NCT05935137

Brief Summary

The primary aim of the study is to determine the physiological parameters of the coagulation status of pregnant women in the peripartum period (PWPP) for the ClotPro® device - Ex-test (CT, CFT, MCF, A5, A10, A20, ML), In-test (CT, CFT, MCF, A5, A10, A20, ML) and Fib-test (CT, CFT, MCF, A5, A10, A20, ML) and based on these results, establish ClotPro® reference ranges in parturients. The secondary aim is to compare the difference in coagulation parameters between pregnant women in the peripartum period and a control group of non-pregnant women (NPW) on the ClotPro® device. Furthermore, a comparison with the physiological parameters of pregnant women in the peripartum period intended for ROTEM® and TEG® devices (they are already known).
