P–380 Differential concentrations of maternal and fetal hemopexin and α1-microglobulin in preeclampsia from IVF pregnancies depending on the presence of corpus luteum at embryo transfer

Study question Does the presence of corpus luteum (CL) in in vitro fertilization (IVF) treatments affect maternal and fetal concentrations of hemopexin and α1-microglobulin in preeclampsia? Summary answer Decreased hemopexin and increased α1-microglobulin levels in maternal and fetal blood in IVF pregnancies with absence of CL particularly in pregnancies complicated by preeclampsia. What is known already: Pregnancies after frozen embryo transfer...
