Hypothyroidism report requires attention to total T3, total T4, free T3, free T4, thyroid stimulating hormone levels, and thyroid related antibody results. Hypothyroidism is a disease in which the body’s metabolism slows down due to insufficient production of thyroid hormones. If the levels of total T3, total T4, free T3, and free T4 are decreased, and the level of thyrotropin is increased, primary hypothyroidism is considered; if the levels of total T3, total T4, free T3, free T4, and thyrotropin are decreased, central hypothyroidism is considered. If only the thyroid stimulating hormone level is elevated, free T3 and free T4 are normal, subclinical hypothyroidism is considered; if the thyroid-related antibody is very high, hypothyroidism caused by autoimmune factors needs to be considered. It is recommended that patients with suspected hypothyroidism go to regular hospitals for timely consultation, complete relevant examinations and standardize treatment under the guidance of doctors to avoid delays.
