Quick answer
The Selenium Blood Test measures the amount of selenium in a blood sample. Selenium is an essential trace element obtained mainly from food, and it supports antioxidant enzymes and normal thyroid and immune function. The test is used to assess selenium status when a clinician suspects low intake, poor absorption, or excess exposure.
What this test measures
Selenium is incorporated into proteins such as glutathione peroxidase, which help protect cells from oxidative damage. Dietary sources include Brazil nuts, seafood, meat, eggs, and grains, and intake varies widely with soil content and diet. Blood selenium reflects recent status, and both low and high levels can be relevant to health.
The test uses a standard blood draw, and results are reported as a concentration, typically in micrograms per liter or micromoles per liter, with laboratory-specific reference ranges. Selenium is sometimes measured as part of a broader nutritional or trace element panel that includes zinc, copper, and other markers. Whole blood or serum may be used depending on the laboratory.
People may order this test when nutritional deficiency is suspected, when absorption problems are being evaluated, or when excessive intake from supplements or environmental exposure is a concern. It is not a routine screening test for everyone. A qualified healthcare provider interprets the result with diet, supplements, and clinical context.
