Clotting time.extrinsic coagulation system activated of Blood by Rotational TEG
Active
Term Description
CT (Clotting time): The CT is the latency time from adding the start reagent to blood until the clot starts to form. Prolongation of CT may be a result of coagulation deficiencies, primarily coagulation factors, or heparin (dependent on the test used). A potential contribution of heparin can be detected by comparing INTEM- with HEPTEM CT data (see "reagents" below). A shortening of CT indicates hypercoagulability.

Part Description
LP270303-3 Thromboelastography.rotational
Rotational thromboelastography, also called thromboelastometry or ROTEM, is similar to traditional thromboelastography (TEG) in that it is used to measure the viscoelastic properties of a clot. In TEG, whole blood is added to a cup in which a pin is suspended, the cup is rotated, and as the clot forms, the rotational force is transferred to the pin. The movement of the pin is transformed into a tracing, from which the clotting parameters are derived. In ROTEM, the cup is stationary and the pin rotates, and as the clot forms, the rotation of the pin slows down. The torsion of the pin is transformed into a tracing from which the ROTEM parameters are derived. PMID: 22726088
