From: Assays of different aspects of haemostasis – what do they measure?

TEG ROTEM ReoRox
KaolinTEG InTEM HepScreen1
Kaolin (intrinsic pathway activation) Intrinsic pathway activation, sensitive to heparin TP (extrinsic pathway, sensitive to heparin)
HepTEG HepTEM HepScreen2
Heparin neutralising cup Intrinsic pathway activation + heparin neutralisation TP (extrinsic pathway + heparin neutralization)
RapidTEG ExTEM FibScreen1
Kaolin + TF activation TF activation (extrinsic pathway) TP (extrinsic pathway)
Functional fibrinogen TEG (FFTEG) FibTEM FibScreen2
TF activation + platelet inhibition with abciximab TF activation + platelet inhibition with cytochalasin TP activation + platelet inhibition with abciximab)
FibTEM+
TF activation + platelet inhibition with cytochalasin and tirofiban (under development)
Platelet Mapping Kit ApTEM ReoTrap
(ADP, AA) (TF activation + aprotinin, verification of fibrinolysis) PAR-1 activation
