Population Distribution
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 shown together?
They are measured in the same file, use the same subsample design, and are broken down by the same age and sex groups.
