The McNemar test was used for the analysis between the reference ranges determined in our study and provided by manufacturers. R (s), K (s), Angle (α), maximum amplitude (MA, mm) and lysis at 30 min (LY30, %).

Abbreviation(s): A/A, abnormal data evaluated by both methods; A/N, abnormal data evaluated by this study, normal data evaluated by manufacturers; N/A, normal data evaluated by this study, abnormal data evaluated by manufacturers; N/N, normal data evaluated by both methods; TEG, thromboelastograph.
