Order Selenium Blood Test | Deficiency TestingThe selenium blood test measures the amount of selenium circulating in the bloodstream. Selenium is a trace element the body incorporates into selenoproteins, a family of enzymes central to antioxidant defense and thyroid hormone metabolism. Because the margin between adequate and excessive intake is relatively narrow, this test serves two distinct purposes: identifying a deficiency when intake or absorption falls short, and monitoring exposure in settings where industrial contact with selenium may occur.
About Selenium Blood Test | Deficiency Testing in Pasadena
Selenium is a trace mineral the body needs in small but steady amounts.
Selenium is incorporated into selenoproteins such as glutathione peroxidase, which help neutralize peroxides and other reactive molecules produced during normal metabolism. It also supports the conversion of thyroid hormones and contributes to immune function. Dietary selenium comes chiefly from grains, nuts, seafood, eggs, and organ meats, and the amount present in plant foods depends on the selenium content of the soil where they were grown.
A deficiency can develop when dietary intake is persistently low, when the mineral is poorly absorbed because of gastrointestinal disease, or in individuals receiving long-term intravenous nutrition without adequate supplementation. Low selenium status has been associated with fatigue, muscle weakness, and impaired immune response, though these findings are nonspecific and require laboratory confirmation before they can be attributed to selenium.
Excess selenium is also a concern. Very high intakes, whether from supplements or occupational exposure to selenium dusts and fumes, can produce selenosis, marked by hair loss, brittle nails, gastrointestinal upset, and a garlic-like odor on the breath. The blood test is therefore used both to detect insufficiency and to monitor individuals whose work or treatment places them at risk of overexposure. Results are interpreted alongside dietary history, symptoms, and other laboratory findings.
