Ordering RecommendationRecommendations when to order or not order the test. May include related or preferred tests.
Limited utility as an indicator of deficiency; concentration does not correlate well with intake. Zinc, Serum or Plasma concentrations (0020097) are best for assessment of deficiency over short periods of time. For acute toxicity, Zinc, Urine (0020462) may be a more reliable indicator of exposure.

Interpretive DataBackground information for test. May include disease information, patient result explanation, recommendations, details of testing, associated diseases, explanation of possible patient results.
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.
Zinc concentration in blood has not been shown to change significantly in deficiency or with supplementation.
