About Selenium Blood Test | Deficiency Testing in Reston
Selenium is an essential micronutrient, meaning the body requires it but cannot produce it.
Selenium is incorporated into proteins known as selenoproteins, which help neutralize oxidative stress and contribute to normal thyroid hormone metabolism. Because the body does not synthesize selenium, circulating levels depend on dietary intake and, in some cases, environmental or industrial exposure.
A selenium blood test quantifies the amount of the element present in the blood. It is typically ordered when a deficiency is suspected or when someone may have been exposed to selenium through work or other sources. Symptoms that can prompt testing include unexplained fatigue, muscle weakness, or hair and nail changes.
Results are interpreted alongside clinical history and other laboratory findings. Both low and elevated selenium levels can be clinically meaningful, so the test is often used as part of a broader evaluation rather than as a stand-alone diagnostic tool.
