Thyroid

The thyroid, a small gland located in the lower part of your neck, is vital because it controls many functions in your body. It is this gland that controls body temperature, metabolism, nervous system and the rate of heartbeat. Thyroid tests are done to check if your thyroid is functioning well and if you have issues like hypothyroidism and hyperthyroidism.

T4 - Done to measure free T4 (FT4 or FTI) and rule out hypothyroidism and hyperthyroidism
T3 - Done to confirm the diagnosis of hyperthyroidism and determine its severity
Thyroid antibody test - done to measure the level of thyroid antibodies to check if your immune system has mistakenly attacked your thyroid gland
