Accuracy of serum beta-human chorionic gonadotropin cutoff values at 42 and 49 days' gestation

Article Abstract:

A pregnant woman's blood level of beta human chorionic gonadotropin can be used to estimate the age of the fetus. This can be used to confirm the age of the fetus if the woman wants an abortion.

Mifepristone and misoprostol and methotrexate/misoprostol in clinical practice for abortion

Article Abstract:

The authors have evaluated the efficacy, follow-up rates and side-effect profile in women undergoing medical abortion in a nonresearch setting. Results have demonstrated that medical abortion with mifepristone and misoprostol, and methotrexate and misoprostol can be efficient in a nonresearch setting.

Change in serum beta-human chorionic gonadotropin after abortion with methotrexate and misoprostol

Article Abstract:

The concentration of human chorionic gonadotropin (hCG) in the blood may drop by at least 48% within 24 hours of having a complete abortion. Researchers analyzed blood levels of hCG in 86 pregnant women the day they received injections of misoprostol to chemically induce abortions and the day after. Eighty-three women had complete abortions, and these corresponded with decreases in blood levels of hCG of at least 48%. Two of the three women who had incomplete abortions showed little decrease of hCG in their blood. Decreases of 48% or more of hCG may confirm complete abortion in cases where ultrasound cannot confirm it. Failure of hCG to decrease after surgical abortion or miscarriage may indicate either incomplete abortion or ectopic pregnancy.
