What this test is

This test quantifies selenium, a trace mineral that acts as an antioxidant and supports thyroid and immune function. It is used to monitor industrial exposure or to evaluate a possible deficiency.

What it measures

  • Selenium — Reflects recent selenium intake and body status.
  • Selenium level — Used to assess deficiency or excess exposure.
  • Whole blood selenium — Measures selenium in whole blood, which may better reflect long-term status.

What the test involves

A healthcare professional collects a small sample of blood, usually from a vein in your arm. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test if you have symptoms of deficiency, such as muscle weakness or hair loss, or if you work with selenium in an industrial setting. It can also be part of a nutritional assessment.

Preparation

Your lab will provide specific instructions, which may include fasting or avoiding certain supplements. Always follow the collection lab's guidance.

How results are reported

Results are reported as a concentration of selenium in your blood, often in micrograms per deciliter or micromoles per liter. Reference ranges vary by laboratory, so your result should be interpreted in the context of the lab's own range.

Before you go

  • Whether fasting is required before the test
  • If you should avoid certain supplements or foods
