Levels of Maternal Serum Angiogenic Factors in Third-Trimester Normal Pregnancies: Reference Ranges, Influence of Maternal and Pregnancy Factors and Fetoplacental Doppler Indices

<b><i>Aim:</i></b> To establish normal ranges of maternal placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFlt-1) and sFlt-1/PlGF ratio at 32-41 weeks' gestation and to evaluate the influence of maternal characteristics, and of fetoplacental Doppler. <b><i>Material and Methods:</i></b> Serum levels of PlGF, sFlt-1 and sFlt-1/PlGF ratio were measured in 300 noncomplicated...
