<unk> is used to identify acute coagulopathies in both traumatic and nontraumatic patients. This may enable focused use of blood products during resuscitation.
Quantifies the interaction of platelets with the coagulation cascade (aggregation, clot strengthening, fibrin cross linking and fibrinolysis).
0.36mL of clotted blood from the patient is spun in a small cup with changes in the clot strength recorded electrically.
Two commercial types of viscoelastic tests are available:<unk> =TEG
Rotational thromboelastogram = ROTEM
Heparinase to deactivate heparin is now employed in the TEG(r) technology to prevent interference from heparin in samples<unk> =TEG
