Schematic representation of the variable delta (D; min; black arrow), which can be calculated from the difference between the reaction time (R; min; dotted arrow), i.e., the time from initiation of coagulation until the amplitude of the conventional TEG tracing reaches 2 mm and the split point (SP; min; longer black arrow), i.e., the time from starting the coagulation process until divergence of the TEG tracings from the zero line. The delta value = R - SP
