Order Selenium Blood Test | Deficiency TestingThe Selenium Blood Test measures the concentration of selenium in the bloodstream, offering a direct view of this essential trace element's status in the body. Because selenium supports antioxidant defense and thyroid hormone metabolism, both insufficient and excessive levels carry health implications. This test is used clinically to identify a deficiency or to monitor exposure in occupational settings where selenium handling occurs.
About Selenium Blood Test | Deficiency Testing in Troy
Selenium is a trace mineral obtained primarily through diet, and its blood level reflects recent intake and physiological reserve.
Selenium functions as a component of selenoproteins, including glutathione peroxidases and thyroid hormone deiodinases, which help neutralize oxidative stress and regulate hormone conversion. The body does not synthesize selenium, so circulating concentrations depend on dietary sources such as Brazil nuts, seafood, eggs, and grains. Blood measurement captures the element's presence in serum or whole blood, depending on the laboratory method, and serves as a practical index of nutritional adequacy or overexposure.
A deficiency in selenium can arise from prolonged inadequate intake, malabsorption conditions, or dependence on parenteral nutrition without supplementation. Low levels may be associated with impaired antioxidant capacity and, in severe cases, with specific deficiency syndromes affecting cardiac and skeletal muscle. Conversely, excessive selenium from supplements or industrial exposure can produce toxicity marked by gastrointestinal symptoms, hair loss, and neurological effects. Testing helps distinguish between these states and guides clinical or workplace decisions.
This test is typically ordered when a clinician suspects a nutritional shortfall, when monitoring patients on long-term intravenous nutrition, or when evaluating workers with potential occupational contact with selenium compounds. Results are interpreted alongside dietary history, symptoms, and other laboratory findings. Turnaround time is generally one to three business days, and preparation follows the laboratory's instructions, which may include timing considerations relative to recent supplement intake.
