Maternal serum <scp>sFlt</scp>‐1/<scp>PlGF</scp> ratio in twin pregnancies with and without pre‐eclampsia in comparison with singleton pregnancies

Abstract

Significant differences in the serum marker levels in singleton vs twin pregnancies were detected. Reference ranges of sFlt-1, PlGF and their ratio in singleton pregnancies are therefore not transferable to twin pregnancies.
