Selenium, Serum or Plasma

Selenium is an essential trace element that performs critical functions within the body. This blood test measures the levels of selenium in your serum or plasma, helping to assess your status of this powerful nutrient. Selenium is fundamental because it forms selenoproteins, which are key players in antioxidant activity and protecting cells from oxidative damage. Furthermore, it contributes significantly to both thyroid hormone synthesis and a robust immune response. Understanding your selenium status can be an important step toward optimizing your body's defense mechanisms and overall metabolic health.
