The test is finished when bleeding has stopped. [6] A prolonged bleeding time may be a result from decreased number of thrombocytes or impaired blood ...
The results of these screening tests, in conjunction with the clinical history (especially bleeding history), will then direct the selection of further, more detailed and specific coagulation tests, such as: specific factor assays, like fibrin degradation products, D-dimer, thrombin time, platelet aggregation, or
Tests in platelet rich plasma (close to real conditions in the body, but restrictions as to the terms of work), Tests in whole blood (the most adjusted to human physiology; the test can be started immediately; but the least convenient due to terms of blood storage and difficulties of the results' interpretation).
The partial thromboplastin time (PTT), also known as the activated partial thromboplastin time (aPTT or APTT), is a blood test that characterizes coagulation of the blood.A historical name for this measure is the Kaolin-cephalin clotting time (KCCT), [1] reflecting kaolin and cephalin as materials historically used in the test.
Activated clotting time (ACT), also known as activated coagulation time, is a test of coagulation. [1] [2]The ACT test can be used to monitor anticoagulation effects, such as from high-dose heparin before, during, and shortly after procedures that require intense anticoagulant administration, such as cardiac bypass, interventional cardiology, thrombolysis, extra-corporeal membrane oxygenation ...
