title: Determination of haematological reference intervals in healthy adult greyhounds.
abstract: OBJECTIVE
  The purpose of this study was to establish breed-specific reference intervals for haematological measurands in non-racing greyhounds. Suitability of the data for partitioning according to sex was also examined.
  
  
  METHODS
  Haematological data were collected from 304 healthy non-racing greyhounds and analysed using non-parametric methods. Results were compared with non-breed-specific canine reference intervals and also with greyhound reference intervals obtained by other investigators.
  
  
  RESULTS
  Compared with non-breed-specific reference intervals, the results showed comparable mean and upper limit and higher lower limit for erythrocyte count; higher values for haemoglobin, haematocrit and mean corpuscular volume; and lower values for total leucocyte count and absolute concentration of neutrophils, lymphocytes, monocytes, eosinophils and platelets. Partitioning according to sex was recommended by the statistical analysis for all analytes except haematocrit and total leucocyte count.
  
  
  CONCLUSIONS
  In this study the reference intervals were derived from a large sample size. The results are in general agreement with previous reports, although higher values for low reference limits have been noted for the erythroid parameters, and lower values for upper reference limits have been observed for the total and different leucocyte counts. Breed-specific reference intervals provide a useful clinical tool for haematological evaluations.
