There is no definitive means of predicting the risk of preeclampsia in the clinic, and a high risk does not mean that preeclampsia has occurred, so a high risk of preeclampsia at 15 weeks’ gestation is generally a prediction of preeclampsia. A high risk of eclampsia at 15 weeks’ gestation is generally a predictor of preeclampsia. There is no clinically proven means of predicting the risk of preeclampsia, and a high risk does not mean that preeclampsia has occurred. Pre-eclampsia is a pregnancy-specific condition that occurs after 20 weeks of gestation and is characterized by elevated blood pressure and proteinuria. Eclampsia is a convulsion that occurs on top of preeclampsia and cannot be explained by other causes, and it is a manifestation of preeclampsia that has progressed to its most severe stage. Therefore, if 15 weeks of pregnancy indicates a high risk of eclampsia, regular checkups should be performed as prescribed by the doctor.
