Special Info

Diet, medication, and nutritional supplements may introduce interfering substances. Patient should be encouraged to discontinue nutritional supplements, vitamins, minerals, and non-essential over the counter medications (upon the advice of their physician). Specimens collected in tubes other than royal blue (EDTA), or specimens transported in containers other than a royal blue (EDTA) tube or trace element-free transport tube are unacceptable. Heparin anticoagulant is not acceptable. Clotted specimens will be rejected. This test is New York DOH approved.

Clinical Info

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.
