Zinc is a trace mineral needed for immunity, wound healing, taste, and skin function. Deficiency can cause skin problems, poor healing, and impaired immunity.
The value can be tricky to interpret - acute inflammation lowers serum zinc without the body's total stores being low.
What does low Zinc mean?
Low zinc appears with dietary or absorption deficiency, chronic inflammatory disease, and alcohol use.
What does high Zinc mean?
High zinc most often reflects supplementation.
