Thyroid hormone tests basically came in several types. The blood tests that are used in determining the amount of hormone that is produced by your thyroid glands are including the total thyroxine test, the free thyroxine test, and the triiodothyronine test. Thyroxine is also known as T4. Thyroxine can be found in the blood, attached to protein that is known as thyroxine-binding globulin. Free thyroxine is also known as FT4 or FTI. FT4 is the type of free thyroxine that can be measured directly while FTI is the type of free thyroxine which is calculated as free thyroxine index. The triiodothyronine is also known as T3. Like T4, the T3 is found in blood, attached to the thyroxine-binding globulin.

The thyroid blood test is performed for several purposes. The first reason why this type of test is done is to find out the causes of abnormal TSH or thyroid-stimulating hormone. This is considered as the main reason why the thyroid blood test needs to be performed. Other purpose of the thyroid blood test is to examine how well the treatment that is used for the patients with thyroid disease works. The values of T4, FT4, and FTI can be used to track the development of treatment that is used in treating hyperthyroidism. The last reason of why the thyroid blood test needs to be done is to find out whether the thyroid gland works normally or not in newborns. With this test, the hypothyroidism in newborns can be treated sooner.
