The triple test is commonly referred to as the thyroid function test, also known as the triple test of thyroid physiology, which mainly includes thyroid stimulating hormone, free thyroxine and free triiodothyronine. These hormone tests are performed in the form of a blood draw, which must be done on an empty stomach to ensure the accuracy of the test results. If the hormones show an increasing trend after the test, the patient is likely to have hyperthyroidism, while if the hormones show a decreasing trend, the disease is clinically known as hypothyroidism. The abnormal thyroid function is mainly treated by hormonal drugs, but for more serious patients, thyroidectomy may be required to achieve recovery, and later you need to pay attention to the usual dietary care.
