The Hemochron Response uses the same principle to measure the INR and the APTT as it does to measure the activated clotting time.
Indeed, several previous studies have demonstrated that activated clotting time values are known to be very method dependent (5, 7-10).
Further doses of heparin, 50 to 100 mg IV were given as necessary during CPB to maintain the kaolin activated clotting time (ACT) (Hemochron 401, Edison, NJ, U.
At present, the use of heparin during CPB is typically monitored by clotting-time measurements, the most common and widely used one being the activated clotting time (ACT).
Monitoring of any laboratory test for a DTI did not change from the early period to the late period, with the exception of activated clotting time, which increased in use over time (5.
The activated clotting time, or ACT, test has been an accepted POCT for about 30 years.
The activated clotting time (ACT) is the most commonly used method for monitoring heparin anticoagulation during CPB, based on ease of use and a few early studies that demonstrated a reduction in postoperative bleeding when the ACT was used to monitor heparin and protamine therapy.
Cascade POC assays include prothrombin time (PT)--whole blood or citrated; activated partial thromboplastin time (APTT), celite activated clotting time (ACT), Enox test--low molecular-weight heparin, with additional assays in development.

In this test, MC-45308 compared favourably to both bivalirudin and argatroban, by prolonging the activated clotting time further when used at the same concentration.
