Order Selenium Urine Test | Deficiency TestingSelenium is a trace element the body uses to build antioxidant enzymes and to support normal thyroid and immune function. Because both too little and too much selenium can cause problems, measuring how much the body is excreting can help clarify a person's exposure status. The selenium urine test evaluates the amount of selenium present in a urine sample, offering a direct view of recent selenium handling by the body.
About Selenium Urine Test | Deficiency Testing in Vineyard
The selenium urine test measures selenium concentration in urine to assess exposure or deficiency.
Selenium occurs naturally in foods such as Brazil nuts, seafood, meats, and grains, and it is also used in some industrial processes. The body absorbs selenium from the diet and incorporates it into proteins, while excess amounts are gradually eliminated, largely through the urine. A urine measurement therefore reflects the balance between intake, storage, and excretion at the time of collection.
This test is commonly ordered when a person may have occupational exposure to selenium, such as in certain manufacturing or processing settings, or when a deficiency is suspected. Symptoms that can prompt testing include hair loss, brittle nails, fatigue, or unexplained muscle discomfort, though these signs are not specific to selenium alone. Because selenium works closely with other nutrients, results are usually interpreted alongside a person's overall clinical picture rather than in isolation.
Urine selenium results are reported as a concentration, and the laboratory provides a reference range that reflects typical values. Values below the range may suggest inadequate selenium intake or increased loss, while values above the range may indicate excessive exposure. Timing of collection, recent diet, and hydration can influence the measurement, so following the lab's collection instructions helps ensure a meaningful result. Any abnormal finding should be discussed with a qualified healthcare professional who can determine whether additional testing or follow-up is appropriate.
