Zinc Test

A zinc test is a laboratory test that measures the level of zinc in the blood. Zinc is an essential mineral that plays a vital role in many bodily functions, including growth and development, immune function, and wound healing.

Pre-test preparation: No special preparation is typically required for a zinc test.

Testing method:  A small sample of blood is taken from a vein in the arm and sent to a laboratory for analysis. The sample is usually analyzed using a device called an atomic absorption spectrophotometer.

Common symptoms for prescribing this test:  A zinc test may be ordered if a person has symptoms of a condition that affects the level of zinc in the blood, such as malnutrition, malabsorption, or certain types of liver or kidney disease. It can also be used to monitor treatment of zinc deficiency or to detect early onset of zinc deficiency.

Diagnosis: The results of a zinc test are used to help diagnose and monitor a variety of conditions, including zinc deficiency, malnutrition, malabsorption, and certain types of liver or kidney disease. Elevated levels of zinc can indicate liver disease, while low levels can indicate zinc deficiency, malnutrition, or malabsorption.

Reference range: The reference range for zinc levels varies depending on the lab and the population being tested, but generally, a normal range is 70 to 150 mcg/dL.

Normal values: Zinc levels are normally between 70 to 150 mcg/dL.
