Order Selenium Urine Test | Deficiency TestingSelenium is a trace element the body uses to build antioxidant enzymes and to support thyroid and immune function. A urine selenium test measures how much of this element is excreted in urine, offering a window into recent intake and bodily handling of selenium. Because both too little and too much selenium can affect health, this test is used in two distinct settings: monitoring people with industrial exposure and evaluating possible deficiency.
About Selenium Urine Test | Deficiency Testing in Hayward
What the selenium urine test measures
The test quantifies selenium concentration in a urine sample. Most selenium in the body is bound to proteins, but a fraction is excreted through the kidneys, so urine levels reflect the amount circulating and being cleared. Results are typically reported as micrograms of selenium per liter or per gram of creatinine, a normalization that accounts for how dilute the sample is.
In occupational settings, urine selenium is a recognized biomarker for workers who handle selenium or selenium-containing compounds. Serial measurements can show whether workplace controls are keeping exposure within acceptable limits. In clinical nutrition, low urine selenium may accompany inadequate dietary intake, malabsorption, or conditions that increase selenium loss, and it is often interpreted alongside blood selenium or other nutritional markers.
Selenium is found in Brazil nuts, seafood, organ meats, eggs, and grains, and intake varies widely by diet and geography. Because the margin between adequate and excessive selenium is relatively narrow, results are best read by a clinician who knows the individual's history, diet, supplements, and work environment. Follow the lab's instructions for sample collection and handling to avoid contamination or degradation that could skew the measurement.
