What is this test?

This test measures the amounts of zinc and creatinine in a laboratory sample. Zinc is an essential mineral, while creatinine is a waste product commonly used to assess kidney function.

Why might I need this test?

A clinician may order this test to investigate unusual zinc levels, nutritional problems, medication effects, or possible exposure to zinc. If the specimen is urine, creatinine may also be used to account for variations in urine concentration.

How is the test performed?

A laboratory analyzes the specimen using a turbidimetric method, which estimates the amount of a substance by measuring how much it clouds a solution. The specimen type is not specified by the abbreviated code and should be confirmed with the ordering laboratory.

How do I prepare for the test?

Follow the laboratory's instructions for the specific specimen, including any timed or first-morning collection. Tell your clinician about zinc supplements or other relevant medicines, but do not stop prescribed supplements unless instructed.
