Thyroid Panel Test is a simple blood test that uses a blood sample to evaluate the functioning of the thyroid gland. The thyroid gland is a butterfly-shaped organ, located at the base of the neck. It helps regulate the metabolism, energy generation and body temperature.
Thyroid Panel test is carried out by taking a blood sample from the patient’s vein in the arm using a needle. Then this blood sample undergoes various processes in the lab to determine the values of free total thyroxine T-4, free total triiodothyronine T-3 and thyroid stimulating hormone (TSH) in the bloodstream.
Why get tested?
