Activated clotting time (ACT) of Blood induced by Diatomaceous earth
Active
Term Description
This is a point-of-care electrochemical assay that measures venous or arterial whole blood activated clotting time (ACT) by using a Celite clot activator, which stimulates the intrinsic coagulation pathway. Celite is the commonly-used brand name of the diatomaceous earth (a naturally occurring, soft, siliceous sedimentary rock) used in ACT assays. Different activators result in different clotting times. For example, the ACT reference ranges for glass, kaolin and Celite are 110-190 sec, 90-150 sec and 100-170 sec, respectively. http://www.practical-haemostasis.com/Miscellaneous/Miscellaneous%20Tests/act.html In addition, aprotinin may affect the ACT result when Celite is used, therefore, the test is not recommended for use with patients receiving aprotinin. The ACT is primarily used to monitor a patient's state of anticoagulation due to heparin that is administered during a medical or surgical procedure. It is commonly employed in cardiac catheterization, percutaneous transluminal coronary angioplasty (PTCA), renal dialysis, hemodialysis, and extra-corporeal circulation during bypass. This term was created for, but not limited in use to, the submitter's Abbott Celite activated clotting time test kit.
Part Description
LP207644-8 Activated clotting time
The activated clotting time (ACT) measures the time to clot formation after addition of an activator, and is used primarily to monitor a patient's coagulation status during surgery, especially procedures during which patients are on cardiopulmonary bypass. The activator may stimulate the intrinsic and/or extrinsic coagulation pathway, and commonly used activators include kaolin, Celite and glass beads. Various anticoagulant drugs can be used to prevent clot formation and consumption of platelets during surgery. The most common is unfractionated heparin because it has a short half-life and is easily reversed. Baseline ACT and subsequent ACT measurements during and after the procedure help determine the initial heparin dose and titration parameters to achieve a stable level of anticoagulation during surgery, as well as appropriate reversal of anticoagulation after surgery. The ACT can be affected by platelet count, platelet function, temperature of the blood, and acquired or inherited hematologic conditions. The ACT is a point of care test used to monitor patients receiving high doses of heparin in an acute setting, while partial thromboplastin time (PTT) is used to monitor patients who are on lower, long-term therapeutic doses of heparin.
