The multiple faces of the partial thromboplastin time APTT

A further face of the partial thromboplastin time APTT.

Influence of sex on activated partial thromboplastin time (aPTT) and prothrombin time (PT) in sheep.

Haemostasis is a physiological process that prevents excessive blood loss. In laboratory, the prothrombin time (PT) and the activated partial thromboplastin time (aPTT) are used to examine clotting systems. However, the influence of sex on PT and aPTT values is unknown. The present work aimed to determine the values for PT and aPTT in adult sheep and to evaluate their dependence on the sex of t...

Evaluation of activated partial thromboplastin time (aPTT) reagents for application in biomedical diagnostic device development.

INTRODUCTION The most commonly used test for monitoring heparin therapy is the activated partial thromboplastin time (aPTT). The response of available aPTT reagents to heparin varies significantly. The aim of this study was to highlight the differences between aPTT reagents stored in a dried format to select the most suitable formulations to be used for the development of point-of-care diagnost...

Determination of Biological Activity of Recombinant Reteplase Using Clot Lysis Time and Activated Partial Thromboplastin Time (APTT) Lysis Methods: A Comparative Study

Recombinant plasminogen activator (reteplase) is a third generation thrombolytic agent which has been used on coronary artery thrombosis and acute myocardial infarction. Clot lysis assay is usually considered as a unique method to evaluate biological activity of reteplase. In this study biological activity of reteplase was determined by APTT (activated partial thromboplastin time) lysis method....
