If there is a suspicion of thyroid abnormality or endocrine disease, it is necessary to check the thyroid test. For other diseases, it is not necessarily necessary to check the thyroid function test, and it is recommended to follow the doctor’s instructions to carry out the relevant tests. Thyroglobulin 5 includes thyroid stimulating hormone (TSH), triiodothyronine (T3), free triiodothyronine (FT3), free thyroxine (FT4) and thyroxine (T4). The results of the above indicators can assist the doctor in determining whether the thyroid function is abnormal or not. If there are cases of irregular menstruation, weight loss, excessive sweating, insomnia and excessive dreaming, or enlarged thyroid gland, it is necessary to check the thyroid 5 under the guidance of the doctor. If the thyroid function is abnormal, it is recommended to follow the doctor’s instructions for treatment.
