May 25 is World Thyroid Day. Thyroid disorders affect an estimated 20 million people in the United States – that’s more than 12% of the U.S. population. Thyroid disorders like hyperthyroidism, hypothyroidism, Graves disease, and even thyroid cancer are caused by abnormal activity in the thyroid that can be detected using laboratory testing. PathGroup offers tests that assist healthcare providers in diagnosing thyroid disorders in their patients. To learn more about these testing options, visit the online Directory of Services.
