PROVIDER INITIATED TEST - The Zinc, Packed RBC test measures the level of zinc within red blood cells, providing insight into intracellular and longer-term zinc status. Because most zinc is stored inside cells rather than in the bloodstream, this test may better reflect tissue zinc levels than a standard serum zinc test.
This test is commonly used to evaluate suspected zinc deficiency, especially when serum zinc levels are normal but symptoms such as impaired immune function, poor wound healing, hair loss, or skin changes are present. Results are often interpreted alongside other trace mineral tests for a comprehensive nutritional assessment.
