PGF and preeclampsia: Statistical analysis of outcomes was conducted using sFlt-1/PlGF categories ≤ 33, > 33 to < 85, and ≥ 85, with results from the study indicating that women at highest risk were correctly hospitalized after the sFlt-1/PlGF test, and that the risk for preeclampsia-related maternal and fetal outcomes increased along with increasing sFlt-1/PlGF ratios and was highest in women with an sFlt-1/PlGF ratio of ≥ 85 [37].
