Overview

Experts do not agree on whether adults who don't have symptoms of thyroid problems should have a thyroid test. The American Thyroid Association and the American Association of Clinical Endocrinologists recommend that testing be considered for those older than age 60.^{footnote 1} The U.S. Preventive Services Task Force makes no recommendation for or against screening for people who do not have symptoms of thyroid problems. The USPSTF states that there is not enough evidence to support screening.^{footnote 2}

Talk to your doctor about whether testing is right for you.

People who have a family history of medullary thyroid cancer (MTC) may want to have a genetic test. Before having the test, it is a good idea to talk with a genetic counselor. He or she can help you understand what your test results may mean.
