Blood tests measure the level of thyroid-stimulating hormone (TSH) in the blood, which helps determine thyroid function. High levels of the hormone indicate an under active thyroid.

Ultrasound exams detect signs of growth and other irregularities. An ultrasound scan is a diagnostic technique which uses high-frequency sound waves to create an image of internal organs.

Thyroid scans use radioactive iodine or technetium (a radioactive metallic element) to reveal any physical abnormalities of the thyroid.

Functional stimulation tests help differentiate whether the problem lies with the pituitary gland, the hypothalamus or the thyroid gland. One such test includes injecting thyrotropin-releasing hormone and measuring the pituitary’s response.
