what is the name of the test for your thyroid?
Thyroid function tests (TFTs) is a collective term for blood tests used to check the function of the thyroid.
It is part of the body's feedback system to maintain stable amounts of the thyroid hormones thyroxine (T4) and triiodothyronine (T3) in the blood and to help control the rate at which the body uses energy. A TSH test is frequently ordered along with or preceding a free T4 test.
