Selenium, Serum
Selenium, Serum is a clinical biomarker on the Nutrients panel, reported in ug/L. Standard reference range: 63–160 ug/L. Functional (optimal) range used by integrative practitioners: 70–121 ug/L.
What is Selenium, Serum?
Serum selenium reflects short-term selenium status. Selenium is incorporated into selenoproteins including glutathione peroxidase (GPx) and thyroid deiodinases; adequate status is required for antioxidant defense, T4→T3 conversion, and immune function. Serum selenium responds within days to weeks of intake change; RBC selenium is a better marker of longer-term status.
Reference ranges
| Range type | Value (ug/L) | Source |
|---|---|---|
| Standard (lab) | 63–160 | Typical Quest / LabCorp adult reference |
| Functional (optimal) | 70–121 | Integrative / functional medicine consensus |
