The thyroid triple test during pregnancy is about$100, which mainly includes thyroid stimulating hormone, T3 and T4.The main purpose of the thyroid test is to exclude the patient from having abnormal thyroid function, such as hyperthyroidism and hypothyroidism. The thyroid gland is a very important endocrine gland in women, and it is very closely related to the growth and development of the fetus, especially the intelligence and bone development of the fetus. If the patient has hyperthyroidism, miscarriage and preterm labor will easily occur. If the patient has hypothyroidism, the growth of the fetus will be delayed, or the child will have dwarfism, mental development problems and so on. Therefore, it is very important to check the thyroid function before and during pregnancy to detect whether the patient has thyroid function abnormality in time and whether intervention is needed.
