Correlation Between Activated Clotting Time and Activated Partial Thromboplastin Times
The Annals of Pharmacotherapy, 2002OBJECTIVE: To evaluate the correlation between clotting time tests and heparin concentration, the correlation between activated clotting time (ACT) and activated partial thromboplastin time (aPTT) results, and to compare the clinical decisions based on ACT results with those based on aPTT results.

The Activated Partial Thromboplastin Time
Annals of Internal Medicine, 1986Excerpt To the editor: The statement by Drs. Suchman and Griner (1) that "normal APTT [activated partial thromboplastin time] and PT [prothrombin time] results essentially rule out a significant co...

Erroneous Activated Partial Thromboplastin Time
Annals of Internal Medicine, 1978Excerpt To the editor: We wish to draw attention to the problem of erroneous results of activated partial thromboplastin times (aPTT) when plasma samples from patients on heparin are tested with th...

Activated Partial Thromboplastin Time
Scandinavian Journal of Haematology, 1981An internationally standardized preparation and 10 commercial kits widely used to perform the activated partial thromboplastin time (APTT) were compared in 4 laboratories for the purpose of assessing their ability to detect mild deficiencies of factor VIII activity.

Activated Partial Thromboplastin Time
2013Activated partial thromboplastin time (APTT) is a commonly used coagulation assay that is easy to perform, is affordable, and is therefore performed in most coagulation laboratories, both clinical and research, worldwide. The APTT is based on the principle that in citrated plasma, the addition of a platelet substitute, factor XII activator, and CaCl2 ...

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.

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.

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.

Spurious Prolongation of the Activated Partial Thromboplastin Time
Thrombosis and Haemostasis, 1977SummaryThe clinical and laboratory data of 8 patients (4 males and 4 females) with circulating anticoagulant were presented. Based on prolonged APTT, failure to correct the APTT with 50 % normal plasma and abnormal tissue thromboplastin inhibition test, the inhibitor was identified as “middle stage” – or the “lupus anticoagulant”.
