How the FT4 thyroid Test Is Done :

When your doctor recommends a FT4 thyroid test, you'll likely undergo a simple blood draw specifically targeting the measurement of FT4 thyroid. A pathologist, a specialist in studying diseases, will collect a small blood sample from your veins using a needle. Your FT4 thyroid test results will typically be available within a few hours after this procedure.
