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...

Pseudo-prolongation of the Partial Thromboplastin Time [PDF]
American Journal of Clinical Pathology, 1983 A 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.

Partial Thromboplastin Time for Screening
Annals of Internal Medicine, 1979Excerpt To the editor: We read the report of Robbins and Rose in the May 1979 (1) with an interest heightened by our own experience.

The activated partial thromboplastin time (APTT) assay is a very common coagulation test, used for several reasons. The test is conventionally used for assessing the contact factor (intrinsic) pathway of blood coagulation, and thus for screening ...

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...

International Journal of Laboratory Hematology, 2018
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 ...

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.

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.

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”.
