What Is a Thyroid Test?
Your thyroid gland is a small butterfly-shaped gland that is located just below your Adams apple or larynx in your throat. This gland has two lobes that lie near the windpipe or trachea. They are joined together by a narrow band of thyroid tissue, known as the isthmus. If the thyroid gland is not functioning properly you could develop health problems. The thyroid can be underactive or overactive. There are certain tests your doctor can perform to make sure your thyroid is functioning normally.
