The Control Of Heparin Administration By The Activated Partial Thromboplastin Time(APTT)
Thrombosis and Haemostasis, 1981The UK National Quality Control Trials have previously shown that the various APTT methods differ in their ability to detect low levels of heparin (Poller et al 1980). UK and US proficiency surveys have also shown lack of linearity of some APTT methods over a range of heparin concentrations.

Background: The formation of thrombus in the performance of APTT can be visualized in graphical form (as wave) and the study of wave (waveform analysis) provides information on hemostasis. An abnormal form of the curve, biphasic, was associated with disseminated intravascular coagulation (DIC) and sepsis, caused by the in vitro Ca + +−dependent ...

A 69-year-old man of Jewish descent with a second local relapse of rectal carcinoma was found to have a markedly prolonged activated partial thromboplastin time (aPTT). Further evaluation revealed a homozygous factor XI deficiency. Despite various operations in the past he had never displayed any bleeding problems.

DTW. Deutsche tierarztliche Wochenschrift, 1993
The factor VIII:C-sensitivity of the aPTT in dogs was investigated for 2 different, commercially available reagents. For this purpose, 45 plasmas with a decreased factor VIII:C-activity, which were collected from haemophilic dogs (n = 10) at variable points of time of a substitution therapy were used.
