Approach to thromboelastography-based transfusion in cirrhosis: An alternative perspective on coagulation disorders

Table 4 Various types of thromboelastography assays

TEG channel	Activator	Function
Native TEG	None	Theoretically most sensitive to subtle coagulopathic changes and hyperfibrinolysis
Conventional TEG	Kaolin	Activates clotting cascade to expedite results
Rapid TEG	Tissue factor + kaolin	Activates clotting cascade to expedite results
Functional fibrinogen TEG	Glycoprotein IIb/IIIa inhibitor	Inhibits platelets to isolate the contribution of fibrinogen
Heparinase TEG	Heparinase	Inhibits heparin; the presence of heparin (endogenous or exogenous) is suggested when this channel shows improved clotting compared to other channels
