An Assessment of Clinical Interchangeability of TEG® and RoTEM® Thromboelastographic Variables in Cardiac Surgical Patients

Abstract

The TEG and RoTEM measurements demonstrated a close correlation for the MA, but the alpha did not for the R and K variables. The kaoTEG had the best agreement with the exTEM measurement. Therefore TEG and RoTEM measurements are not completely interchangeable, and the clinical interpretation of thromboelastograhic data should be used with caution.
