Selenium is an essential trace mineral that plays a crucial role in various bodily functions. It acts as a powerful antioxidant, protecting cells from damage caused by free radicals. Selenium is vital for thyroid hormone metabolism, immune system function, and reproductive health. It also supports cardiovascular health and may have anti-cancer properties. This test measures the amount of selenium in the blood to assess nutritional status and detect potential deficiencies or toxicities.
