T3

Assessing to diagnosis & to monitor thyroid diseases(T3)

Free T4 test measures the level of the hormone thyroxine (T4) in your blood. The thyroid gland produces T4 in response to thyroid-stimulating hormone (TSH). T4 is found in the body in two forms: free T4 and bound T4. A total T4 test can measure the total amount of both free and bound T4 in the blood, while a free T4 test will only measure the amount of T4 in its free form, so it more accurately reflects how the thyroid gland is functioning.
