WebAll ACT tests activate the intrinsic coagulation pathway, accelerate fibrin formation, and produce a shorter clotting time versus nonmanipulated blood samples. However, the Hemochron Signature Elite system, including its maximally activated reagents for ACT+ and ACT-LR, produces significantly shorter clotting times than do other systems. WebThe extrinsic pathway is turned off; the measured PT will be high, but blood can still clot via the intrinsic pathway. If there is no protein C, the normal inhibition mechanism of the intrinsic pathway is turned off. This means there is an increased tendency to clot via the intrinsic pathway.
