Activated partial thromboplastin time.

Methods in molecular biology, 2013
Activated partial thromboplastin time (APTT) is a commonly used coagulation assay that is easy to perform, is affordable, and is therefore performed in most coagulation laboratories, both clinical and research, worldwide. The APTT is based on the principle that in citrated plasma, the addition of a platelet substitute, factor XII activator, and CaCl2 ...

How to Optimize Activated Partial Thromboplastin Time (APTT) Testing: Solutions to Establishing and Verifying Normal Reference Intervals and Assessing APTT Reagents for Sensitivity to Heparin, Lupus Anticoagulant, and Clotting Factors

Seminars in Thrombosis and Hemostasis, 2019
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 ...

Activated Partial Thromboplastin Time

Scandinavian Journal of Haematology, 1981
An internationally standardized preparation and 10 commercial kits widely used to perform the activated partial thromboplastin time (APTT) were compared in 4 laboratories for the purpose of assessing their ability to detect mild deficiencies of factor VIII activity.
