For the prediction of late-onset preeclampsia (PE) in low risk women, the investigators established a cut-off value for sFlt-1/PlGF ratio and evaluated the combination models of Elecys, second trimester uterine artery (UtA) doppler, and fetoplacental proteins for Down syndrome screening.

Primary Outcome Measures:
  • identification of patients at risk for late-onset preeclampsia with sFlt-1/PlGF ratio [ Time Frame: at delivery ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • identification of patients at risk for late-onset preeclampsia with combined biochemical markers [ Time Frame: at delivery ] [ Designated as safety issue: Yes ]

Detailed Description:

A prospective study was carried on in Cha hospital. Serum samples for Down syndrome screening were assayed to estimate pregnancy-associated plasma protein-A (PAPP-A), alpha-fetoprotein , unconjugated estriol, human chorionic gonadotrophin , and inhibin-A. Women screened for Down syndrome were offered UtA Doppler at 20-24 weeks of gestation and then collected serial serum samples for sFlt-1/PlGF ratio at two time points (24-27 and 34-37 weeks' gestation).
