Coagulation parameters measured by viscoelastic testing
| Coagulation parameter measured . | ROTEM . | TEG . |
|---|---|---|
| Coagulation proteins (contact and/or tissue factor pathways) | Clotting time | R value (reaction time) |
| Thrombin and fibrin generation; fibrin cross-linking | α angle and clot formation time | K value and α angle |
| Platelet binding of fibrin and cross-linking by factor XIII | Maximum clot firmness | Maximum amplitude |
| Fibrinolysis | Clot lysis | LY30 (lysis at 30 min) |
