Thyroid function test (TFT)

A thyroid function test (TFT) measures how well your thyroid gland is working by analyzing blood levels of hormones such as TSH, T3, and T4. The thyroid gland helps regulate important body functions like energy, metabolism, and temperature. Elevated or low levels of these hormones can indicate conditions like hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid). TFTs are essential in diagnosing thyroid disorders, guiding treatment, and monitoring responses to therapy. The test is simple: a blood sample is taken, and results provide insight into the health of your thyroid gland.
