Standardization of coagulometric tests in griffon vultures (Gyps fulvus): PT, aPTT and factor V reference values

Abstract

Griffon vultures are frequently admitted to wildlife rehabilitation centers with coagulation disorders due to lead or rodenticide poisoning. These disorders are challenging to diagnose due to the absence of reference intervals and validated coagulometric measurement protocols. The aim of this study was to standardize the measurement of prothrombin time, activated partial thromboplastin time, and coagulation factor V in griffon vultures using diagnostic reagents from human medicine, while also analyzing for differences according to sex, cause of admission, and weight.
