Hi is zinc plasma 76 mcg/dl a normal level ?

Use the reference: Zinc is typically measured using micromolar/l (mm/l) and so mcg/dl values will be a bit different. Your lab results should also contain a reference range. If my memory serves me correctly, the range is usually between 9-17 in mm/l units. By my estimate, the level seems ok. However, check you reference range. Consult doc. Good luck.

Yes: Normal levels are 66-110 mcm/dl.
