The normal range of serum thyroid stimulating hormone for pregnant women is divided into three periods. Early pregnancy is between 0.1 and 2.5 uIU/ml, mid-pregnancy is between 0.2 and 3.0 uIU/ml, and late pregnancy should be between 0.3 and 3.0 uIU/ml. Due to different examination methods and reagents, the reference indexes of each hospital are different and need to be analyzed specifically.
After pregnancy, it is necessary to check the thyroid function, because abnormal thyroid function may lead to miscarriage, abnormal fetal development, and may also affect fetal intelligence. Because thyrotropin regulates the synthesis and secretion of thyroid hormones, which will affect the normal growth and development of the fetus, especially its brain development, the thyrotropin of pregnant women needs to be maintained within the normal range.
Pregnant women with abnormal serum thyroid stimulating hormone are advised to seek medical attention.
