HCG 5800 mIU/ml indicates how many weeks of pregnancy?

　　HCG generally refers to human chorionic gonadotropin. Under normal circumstances, a human chorionic gonadotropin (hCG) level of 5800 mIU/mL usually indicates pregnancy of more than 4 weeks. Human chorionic gonadotropin is a glycoprotein hormone secreted by the trophoblastic cells of the placenta. Typically, at 4–5 weeks of gestation, hCG levels range between 1,000 and 50,000 mIU/mL. Detailed analysis is as follows:

　　Human chorionic gonadotropin is composed of α and β subunits of glycoprotein. After implantation of the fertilized egg, elevated levels of hCG can be detected in peripheral blood. Generally, when hCG levels rise to above 10 mIU/mL, pregnancy can be diagnosed. At 4–5 weeks of pregnancy, hCG values typically range from 1,000 to 50,000 mIU/mL; at 5–6 weeks, hCG levels are usually between 10,000 and 100,000 mIU/mL. During early pregnancy, hCG levels typically double every two days. Therefore, an hCG level of 5800 mIU/mL suggests that the patient has been pregnant for over 4 weeks.

　　Changes in hCG levels also have diagnostic and therapeutic significance for ectopic pregnancy. In cases of ectopic pregnancy, hCG secretion is reduced, and levels do not increase by more than 50% within 48 hours. If hCG levels are low or abnormal, this may lead to adverse outcomes such as fetal growth restriction, abnormal fetal development, or cessation of fetal development. It is recommended to seek timely medical evaluation and treatment at a hospital.

　　When pregnant women undergoing prenatal checkups find changes in their hCG levels, they should undergo ultrasound examinations to monitor fetal growth and development. If any abnormalities are detected, treatment under the guidance of a physician is advised.
