Order Selenium Blood Test | Deficiency TestingThe selenium blood test measures the amount of selenium circulating in the bloodstream. Selenium is a trace element that the body incorporates into selenoproteins, which function as antioxidants and support thyroid hormone metabolism and immune response. Because the margin between sufficient and excessive intake is relatively narrow, this test is used both to identify deficiency and to monitor exposure in settings where selenium is handled industrially.
About Selenium Blood Test | Deficiency Testing in Walnut
Selenium status reflects diet, absorption, and environmental exposure rather than a single organ system.
Selenium enters the body mainly through food, with Brazil nuts, seafood, organ meats, and grains among the richer sources. The amount present in plant foods depends on the selenium content of the soil in which they are grown, so intake can vary widely even among similar diets. Once absorbed, selenium is bound to proteins and distributed to tissues, and a blood measurement captures the circulating fraction at the time of collection.
A deficiency can develop when intake is persistently low, when absorption is impaired by gastrointestinal disease, or when selenium is lost through prolonged intravenous nutrition that lacks adequate supplementation. Low concentrations have been associated with reversible impairments in antioxidant defense and, in severe cases, with cardiac and skeletal muscle effects. Interpretation is not made from the selenium value alone; clinicians consider dietary history, other nutritional markers, and the clinical picture together.
Higher-than-expected results usually point to excessive intake from supplements or to occupational exposure to selenium dusts and fumes. Chronic overexposure can produce symptoms such as garlic-like breath odor, hair loss, brittle nails, and neurological complaints. Because both deficiency and excess are possible, the test is ordered to establish where a person falls within the reference interval rather than to confirm a single suspected condition.
