Table 2 Evaluated TEG coagulation parameters
Coagulation parameter | Description |
|---|---|
R-time (R) | The time from the start of a sample run until the first significant levels of detectable clot formation in minutes (min). |
K-time (K) | The time from the measurement of R until a fixed level of clot firmness is reached (Amplitude = 20 mm) in minutes (min). |
Angle (α) | An indicator of the kinetics of clot formation and fibrinogen level quantified in degrees (º). |
Maximum Amplitude (MA) | A measurement of maximum strength or stiffness of the developed clot in millimeters (mm) and an indicator of platelet function. |
Shear Elastic Modulus Strength (G) | A measurement of clot strength calculated as G = (5000A/(100-A))/1000 and reported as dynes per square centimeter (d/sc). |
Time to MA (TMA) | The time until the maximal clot strength (MA) is reached in minutes (min). |
