Order Selenium Blood Test | Deficiency TestingSelenium is a trace element the body uses in small amounts, yet it supports antioxidant defense and normal thyroid and immune function. A selenium blood test measures how much of this mineral is circulating in the bloodstream, giving a direct look at a nutrient level that diet and environment can both influence.
About Selenium Blood Test | Deficiency Testing in Reston
The test is typically ordered for one of two reasons: to check for a deficiency or to monitor exposure in an industrial setting.
Selenium is incorporated into proteins called selenoproteins, which help neutralize oxidative stress and assist in converting thyroid hormones into their active forms. Because the body cannot make selenium on its own, circulating levels reflect what is absorbed from food, supplements, or, in occupational settings, inhaled dust and fumes.
Deficiency is uncommon in well-nourished populations, but it can arise from prolonged poor intake, certain gastrointestinal conditions that impair absorption, or dependence on long-term intravenous nutrition. Symptoms are often subtle and nonspecific, which is why a blood measurement is more informative than guessing from how a person feels.
At the other end of the spectrum, too much selenium is toxic. Workers involved in mining, smelting, glass manufacturing, or electronics may be monitored periodically to ensure exposure stays within safe limits. Results are interpreted against the laboratory's reference range alongside dietary history, symptoms, and any known exposure.
