Order Selenium Urine Test | Deficiency TestingThe Selenium Urine Test measures the amount of selenium excreted in urine, providing a direct view of recent selenium status and exposure. Because selenium is both an essential nutrient and a substance with a narrow safe range, this test is used in two distinct settings: assessing whether intake is adequate, and monitoring occupational or environmental exposure.
About Selenium Urine Test | Deficiency Testing in Martinez
Selenium is a trace element the body cannot produce on its own; it must come from food or supplements.
Selenium supports antioxidant defense through enzymes such as glutathione peroxidase, and it contributes to thyroid hormone metabolism and normal immune function. Urine is one of the main routes by which the body clears selenium, so the amount present in a urine sample reflects how much has been absorbed and processed.
A deficiency can develop when dietary intake is persistently low, when absorption is impaired by gastrointestinal disease, or in certain clinical situations such as 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 not specific to selenium alone.
At the other end of the range, excessive selenium from supplements, contaminated food, or workplace exposure can cause selenosis, with symptoms that may include hair loss, brittle nails, gastrointestinal upset, and a garlic-like odor on the breath. Urine testing helps distinguish normal excretion from the elevated levels that suggest overexposure. Results are interpreted alongside dietary history, symptoms, and other clinical findings rather than in isolation.
