Thromboelastograph Patterns Under Various Conditions of Coagulopathy and Platelet Inhibition

Conditions	R time [4.6 – 9.1 min]	CK MA[52 – 69 mm]	Heparinase R time[4.3 – 8.3 min]	Rapid TEG MA[52 – 70 mm]	FF[15 – 32 mm]
HYPER-coagulable	↓	↑↑	↓	↑↑	↑↑
HYPO-coagulable	↑	↓	↑	↓	↓
UFH infusion	↑	↓/normal	normal
Argatroban infusion	↑	↓/normal	↑
Conditions			MA-ADP    [45 – 69 mm]		% inhibition  [0 – 17 mm]
Inadequate platelet inhibition			normal, ↑		< 30%
Adequate platelet inhibition			↓ (< 45 mm)		↑↑ (> 30%)

R = reaction time; CK MA = citrate-kaolin maximum amplitude; Rapid TEG MA = maximum amplitude under tissue factor activator; FF = functional fibrinogen; UFH = unfractionated heparin, ADP = adenosine diphosphate. MA-ADP represents clot strength in the presence of P2Y12 adenosine diphosphate-receptor blocker (e.g., clopidogrel, prasugrel).
