The Activated Partial Thromboplastin Time and Factor Xl Deficiency
Annals of Internal Medicine, 1986Excerpt To the editor: Suchman and Griner (1) recommend that the activated partial thromboplastin time (APTT) not be determined before surgery because an adequate clinical assessment of a possible ...

The activated partial thromboplastin time in early diagnosis of myocardial infarction
Blood Coagulation and Fibrinolysis, 2001Intracoronary thrombosis is fundamental to the pathogenesis of acute myocardial infarction (MI), yet few studies have examined the diagnostic value of routine coagulability markers, such as the activated partial thromboplastin time (aPTT), in patients with chest pain. We hypothesized that the initiation of thrombosis early in MI would shorten the aPTT,

Prothrombin Time and Activated Partial Thromboplastin Time
2009Publisher Summary This chapter discusses the prothrombin time (PT) and activated partial thromboplastin time (PTT) which are two separate but related in vitro laboratory assays that are used to evaluate coagulation factors. Factors involved uniquely in the PTT are referred to as intrinsic pathway factors, whereas factors unique to the PT are referred

Effect of Freezing Heparinized Plasma on the Activated Partial Thromboplastin Time
American Journal of Clinical Pathology, 1974Prior freezing was found to shorten significantly the activated partial thromboplastin times of heparinized plasmas. This shortening was not attributable to release of platelet factor 4 by freeze-damaged residual platelets in these plasmas. Some differences attributable to type of reagent were observed in activated partial thromboplastin times ...

Activated partial thromboplastin time measurements in citrated canine plasma
Journal of Comparative Pathology, 1992Activated partial thromboplastin times (APTT) were determined for citrated plasma samples obtained from healthy Beagle dogs. Significant variations were observed with different reagents and analysers in these studies emphasizing the importance of analytical variables in APTT measurements.

Evaluation of an Automated Method for the Determination of the Activated Partial Thromboplastin Time
American Journal of Clinical Pathology, 1974Activated partial thromboplastin time (APTT) determinations on the Lancer Coagulyzer (a photoelectric clot sensing instrument) were compared with APTT’s obtained by the standard manual method. No statistically significant difference between the Coagulyzer and the manual methods was found when APTT determinations in plasma samples containing various ...

Control of Heparin Therapy With Activated Partial Thromboplastin Times
JAMA: The Journal of the American Medical Association, 1967In vitro and in vivo studies were carried out to determine whether a standardized laboratory procedure, the activated (kaolin) partial thromboplastin time (PTT), could be used to regulate heparin therapy. In vitro, increasing heparin concentrations caused progressive prolongation of both the Lee-White (L-W) coagulation time and the activated PTT ...
