Thyroid profile test, also called thyroid function tests, is a series of blood tests to detect how your thyroid gland is functioning. When you experience symptoms that originate from problems in the thyroid gland, the thyroid profile test is recommended by your doctor. It involves giving your blood sample.
Thyroid is a small gland located at the front of your throat, below the Adam's apple or the larynx. It secretes hormones to control many metabolic processes such as growth and energy expenditure. It steadily releases the thyroid hormones into your bloodstream. There are different categories of tests based on your symptoms such as thyroid stimulating hormone (TSH) thyroxine (T4) and triiodothyronine (T3).
