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...

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.

Effect of Warfarin on the Activated Partial Thromboplastin Time
Drug Intelligence & Clinical Pharmacy, 1986Outpatients followed in an anticoagulation clinic were studied retrospectively to determine the effect of warfarin on the activated partial thromboplastin time (APTT). Twenty-nine patients were studied in part 1 of the trial to determine whether their APTT values were elevated when their prothrombin time (PT) was within 1.5 to 2.5 times the control PT.

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”.

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.

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 Effect of Increased Contact Activation Time on the Activated Partial Thromboplastin Time
American Journal of Clinical Pathology, 1976With the kaolin-cephalin activated partial thromboplastin time technic, the plasmas of persons who have Fletcher factor deficiency have shown considerable shortening of clotting times when contact activation has been lengthened from 3 (PTT-3) to 10 minutes (PTT-10).

Comparison of Several Activated Partial Thromboplastin Time Methods
American Journal of Clinical Pathology, 1975Activated partial thromboplastin times (APTT's) performed with a semi-automated electrical-conductivity type of clot timer on plasmas from patients with hepatic disease and intravascular coagulation, and on warfarin or heparin therapy, were significantly lower than when done on the same plasmas with either a manual optical method or an automated ...

Prolonged activated partial thromboplastin time with no clear explanation
Blood Coagulation & Fibrinolysis, 2020Evaluation of bleeding risk before operation includes history of bleeding, complete blood count and basic coagulation tests, prothrombin time and activated partial thromboplatin time (aPTT).
