What is the purpose of this test?
The Selenium Blood Test measures the amount of selenium, an essential mineral, in your blood. Selenium is important for several bodily functions, including supporting the immune system, thyroid function, and antioxidant defense. It is obtained through diet from foods like seafood, meats, nuts, and grains.
During the test, a blood sample is taken from your arm and analyzed to determine your selenium levels. This test helps healthcare providers assess your selenium status and detect deficiencies or excesses. Low selenium levels may indicate a diet lacking in selenium-rich foods or conditions affecting absorption, potentially leading to weakened immune function or thyroid problems. On the other hand, high selenium levels can also be harmful, causing symptoms like hair loss, gastrointestinal issues, or nerve damage. Understanding your selenium levels through this test allows for appropriate dietary recommendations or supplements to maintain optimal health.
