Urinary and Serum Angiogenic Markers in Women With Preexisting Diabetes During Pregnancy and Their Role in Preeclampsia Prediction.

This study prospectively describes the longitudinal changes in urinary PlGF alongside serum angiogenic markers throughout pregnancy in women with preexisting diabetes. We demonstrate correlation between urinary and serum PlGF and that in women with preexisting diabetes in pregnancy, serum PlGF is a better predictor of preeclampsia than the sFLT-1-to-PlGF ratio.
