Extremely Shortened Activated Partial Thromboplastin Times
JAMA: The Journal of the American Medical Association, 1980To the Editor.— The presence of a hypercoagulable state in patients with a shortened activated partial thromboplastin time (APTT) as manifested by the clinical association with an increased incidence of thromboembolic disease has previously been reported by Hume, 1 Gallus et al, 2 Pilgeram, 3 McKenna et al, 4 and McKenna et al.

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.

Prothrombin Time and Partial Thromboplastin Time Assay Considerations
Clinics in Laboratory Medicine, 2009Prothrombin times and activated partial thromboplastin times have long been used as tests of overall ("global") clotting function. Laboratory coagulation testing issues should be at the forefront of the reader's consciousness whenever critically evaluating and extrapolating published study conclusions reliant on the results of these tests.

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.

Pseudo-prolongation of the Partial Thromboplastin Time
American Journal of Clinical Pathology, 1983A patient with a negative personal and family history for bleeding was being prepared for bronchoscopy when an extremely long activated partial thromboplastin time was detected. Analyses for the contact phase factors were normal. It was determined subsequently that the prolongation was artifactual.

Prothrombin and Partial Thromboplastin Time
2016Basic plasma coagulation function is readily assessed with a few simple in vitro laboratory tests, prothrombin time (PT) and partial thromboplastin time (PTT), and they are useful as the current standard for establishing a diagnosis of coagulopathy.

Use of the Activated Partial Thromboplastin Time
Annals of Internal Medicine, 1988Excerpt To the Editor:In connection with a recent article (1), I pose a question. Should peridural anesthesia in women with otherwise normal bleeding history be preceded by coagulation tests to pre...
