A laboratory evaluation into the short activated partial thromboplastin time

Blood Coagulation & Fibrinolysis, 2010
Although short activated partial thromboplastin times (APTTs) are generally considered to be laboratory artefacts of problematic blood collections, there is mounting evidence that in some cases a short APTT may reflect a hypercoagulable state, potentially associated with increased thrombotic risk and adverse cardiovascular events.

Prolonged partial thromboplastin time: To mix or not to mix – is that the question?

Transfusion and Apheresis Science, 2019
Routine mixing studies are frequently used to evaluate patients presenting with prolonged partial thromboplastin times (PTT) and/or prothrombin times (PT). Unfortunately, mixing studies have a number of inherent limitations including lack of standardization in terms of what defines normal pooled plasma (NPP), the processing of a patient's plasma for ...

Prothrombin Time and Activated Partial Thromboplastin Time

2009
Publisher 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

Performance guidelines for the partial thromboplastin time test

La Ricerca in Clinica e in Laboratorio, 1989
The partial thromboplastin time (PTT) test is widely used as a screening test for the detection of hemophilia. It is also used to monitor patients on heparin anticoagulation. These proposed guidelines for the performance of this test, including comparable reference ranges, precision and sensitivity requirements are felt to be reasonable and attainable.

Use of Micro Partial Thromboplastin Time Test

JAMA, 1964
To the Editor:— Dr. J. B. Miale is to be congratulated on his excellent study ( JAMA 185 :752 [Sept 7] 1963) of the value of the partial thromboplastin time (PTT) as a screening test. His introduction of the strikingly reliable micro technique will be welcomed in pediatric practice. But, I will challenge Dr. Miale on one major point. His main thesis
