Useful For/Utility

May be useful as an indicator of acute deficiency.

Clinical Information

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 serum/plasma zinc, confirmation with a second specimen collected in a certified metal-free tube is recommended.

Circulating zinc concentrations are dependent on albumin status and are depressed with malnutrition.  Zinc may also be lowered with infection, inflammation, stress, oral contraceptives, and pregnancy.  Zinc may be elevated with zinc supplementation or fasting.  Elevated zinc concentrations may interfere with copper absorption.

This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes

 

Serum Zn levels are 16% higher that plasma Zn levels. Correctly assayed serum Zn levels can be converted to plasma by multiplying by 0.85.　 Plasma Zn = 0.85 Serum Zn.　Reference: Biochemistry of Zinc, Ananda S. Prasad, Plenum Press, New York and London, 1993.
