Screening based on maternal factors

Pregnant women with low risk of pre-eclampsia assessment and no suspected pre-eclampsia symptoms in the later period are only followed up at delivery to register the outcome indicators. For pregnant women with high risk of preeclampsia evaluation, it is necessary to register the history of drug use (whether or not to use and the dosage), and follow up to register the outcome index at delivery.

Screening based on FMF model

Preeclampsia risk assessment should be carried out at 11-13+6 weeks and 20-36+6 weeks of pregnancy. For low-risk pregnant women (PlGF≥100pg/ml or sFlt-1 /PlGF \<38), it is suggested to closely monitor maternal blood pressure and conduct routine prenatal examination. The basic information of pregnant women, medical and obstetric history, physical examination information, ultrasonic examination data, serum markers (PlGF, sFlt-1) test results, pre-eclampsia risk assessment results, medication history and so on were registered in the study. For high-risk pregnant women (PlGF\<100pg/ml or sFlt-1/PlGF ≥ 38), we should pay close attention to the changes of maternal blood pressure and proteinuria. Dynamic monitoring of PlGF or sFlt-1/PlGF should be carried out when necessary, and baseline information should also be registered after joining the group.
