Brief Summary

The ClotPro analyzer is a new generation viscoelastic analyzer for the in vitro assessment of blood coagulation. This study aims to assess the agreement of ClotPro 6.0, ROTEM delta, and TEG 6s in three distinct cohorts: i) patients with liver disease undergoing liver surgery, ii) pregnant women undergoing elective cesarean section, and iii) patients undergoing elective intracranial neurosurgery. Further coagulation tests will be performed (standard laboratory coagulation tests, thrombin and plasmin generation tests) in an exploratory fashion to compare them with viscoelastic test results. The obtained test results will not result in any diagnostic or therapeutic consequences for patients included in this study.
