What Level of Serum Human Chorionic Gonadotropin Indicates Pregnancy?

Pregnancy refers to gestation. Serum human chorionic gonadotropin levels exceeding 5mIU/mL can be considered as a sign of pregnancy. The normal range of serum human chorionic gonadotropin levels is 0mIU/mL to 5mIU/mL. If the value exceeds 5mIU/mL, it may indicate that a woman is pregnant. As the gestational period continues to increase, serum human chorionic gonadotropin levels may reach 5000mIU/mL to 150000mIU/mL during the 8th to 10th weeks of pregnancy. Generally, after the 20th week of pregnancy, the level of serum human chorionic gonadotropin may decrease to around 12000mIU/mL and gradually stabilize. Serum human chorionic gonadotropin levels can be tested if menstruation is delayed for 7 days. If the value is within the normal range, it indicates that the woman is not pregnant. However, if the serum human chorionic gonadotropin level is lower than the normal range after confirming pregnancy, it is often considered as threatened abortion. In such cases, progesterone capsules, dydrogesterone tablets, and other medications can be prescribed to protect the fetus.
