TEG® parameters [modified from (57)].

Thromboplastic parameters	Description
R: Reaction time (minutes)	Time of latency from start of test to initial fibrin formation (amplitude of 2 mm); i.e., initiation time
α angle: (slope between the traces represented by R-time at 2 mm and K-time at 20 mm) (degrees)	The angle measures the speed at which fibrin build up and cross linking takes place, hence assesses the rate of clot formation; i.e., thrombin burst
MA: Maximal amplitude (mm)	Maximum strength/stiffness of clot. Reflects the ultimate strength of the fibrin clot; i.e., overall stability of the clot
MRTG: Maximum rate of thrombus generation (Dyn·cm−2·s−1)	The maximum velocity of clot growth observed or maximum rate of thrombus generation using G, where G is the elastic modulus strength of the thrombus in dynes·cm−2
TMRTG: Time to maximum rate of thrombus generation (minutes)	The time interval observed before the maximum speed of the clot growth
TTG: Total thrombus generation (Dyn·cm−2)	The clot strength: the amount of total resistance (to movement of the cup and pin) generated during clot formation. This is the total area under the velocity curve during clot growth, representing the amount of clot strength generated during clot growth
