Correlation of Individual Thromboelastography Parameters with Phases of Hemostasis and Standard Hemostatic Laboratory Tests

Thromboelastography parameter	Correlations with physiologic phase of hemostasis	Correlations with standard hemostatic laboratory tests
Reaction time (min)	Time between initiation of coagulation cascade to initial formation of fibrin	INR, aPTT, procoagulant factor levels
Kinetic time (min)	Time between initial formation of fibrin to specific clot firmness (20 mm)	Fibrinogen, platelet count
α-angle (degrees)	Rate of fibrin formation and crosslinking	Fibrinogen, platelet count
Maximum amplitude (mm)	Maximum clot strength	Fibrinogen, platelet count
Lysis-30 (%)	Fibrinolysis 30 minutes after maximum amplitude	Fibrin degradation products

aPTT=activated partial thromboplastin time; INR=international normalized ratio.
