These samples were provided with the PT, INR and APTT results from 31 laboratories that had tested the samples using the Stago STart 4 (previous model to STart Max).

To increase the sample size, citrated blood samples from additional birds with the same origin were included for analyses of APTT and PT and measurement of fibrinogen levels.
Typical laboratory findings in acquired haemophilia include an isolated prolongation of APTT and a low level of factor VIII.
Thus, it seems likely that elevated prothrombin levels could contribute both to thrombotic risk and to a shortening of the PT and APTT.
In our study we compared the values of APTT and INR in patients operated with the use of CPB (on-pump) and patients operated off-pump.
18 In this study, PT and APTT improved significantly within six hours of vitamin K injection.
Coagulation profile showed isolated prolongation of APTT (66.
