Order Selenium Urine Test | Deficiency TestingThe selenium urine test measures the amount of selenium excreted in urine, providing a direct view of recent selenium intake and bodily handling of this trace element. Because selenium is both an essential nutrient and a potential toxin at elevated levels, the test serves two distinct purposes: identifying a deficiency when intake is too low, and monitoring exposure when intake or occupational contact is excessive.
About Selenium Urine Test | Deficiency Testing in Pacifica
Selenium is a trace mineral that the body incorporates into selenoproteins, a family of enzymes central to antioxidant defense and thyroid hormone metabolism.
Selenoproteins help neutralize reactive oxygen species that would otherwise damage cells and DNA. The body cannot synthesize selenium, so it must be obtained from dietary sources such as Brazil nuts, seafood, meat, poultry, eggs, and grains grown in selenium-rich soil.
When selenium intake falls below physiological needs, selenoprotein activity declines. This can impair antioxidant capacity and thyroid function, and has been associated with a range of health concerns. A urine test helps clinicians assess whether body stores are adequate or depleted.
At the other end of the spectrum, excessive selenium from supplements or industrial exposure can produce toxicity, with symptoms that include gastrointestinal upset, hair loss, nail brittleness, and neurological effects. Urinary selenium reflects recent absorption and excretion, making it useful for tracking both deficiency and overexposure over time.
