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.

LP15959-7   Clotting time
Time until 2 mm clot firmness has been achieved after the test has been started. Source: Regenstrief Institute

LP15959-7   Clotting time
Clotting time is the time required for a sample of blood to coagulate in vitro under standard conditions. There are various methods for determining the clotting time, including manual methods such as Lee White and Sukharev, thromboelastography, and heparin protamine titration. Source: Regenstrief LOINC
