Kaolin clotting time (KCT) is a sensitive test to detect lupus anticoagulants. There is evidence that suggests it is the most sensitive test for detecting lupus anticoagulants. It can also detect factor VIII inhibitors but is sensitive to unfractionated heparin as well. The KCT on whole blood is known as the "Activated Clotting Time" (ACT) and is widely used in various instruments during surgery such as cardiac bypass to monitor heparin.

WebbAbstract. Activated partial thromboplastin time (PTT) is a routine coagulation screening test that is sensitive to declines of activities of factors II, V, VIII, IX, XI, XII, kallikrein, high-molecular-weight kininogen, and reduced concentration of fibrinogen. It is also utilized to monitor heparin therapy and some other anticoagulant drugs. WebbThromboelastography (TEG) is a whole-blood viscoelastic test, which attempts to capture a large degree of information about a patient’s bleeding status. Unlike standard laboratory tests for coagulation, TEG is performed in the presence of platelets as well as other blood factors that may affect clotting typically removed by centrifugation.
