Free T4 (FT4) and T4 Test
About Test
Components: Free T4 (FT4), Total T4
The Free T4 (FT4) and Total T4 tests are blood tests that measure the levels of the hormone thyroxine (T4) in the body. T4 is a type of thyroid hormone that plays a crucial role in regulating metabolism.
The Total T4 test measures the total amount of T4 present in the blood, including both the free and bound forms of the hormone. The Free T4 test specifically measures the amount of the hormone that is unbound and available to enter cells and perform its metabolic functions.
These tests are used to assess thyroid function and help diagnose thyroid disorders, such as hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). The results of these tests, along with other clinical and laboratory data, are used to determine the appropriate treatment for thyroid disorders.
