Selenium, Whole Blood

This test measures the level of selenium, an essential mineral, in your blood. It helps show whether your body has the right amount needed for healthy function or if levels are dangerously high. Doctors use this result to check for nutritional deficiencies or selenium poisoning from supplements or workplace exposure. However, this test cannot identify the specific source of exposure or diagnose related organ damage on its own.
