###Human: Does low hCG level indicate ectopic pregnancy or miscarriage? ###Assistant: Hello. Let me give you a few basic facts about beta hCG (human chorionic gonadotropin). This hormone is produced from fetal tissue. Once it reaches a level of 25 mIU/mL, it is detectable in the urine test. A normal rate of rising of beta hCG is double in 48 hours. This doubling would mean a healthy pregnancy inside uterus. Rise less than double would mean either an abnormal or ectopic pregnancy. But your level has risen satisfactorily. Many times even a rise just below double also is normal. Only when the level reaches 1500 mIU/mL, then the fetus will be seen on the scan. So do not decide about the health of the baby until the scan sees the sac or fetal heartbeat. The blood test is not always right. Just wait for 10 to 14 days and have a scan. Hope for the best and pray well. I hope I have clarified your query, do write back if any more questions, for feedback.
