The sFlt-1 /PlGF ratio in PE and chrHBP with PE were significantly higher than GH & chrHBP, in which early-onset were higher. For gestatioanl hypertension, sFlt-1 /PlGF ratio> 36.44 could rule in PE occurence(AUC=76.17% - 78.39%) in 1-4week with PPV 0.91-0.94 & NPV 0.67 before 34 weeks, while sFlt-1 /PlGF ratio< 51.52 could rule out PE occurrence (AUC=75.29% - 78.39%) in 1-4 weeks with NPV 0.91-0.96 & PPV 0.62-0.73 after 34 weeks. For chronic hypertension, sFlt-1 /PlGF ratio> 47.78 could rule in PE occurrence (AUC=82.5% - 86.36%) in 1-4 weeks with PPV 0.9-0.96 & NPV 1.0 before 34 weeks, while sFlt-1 /PlGF ratio< 28.61 could rule out PE occurence(AUC=72.41% - 73.03%) in 1-4 weeks with NPV 0.88 & PPV 0.43-0.79 after 34 weeks.
