Thyroid hormone is only a little bit high in the 7-item thyroid test, which is mostly abnormal, and may be subclinical hypothyroidism; it may also be a testing error, and the reference value range may be slightly different in different hospitals, so it can be reviewed if necessary. Patients with subclinical hypothyroidism may have a mild increase in serum thyroid stimulating hormone levels, but the serum thyroid hormones, including TT4, TT3, FT4, FT3, etc., are within the normal range, as well as thyroid autoantibody indexes are normal, and the patient may not have obvious clinical manifestations or only have mild hypothyroidism symptoms. Patients with subclinical hypothyroidism are recommended to have regular checkups. Some subclinical hypothyroidism may develop into clinical hypothyroidism, which needs to be treated as early as possible. However, only a little bit of high thyrotropin may be a testing error, which is normal, and the reference value range may be slightly different in different hospitals, and can be reviewed if necessary. It is recommended to go to the hospital if only a small amount of thyrotropin is detected in the 7-item thyroid test.
