T3+T4+TSH Test

The T3, T4, and TSH test, also known as the thyroid function test or thyroid profile, is a blood test that measures the levels of triiodothyronine (T3), thyroxine (T4), and thyroid-stimulating hormone (TSH) in the bloodstream. These are vital thyroid hormones that play a crucial role in regulating metabolism, energy production, and various bodily functions. The T3, T4, and TSH test is commonly used to assess thyroid function and diagnose thyroid disorders. Abnormal levels of T3, T4, or TSH can indicate an overactive thyroid (hyperthyroidism) or an underactive thyroid (hypothyroidism). This test provides a comprehensive evaluation of the thyroid gland's health and function, helping healthcare professionals determine the underlying cause of thyroid dysfunction and guide appropriate treatment plans.
