To check thyroid function, you can choose to check thyroid function triple test, thyroid function penta test, thyroid function octa test and so on. Patients are advised to follow the doctor’s advice to choose the appropriate test program. Thyroid Function Penta test mainly refers to the measurement of free triiodothyronine, free thyroxine, and triiodothyronine, thyroxine, thyrotropin, thyrotropin, and thyroid stimulating hormone, which can provide feedback on the functional status of the thyroid gland. The Thyroid 8 includes thyrotropin, free triiodothyronine, triiodothyronine, total thyroxine, free thyroxine, antithyroglobulin antibodies, antithyroid peroxidase antibodies, and antithyroid microsomal antibodies. In patients with abnormal thyroid function, thyroid-related antibodies and thyroid ultrasound should be completed at the same time as thyroid function tests.
