels. Excessive zinc levels may suppress the absorption of other elements like copper leading to hypocupremia.
