In clinical practice thyroid function indicators are very important items in the diagnosis of thyroid disease, and how thyroid function indicators should be looked at are roughly analyzed as follows: 1. Thyroid function indicators include thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroid hormone (FT4), triiodothyronine (TT3) and tetrodothionine (TT4). Thyroid-related antibodies include TPOAb and TGAb, which are thyroglobulin antibodies and thyroid peroxidase antibodies.2 The main indicators of thyroid function are thyroid stimulating hormone, free triiodothyronine and free thyroxine. If FT3 and FT4 are elevated while TSH is decreased it may indicate the occurrence of hyperthyroidism, while the opposite result may indicate the occurrence of hypothyroidism. Therefore, through the above analysis, the indicators of thyroid function should be analyzed according to the specific situation, and the medication is often used very safely and reliably under the guidance of a doctor.
