PGF and preeclampsia: Extensive research has now established the feasibility of the first-trimester prediction of about 90% of cases of early preeclampsia (PE) before 32 weeks, 75% of preterm PE before 37 weeks, and 45% of term PE by combining maternal characteristics and medical history with maternal serum placental growth factor (PlGF), the uterine artery pulsatility index (UtA-PI) and mean arterial pressure (MAP) [7,8].
