About Selenium Urine Test | Deficiency Testing in Encinitas
This test is used in two main settings: monitoring exposure in industrial or occupational environments, and evaluating whether a selenium deficiency may be present.
Selenium is incorporated into selenoproteins, including glutathione peroxidases and thioredoxin reductases, which help neutralize oxidative stress. Because the body does not synthesize selenium, its status depends on dietary sources such as Brazil nuts, seafood, meat, and grains grown in selenium-rich soil.
Urine is a practical medium for assessing selenium because the kidneys are a primary route of excretion. Results are typically interpreted alongside dietary history, symptoms, and other laboratory findings rather than as a stand-alone diagnosis.
Both low and high selenium states matter. Deficiency can impair antioxidant defense, while excessive exposure can produce toxicity, so testing is often used to confirm that levels fall within an expected range.
