The difference between a triple and a quintuple is that there are two less tests, total triiodothyronine (TT3) and total free thyroxine (TT4), and the prices of the two are also different. Thyrotrophin (FSH), free triiodothyronine (FT3), and free thyroxine (FT4) are tested. The Pentathlon is a test for thyrotropin (FSH), free triiodothyronine (FT3), free thyroxine (FT4), total triiodothyronine (TT3), and total free thyroxine (TT4). The price of the Penta is higher than that of the Triple Thyroid Test, and the advantage of the Penta over the Triple Thyroid Test is that it helps the doctor to better evaluate the thyroid function, and it is more sensitive for people with early hyperthyroidism. When there is an abnormality in the thyroid function test, it is necessary to consult the doctor and follow the doctor’s instructions for reasonable treatment.
