Order Selenium Blood Test | Deficiency TestingThe Selenium Blood Test measures the concentration of selenium in the bloodstream. Because selenium is a trace element that the body cannot produce on its own, this test is used to gauge whether intake is adequate or whether exposure to the element has become excessive.
About Selenium Blood Test | Deficiency Testing in Pharr
Selenium supports several core physiological functions, and its status is often assessed when symptoms or circumstances suggest an imbalance.
Selenium is incorporated into selenoproteins, a family of enzymes that help defend cells against oxidative damage and assist in thyroid hormone metabolism. The amount present in blood reflects recent dietary intake and absorption, which is why the test is typically used to investigate deficiency rather than to diagnose a specific disease.
Low selenium status can occur when dietary intake is persistently inadequate or when absorption is impaired by certain gastrointestinal conditions. Prolonged deficiency may be associated with subtle changes in immune function and other physiological effects, though clinical signs are often nonspecific and require interpretation alongside a person's history and other laboratory results.
The test is also used in occupational settings to monitor people who work with selenium or selenium-containing compounds, since overexposure can produce toxicity. Because both deficiency and excess carry health implications, results are generally evaluated against established reference ranges and considered in the context of symptoms, diet, and potential exposure.
