In early pregnancy, T3 refers to triiodothyronine, with normal values between 0.6-1.61ng/mL, and T4 refers to tetraiodothyronine, with normal values between 4.5-10.9ug/dL.
Thyroid T3 and T4 are hormones secreted by the thyroid gland, which can determine whether the thyroid function is normal or not. T3 refers to triiodothyronine and T4 refers to tetraiodothyronine, which are formed by the combination of iodine and proteins, and the difference lies in the difference of iodine ion concentration, which are interconnected with each other, and the elevation and the decrease can be kept in sync.
The normal value of T3 in early pregnancy is between 0.6-1.61ng/mL, and the normal value of T4 is between 4.5-10.9ug/dL. The elevation of T3 and T4 indicates that the thyroid gland may be hyperfunctional, and the decrease of T3 and T4 concentration indicates that the thyroid gland is hypothyroid.
Thyroid hormone is more important in pregnancy, is the fetus, the newborn brain formation and development of important substances, pregnancy detection of abnormalities timely treatment to reduce the impact on fetal development.
