Zinc
Serum zinc is a circulating trace-element measure from a NHANES one-third subsample. Across US males aged 30 to 39, the median serum zinc in NHANES 2015-2016 is 85.3 µg/dL.

Serum zinc is the circulating zinc measure published in the NHANES copper, selenium, and zinc file. Values shown here come from the 2015-2016 serum trace-elements one-third subsample and use the published WTSA2YR subsample weight. The smaller subsample gives less precise tail estimates than full-MEC analytes, so each page reports its unweighted slice n.

Frequently Asked Questions
Why does zinc use a separate trace-elements panel?
Zinc, copper, and serum selenium are measured in the same NHANES 2015-2016 serum trace-elements file and share the same one-third subsample design.
Why are the trace-element sample sizes smaller?
NHANES measured these serum trace elements in Subsample A, a one-third subsample of examined participants. LabNorms uses the required WTSA2YR subsample weight.
Are supplement users excluded?
No. LabNorms uses the full adult population distribution, excluding only age under 20, pregnancy at exam, missing analyte values, and invalid weights.
