Although tests of global hemostasis prothrombin time (PT) and activated partial thromboplastin time (aPTT) should not be used for prediction of bleeding risk, these tests are often used by many clinicians in daily practice particularly as a preoperative ...

Therapeutic Drug Monitoring, 2015
Backgroud: Cirrhosis of the liver results in complex hemostatic changes that place patients at risk for both bleeding and thrombotic events. This study evaluates the adverse effects of anticoagulation with unfractionated heparin among patients with ...

Routine Use of the Prothrombin and Partial Thromboplastin Times
JAMA: The Journal of the American Medical Association, 1989The prothrombin time (PT) and activated partial thromboplastin time (APTT) tests are often routinely ordered for hospitalized patients. Ordering patterns and clinical indications for the PT and APTT tests on the medical service at a teaching hospital were studied. Eighty-one percent of all patients admitted to the medical service had a PT and APTT test

Activated Partial Thromboplastin Time and Minor Coagulopathies
American Journal of Clinical Pathology, 1979Five commercially available activated partial thromboplastin time (APTT) test systems were compared with the kaolin partial thromboplastin time (KPTT) method to determine sensitivity in detecting minor coagulation defects. All reagent systems detected severe factor VIII-, IX-, and XI-deficient hemophilia.

The Partial Thromboplastin Time and Factor VIII Therapy
American Journal of Clinical Pathology, 1972A large pseudotumor was removed from a hemophiliac patient, necessitating the use of long-term, high-dose therapy with factor VIII concentrate. The patient's activated partial thromboplastin time rarely normalized in spite of high factor VIII assay levels. In addition, other routine tests of coagulation became abnormal.

Heparin and Partial Thromboplastin Time: an International Survey
British Journal of Haematology, 1980Summary.The reliability of routine partial thromboplastin time (PTT) methods in the measurement of the anticoagulant effect of heparin has been assessed in a study involving over 300 hospitals in the U.K. and overseas. Commercial PTT methods were relatively insensitive to heparin, added in vitro, compared with the standardized PTT method tested by the ...

Perfusion, 2014
Introduction: Historically, the activated clotting time (ACT) has been the preferred monitoring test of the heparin effect in extracorporeal membrane oxygenation (ECMO) patients.

Haemophilia, 2014
Patients with haemophilia (PWH) are usually monitored by the one‐stage activated partial thromboplastin time (aPTT) factor VIII (FVIII) assay. Different aPTT activators may affect clotting time (CT) and FVIII:C levels in patients treated with PEGylated ...

Abnormal activated partial thromboplastin time and malignancy
Scottish Medical Journal, 2011Malignancy often results in clotting abnormalities. The aetiology of haemostasis problems in cancer is complex, and is still not completely understood. We describe a case of a patient with malignant mesothelioma, who was found to have elevated activated partial thromboplastin time, due to lupus anticoagulant.

CONTEXT Elevated free hemoglobin (Hb) and bilirubinemia complicate extracorporeal membrane oxygenation and could affect unfractionated heparin (UH) therapy monitoring by anti-Xa assay and activated partial thromboplastin time (aPTT).
