Selenium Whole Blood Test
Item # LC081034
An important trace mineral for detoxification and thyroid health
This test measures your levels of selenium, a trace mineral and an important antioxidant that helps regulate thyroid function. Selenium also plays a role in the immune system, DNA repair and the detoxification of heavy metals.
Selenium is a trace mineral and an important antioxidant. Selenium is incorporated into proteins to make selenoproteins, which are important antioxidant enzymes. The antioxidant properties of selenoproteins help prevent cellular damage from free radicals.
Selenium has also been shown to help regulate thyroid function and to play a role in the immune system, DNA repair, and the detoxification of heavy metals. Whole blood testing for selenium is the preferred way to assess long-term status of selenium. Whole blood levels respond to changes in dietary selenium intake, as approximately 75% of blood selenium is contained in the plasma fraction, with the remainder in red cells.
Instructions
Fasting is not required for this test. Take all medications as prescribed.
