What does ACT stand for?

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.

Subsequent heparin dose was adjusted by activated clotting time with a target of 200-250ms.

UF heparin activity is normally assessed by a conventional clotting test such as the activated partial thromboplastin time (APTT), thrombin clotting time or activated clotting time.

Out with the old, in with the new Since the mid 1980s, laboratory employees at Baptist Memorial Hospital East have used the Hemochron Activated Clotting Time (ACT) to monitor heparinization during cardiac catheterization and open heart surgery as well as to determine the best time for femoral sheath removal in the critical care unit (see "The importance of the ACT test," page 32).

The next tests most commonly performed at the point of care were activated clotting time (ACT) (65%) and fecal occult blood (63%).

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.

The ENOX test is thus analogous to use of the activated clotting time, or ACT, in determining the effects of treatment with unfractionated heparin during PCI.

In the catheterization laboratory and operating rooms, the activated clotting time (ACT) is commonly used to monitor unfractionated heparin anticoagulation levels.
