The main function of the thyroid gland is to synthesize and release thyroid hormones, including thyroxine (T4) and triiodothyronine (T3)， Free Thyroxine (FT4),Fre Triiodothyronine (FT3)  and Thyroid Stimulating Hormone which play a key role in the body’s metabolism and energy utilization.

Thyroid hormones affect a person’s physical development, growth, metabolism, and overall health by regulating physiological processes such as intracellular metabolic reaction rates, body temperature, heart rate, digestive capacity, nervous system and muscle function, red blood cell production, and bone metabolism.

An overactive or underactive thyroid can cause the body’s response to these hormones to be out of balance. Hyperthyroidism can lead to accelerated metabolism, increased pulse rate, increased body temperature, and accelerated fuel consumption, while hypothyroidism can lead to slower metabolism, decreased pulse rate, decreased body temperature, and decreased body heat production.

Here We have TT3 Test,TT4 Test, FT4 Test,FT3 Test ,TSH test kit for detecting the function of Thyroid
