ROTEM analysis after protamine. In HEPTEM, coagulation is activated as in INTEM (via the contact phase). In HEPTEM, however, the addition of heparinase in the reagent degrades heparin present in the sample. The comparison of INTEM and HEPTEM allows for a specific detection of a heparin effect. The clotting time (CT) in HEPTEM as compared to INTEM is not shortened, indicating no residual heparin effect
