A measure of the time taken for clot formation.
The time taken in Quick test for clotting to take place.
A laboratory test performed to identify the time that is needed for clotting after thromboplastin and calcium are added to decalcified plasma.
A kind of blood test, often considered one of the liver function tests, which can also indicate vitamin K deficiency and help physicians monitor use of anticoagulant (anti-blood-clotting) medicine.
Time required for clot formation in plasma, a measure of the activity of several coagulation factors.
The time it takes for clotting to occur after thromboplastin and calcium are added to decalcified plasma. The test is used to assess levels of anticoagulation in patients taking warfarin, to determine the cause of unexplained bleeding (e.g., in patients with hemophilia), or to assess the ability of the liver to synthesize blood-clotting proteins.
A type of blood coagulation test, the transformation of prothrombin into thrombin is a chemical reaction central to the blood clotting process. This reaction relies on the presence of clotting factors, calcium, and thromboplastin. When calcium and thromboplastin are introduced to a blood sample, clotting should occur within a specific timeframe. A clotting time that is excessively delayed indicates insufficient clotting factors, as observed in certain liver disorders and vitamin K deficiency. Prothrombin time tests are employed to monitor individuals undergoing warfarin treatment, an anticoagulant medication.
The time it takes for oxylated plasma to clot upon the addition of thromboplastin is measured in seconds. This duration is inversely related to the amount of prothrombin present.
