Clinical Information: Zinc concentration in blood has not been shown to change significantly in deficiency or with supplementation. Elevated results may be due to skin or collection-related contamination, including the use of a noncertified metal-free collection/transport tube. If contamination concerns exist due to elevated levels of blood zinc, confirmation with a second specimen collected in a certified metal-free tube is recommended.
