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.
Specialty. Hematology. Heparin-induced thrombocytopenia ( HIT) is the development of thrombocytopenia (a low platelet count), due to the administration of various forms of heparin, an anticoagulant. HIT predisposes to thrombosis (the abnormal formation of blood clots inside a blood vessel ). When thrombosis is identified the condition is called ...
Reptilase time. Reptilase time ( RT) is a blood test used to detect deficiency or abnormalities in fibrinogen, [1] [2] especially in cases of heparin contamination. Reptilase, an enzyme found in the venom of Bothrops snakes, has activity similar to thrombin. Unlike thrombin, reptilase is resistant to inhibition by antithrombin III.
Activated protein C resistance ( APCR) is a hypercoagulability (an increased tendency of the blood to clot) characterized by a lack of a response to activated protein C (APC), which normally helps prevent blood from clotting excessively. This results in an increased risk of venous thrombosis (blood clots in veins), which resulting in medical ...
MeSH. D013918. [ edit on Wikidata] The thrombin time ( TT ), also known as the thrombin clotting time ( TCT ), is a blood test that measures the time it takes for a clot to form in the plasma of a blood sample containing anticoagulant, after an excess of thrombin has been added. [ 1] It is used to diagnose blood coagulation disorders and to ...
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 ...
The prothrombin time ( PT) – along with its derived measures of prothrombin ratio ( PR) and international normalized ratio ( INR) – is an assay for evaluating the extrinsic pathway and common pathway of coagulation. This blood test is also called protime INR and PT/INR. They are used to determine the clotting tendency of blood, in such ...
Fidelity’s 2023 Retiree Health Care Cost Estimate found that people who retire at 65 can expect to spend $157,500, on average, for health care and medical expenses throughout their retirement ...
