Brief summary
The study aims to investigate the impact of preeclampsia on hemostasis.
Detailed description
In comparison to healthy pregnant women and non-pregnant woman, this study analyses parameters of primary hemostasis and plasmatic coaguation in preeclamptic pregnant woman. Detailed analyses of the platelet function is performed using the Multiple Electrode Aggregometry, detailed analyses of the plasmatic coagulation syste is performed by isolated coaguation factor analyses and conventional coagulation analyses.
Interventions
Multiple Electrode Aggregometry using the Multiplate system Coagulation factor analyses (FXIII, FVIII, vWF) Parameters of conventional coagulation testing (aPTT, INR, Platelet count)
