Order Selenium Blood Test | Deficiency TestingThe Selenium Blood Test measures the concentration of selenium in the bloodstream.

This assay is used both to assess nutritional status and to monitor exposure in occupational settings where selenium is handled.
About Selenium Blood Test | Deficiency Testing in Altadena
Selenium is an essential micronutrient, meaning the body requires it but cannot synthesize it.
Dietary selenium comes from sources such as Brazil nuts, seafood, organ meats, and grains, and the amount absorbed depends on the chemical form and the soil content where food is grown. Once absorbed, selenium is incorporated into selenoproteins, including glutathione peroxidases and iodothyronine deiodinases, which help defend cells against oxidative damage and support thyroid function.
A selenium deficiency can develop when intake is persistently low, when absorption is impaired by gastrointestinal conditions, or when requirements increase. Low levels may be associated with weakened antioxidant defenses, while excessive intake can produce toxicity marked by hair loss, brittle nails, gastrointestinal symptoms, and neurological effects. Because the margin between adequate and excessive intake is relatively narrow, measurement of blood selenium provides useful objective information.
The test is typically ordered to evaluate suspected deficiency, to investigate symptoms consistent with selenosis, or to monitor individuals with known industrial exposure. Results are interpreted alongside dietary history, clinical findings, and other laboratory data, since blood selenium reflects recent intake and does not by itself establish a diagnosis.
