Order Selenium Blood Test | Deficiency TestingSelenium is a trace element the body uses in small amounts, yet its role is outsized. It supports antioxidant defense, thyroid hormone metabolism, and normal immune function. Because both too little and too much selenium can cause problems, measuring the amount circulating in blood helps clarify whether a person's intake or exposure is within a healthy range.
About Selenium Blood Test | Deficiency Testing in Mclean
The selenium blood test measures the concentration of selenium in the bloodstream.
Selenium is incorporated into proteins called selenoproteins, which help neutralize oxidative stress and assist in converting thyroid hormones into their active forms. The body does not produce selenium on its own, so it must come from food sources such as Brazil nuts, seafood, meat, eggs, and grains grown in selenium-rich soil.
A blood test for selenium is typically ordered when a clinician suspects a deficiency or wants to evaluate exposure to selenium in an occupational or environmental setting. Symptoms that may prompt testing include unexplained fatigue, muscle weakness, hair loss, or changes in nail health, though these can have many causes and are not specific to selenium alone.
Results are interpreted alongside a person's diet, medical history, and other laboratory findings. Levels that fall below or above the reference range do not automatically indicate illness; they are one piece of a broader clinical picture that a healthcare professional can help interpret.
