Order Selenium Urine Test | Deficiency TestingSelenium is a trace element the body incorporates into selenoproteins, a family of enzymes that help defend cells against oxidative damage and support thyroid hormone metabolism. Because both too little and too much selenium can affect health, measuring how much of it leaves the body in urine offers a practical view of recent selenium status. This test quantifies selenium in a urine specimen, giving a direct picture of what the body is excreting rather than what is circulating in blood.
About Selenium Urine Test | Deficiency Testing in Cupertino
Selenium in urine reflects the balance between dietary intake, tissue use, and renal clearance.
Most selenium in the body is bound within selenoproteins, where it acts as a cofactor for antioxidant enzymes such as glutathione peroxidase. When intake exceeds the body's needs, the surplus is largely excreted in urine, so urinary selenium tends to track recent exposure and absorption. A low urinary value can suggest inadequate intake or impaired absorption, while a high value may point to excessive supplementation or occupational exposure.
Urine collection is a common approach in both clinical and occupational settings because it captures selenium that has moved through the bloodstream and been cleared by the kidneys. Results are usually interpreted alongside dietary history, supplement use, and any workplace exposure to selenium-containing dusts or compounds. Because excretion varies with hydration and recent intake, the specimen is typically collected under the conditions the laboratory specifies.
Selenium deficiency is uncommon in many populations, but it can occur with prolonged poor intake, certain malabsorption conditions, or dependence on soils low in selenium. Conversely, chronic overexposure can cause selenosis, with symptoms such as hair loss, brittle nails, and gastrointestinal upset. A urine selenium measurement helps distinguish inadequate status from excessive accumulation and supports decisions about diet or exposure controls.
