TP, APTT and fibrinogen reference values in healthy beagle breed dogs


Background: Hemostasis is a process of blood coagulation with the function of preventing hemorrhagic processes in the organism. The Coagulation Time (CT), Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT), Fibrinogen, Thrombin Time (TT), Increased Fibrin Degradation Products (IFDP) and D-Dimers are laboratory tests that can be used to evaluate the coagulation cascade. Objectives: The present study aimed to determine the reference values of PT, APTT and Fibrinogen by semi-automatic methodology with laboratorial kits. Methods:  Blood samples were collected from 22 healthy beagle dogs and immediately centrifuged and citrated plasma stored at -20ºC for posterior analysis. PT, APTT and fibrinogen were measured using commercial kits in a semi-automatic coagulometer by the viscosity detection system.  Results: Mean values obtained were 6.0 ± 7.3 seconds for PT, 8.4 ± 16.9 seconds for APTT, and 10.2 ± 26.4 seconds for Fibrinogen. Conclusion: It is concluded that the values obtained in this work can be used as reference for healthy Beagles.
