Thyroid tests

Checking for thyroid function

A few different blood tests can be used to check your thyroid function:

TSH test

Your doctor uses this test to look for the concentration of thyroid-stimulating hormone (TSH) in your blood. Your body produces more TSH when the thyroid is less active. It also produces less T3 and T4 hormones. A below-normal level of TSH indicates hyperthyroidism, or an overactive thyroid. A high level indicates hypothyroidism.

T4 test

This test will look for the levels of T4 hormone in the blood. This hormone is either inactive and bound to proteins, or active and unbound. A high level indicates a possibility for hyperthyroidism.

T3 test

T3 is another hormone produced by the thyroid. Doctors use this test to confirm hyperthyroidism. Levels of T3 don’t decrease substantially until the condition is severe. Therefore, doctors and lab technicians will use another test to determine hypothyroidism.

TSI test

This test is used to identify the presence of an antibody called thyroid-stimulating immunoglobulin, which is present in people with Graves’ disease. Graves’ disease is an autoimmune disorder that affects thyroid function. This test is most often used on pregnant women or people who may have Graves’ disease.
