Check Your Zinc Levels - Zinc (Zn) Test

A zinc (Zn) test is a quantitative measurement of the level of elemental zinc in blood serum or plasma. Zinc is an essential trace element that acts as a cofactor for more than 300 enzymes in the human body and plays crucial roles in immune function, wound healing, protein and DNA synthesis, and normal growth and development. Serum zinc levels are the best available indicator of overall zinc status in the body.
