Value of soluble fms-like tyrosine kinase-1/placental growth factor test in third trimester of pregnancy for predicting preeclampsia in asymptomatic women.

The sFlt-1/PlGF test during 180-259 g.d. detected approximately half of subsequent PE cases. An optimal time to use the test for screening purposes was estimated 225-238 g.d. (DR 66.7%). False positive test results were more common to cases with other adverse pregnancy outcomes and samples drawn at higher gestational age.
