1 sty 2022 · Results: The reference range of coagulation screening in our study was established as the following values: PT: 10.7–15.3 s, APTT: 26.8–41.2 s, TT: 12.8–21.7 s, and fibrinogen: 223–372 mg/dl.
1 sty 2021 · Reference ranges for PT and aPTT using CWB were 12.2 to 16.8 seconds and 72.5 to 100.3 seconds, respectively. Activated clotting time in NAWB was 71+/-11.8 seconds.
The APTT and/or PT are prolonged in 50%–85% of dogs with severe liver disease, meaning that the factor activity is 30% of normal. Nevertheless, 2% actually develop hemorrhage and, when bleeding does occur, it is usually associated with concurrent disease.
Dogs with low concentrations of factor VII will have normal aPTT, with prolonged PT. Depending on the results of coagulation testing, further investigations may involve specific analysis to determine the activities of individual coagulation factors.
The aim of the current study was to determine canine reference intervals for prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen, and antithrombin (AT) according to international recommendations.
The PT is a unitized coagulation test intended for in vitro use in performing a quantitative, one-stage prothrombin time. The PT test is performed using fresh canine, feline, or equine whole blood. This test is to be used with the Coag Dx* Analyzer and is also compatible with the SCA2000* Coagulation Analyzer.
