Abstract Objective: To explore the effect of dynamic monitoring serumβ-hCG level of women after medical abortion for predicting abortion outcomes. Methods: The data of pregnant women within 49 gestational days who had experienced medical abortion were analyzed retrospectively. The serum β-hCG level of all included women were detected before abortion, and on the 10th and 20th day after abortion. And the change ofβ-hCG level were observed. Results: The serum β-hCG level of women with incompleted abortion before abortion, and on the 10th and 20th day after abortion were all significant higher than those of women with completed abortion (P<0.001). The descending rate of serum β-hCG level of women with completed abortion on the 10th day and 20th were 94.0±12.0% and 99.6±12.6%, which were all significant higher than those(61.1±8.6% and 94.1±12.1%) of women with uncompleted abortion（P=0.001, 0.005）. ROC working curve analysis showed that when the decrease rate of serumβ-hCG level was over 93.49% on the 10th day after abortion, and that was over 97.87% on the 20th day after abortion, the abortion prognosis could be better. Conclusion: The decrease rate of serumβ-hCG level of women should be dynamically monitored after medical abortion, which is expected to provide a reference for further surgical intervention.
