Order Selenium Blood Test | Deficiency TestingSelenium is a trace element the body incorporates into selenoproteins, a family of enzymes central to antioxidant defense and thyroid hormone metabolism. Because selenium is obtained almost entirely through diet, its status reflects both intake and, in occupational settings, exposure. The Selenium Blood Test measures the concentration of selenium in the bloodstream to help evaluate whether levels are deficient or elevated.
About Selenium Blood Test | Deficiency Testing in St. Augustine
The Selenium Blood Test quantifies selenium in a blood sample, offering a direct view of body stores for this essential trace mineral.
Selenium functions as a cofactor for glutathione peroxidase and other selenoproteins that neutralize peroxides and support immune and thyroid function. Dietary sources include Brazil nuts, seafood, organ meats, and grains, though soil content influences how much selenium a given food supplies.
Measurement of blood selenium is used in two broad contexts: identifying deficiency when intake is inadequate or absorption is impaired, and monitoring overexposure in industrial or environmental settings. Symptoms of deficiency can include fatigue, muscle weakness, and hair or nail changes, while chronic excess may produce garlic-like breath, gastrointestinal upset, and neurological effects.
Results are interpreted alongside clinical history and other laboratory findings, since blood selenium concentrations can shift with recent intake, inflammation, and certain medications. The test requires a blood draw, and the reported turnaround is typically one to three business days.
