EVALUATION OF PRIMARY AND SECONDARY HEMOSTASIS TESTS IN HEALTHY DOGS

摘要

The lack of reference data concerning primary and secondary hemostasis in dogs enforces the necessity of research in this domain. Thus, we explored the parameters indicating the process of hemostasis in dogs of different age sex and breed. Methods of investigating hemostasis were those common in both human and veterinary practice and consisted of separate tests for primary and secondary hemostasis. The tested parameters for primary hemostasis consisted of basic hematological test like bleeding time and number of thrombocites. In secondary hemostasis the tested parameters consisted of clotting time, Howells time and Heparin toleration test. These investigations were carried out in a sample of on 21 dogs of different breeds, with ages between 6 weeks and 10 years.The data obtained from this research pleaded for the usage of average values obtained from testing dogs between 2 and 5 years (for primary hemostasis, bleeding time average value of 4.110.74, the average number of thrombocites being 340 118.51;for secondary hemostasis, clotting time average value of 6.301.26 min., HT average values being 2.270.47 min. HTT average value of 1.160.37 min.) as reference pointes for interpretation of future investigations. And urges the further research in this still not fully investigated domain.
