SELENIUM

The selenium test measures the level of selenium, an essential trace element, in the blood. Selenium is involved in various physiological processes, including antioxidant defense, thyroid function, and immune response. This test is used to diagnose and monitor conditions affecting selenium levels, such as selenium deficiency or toxicity. Low selenium levels can indicate malnutrition, gastrointestinal disorders, or increased requirements, while elevated levels suggest excessive supplementation or exposure. The selenium test provides valuable information for assessing nutritional status, diagnosing underlying conditions, and guiding treatment decisions to manage selenium levels effectively.
