A selenium blood test measures the amount of selenium in your blood. Selenium is a mineral that supports thyroid function, immune health, and antioxidant defenses. The test is ordered when a deficiency or excess is suspected, or to monitor supplementation.

What it measures

  • Selenium (total) — The main mineral level in your blood, reported in micrograms per liter (mcg/L).
  • Selenium (plasma or serum) — The liquid part of blood, often used for routine testing.
  • Selenium (whole blood) — Measures selenium inside red blood cells, reflecting longer-term levels.
  • Glutathione peroxidase (optional) — An enzyme that depends on selenium; sometimes checked with selenium.

Who it is for

A clinician may order this test if you have symptoms of deficiency (such as fatigue or muscle weakness) or excess (such as hair loss or nail changes), or if you are on long-term selenium supplements or intravenous nutrition.

Preparation

No fasting is usually required. Tell your clinician about all supplements, especially selenium, and any medications you take.

Results and what they mean

Results are reported as a number with a reference range, typically in mcg/L. Your clinician interprets the result along with your symptoms, diet, and other tests. This is general information, not medical advice; only a qualified professional can diagnose or treat a condition.
