Reference values for some fundamental haemostatic factors in the dog.

Abstract

The study is a methodological survey to define the reference values for some basic haemostatic parameters in healthy dogs. Reference values for PT, APTT and factors VIII:C and IX:C were studied in 34 dogs. The reference values were (minimum-maximum) 6.5-9.5 and 17.5-26.3 seconds for PT and APTT, 58-260% and 67-163% for VIII:C and IX:C respectively and 185.8-354.4 x 10/1 for platelets. These reference values were applied to 130 other dogs which were presented to the clinic for various treatments or health checks. The results show how haemostatic analysis can be used to resolve delicate interpretation of laboratory results.
