A representative TEG® tracing obtained during the clotting process of whole blood of a normal subject. The shaded area represents the corresponding first derivative or velocity of the waveform produced by the TEG® system. Several parameters corresponding to the rate of development of the tensile strength of the forming clot are derived from the first derivative of the waveform.
The parameters are:
MTG – Maximum Rate of Thrombus Generation (100*mm/sec)
TTG – Total Area Under the Curve; Measures Total Thrombus Generation (mm)
TMG – Time to Maximum Rate of Thrombus Generation (sec)
