The EAT could detect small changes both in the hyper- and hypo-coagulation, and the measurement range of the EAT was between dilutions of the TF reagent of ×10−2 to ×10−4 for the hypercoagulability, and between concentrations of heparin of 0 and 0.15 U/ml for the hypocoagulability. Here, TF is linked to thrombophilia.
