What is the normal level of human chorionic gonadotropin?

The normal reference range for human chorionic gonadotropin (hCG) varies depending on individual differences and the stage of pregnancy. In non-pregnant individuals, the normal hCG level is typically below 5 mIU/mL or 7 mIU/mL, generally not exceeding 10 mIU/mL. An elevated hCG level above this range, especially in women of childbearing age, may indicate pregnancy. Monitoring hCG levels is important not only for confirming pregnancy but also for diagnosing conditions such as incomplete abortion, ectopic pregnancy, and threatened miscarriage. Significantly elevated hCG levels may require further evaluation to rule out diseases such as gestational trophoblastic tumors. Abnormal hCG levels should be managed according to the specific clinical condition. For example, ectopic pregnancy may require surgical intervention; incomplete abortion may necessitate uterine evacuation; and gestational trophoblastic tumors may require comprehensive treatment including chemotherapy or surgery. Additionally, maintaining healthy lifestyle habits and undergoing regular medical check-ups can help prevent the occurrence of related diseases.
