Order Selenium Urine Test | Deficiency TestingSelenium is a trace element that supports antioxidant defense and thyroid hormone metabolism. The Selenium Urine Test measures the amount of selenium excreted in urine, offering a direct view of recent exposure and body burden. This test is typically used in two settings: monitoring occupational exposure in industries where selenium is handled, and evaluating whether a deficiency exists when dietary intake or absorption is in question. Because selenium has a narrow margin between essential and harmful levels, urine testing provides a practical way to assess status without relying solely on blood concentrations.
About Selenium Urine Test | Deficiency Testing in Phoenix
The Selenium Urine Test helps clarify how much selenium is leaving the body through the kidneys.
Selenium is incorporated into selenoproteins, which act as antioxidants and support immune and thyroid function. The kidneys are a primary route of selenium elimination, so urine levels reflect recent intake and exposure. A urine test is often chosen for biological monitoring because it captures selenium that has been absorbed and is being cleared, making it useful for both deficiency assessment and industrial surveillance.
In occupational settings, urine selenium is used to track exposure over time. Workers who handle selenium or its compounds may accumulate higher body burdens, and periodic urine testing can show whether exposure controls are effective. In clinical contexts, low urine selenium may indicate inadequate dietary intake, malabsorption, or increased losses, though results are interpreted alongside symptoms, diet history, and other laboratory findings.
Urine selenium results are reported as a concentration or total amount per collection period, depending on the lab. Because selenium requirements and toxicity thresholds vary, reference ranges are method-specific. A single result is rarely diagnostic on its own; trends over time or comparisons with blood selenium can provide a more complete picture. Specimen collection should follow the lab's instructions to avoid contamination from diet, supplements, or environmental sources.
