Selenium (Serum)
Serum selenium is a trace-element marker measured in the NHANES 2015-2016 serum trace-elements file. Across US males aged 30 to 39, the median serum selenium is 132.5 µg/L.

Serum selenium is the serum-specimen selenium measure published with zinc and copper in NHANES 2015-2016. It is distinct from whole-blood selenium measures in other NHANES files. LabNorms uses the serum measure from CUSEZN_I and the required WTSA2YR subsample weight.

Frequently Asked Questions
Why does this page specify serum selenium?
NHANES publishes both serum and whole-blood selenium in different files and cycles. LabNorms keeps specimen types separate and uses serum selenium from CUSEZN_I for this page.
Why does selenium use NHANES 2015-2016?
Serum selenium was not published in the NHANES 2017-2018 or 2017-March 2020 public lab files. LabNorms uses the 2015-2016 serum trace-elements file.
Why are zinc, copper, and selenium generated together?
They are measured in the same file, use the same subsample design, and share the same adult slice model.
