Blood biochemistry and hematology: breed considerations

ffelis

Introduction

  • A reference interval (RI) is a key component of the laboratory report informing the clinician as to the health status of their patient. Values within the RI are less likely to be associated with pathology.
  • The RI may also be affected by factors such as patient age, species and the type of sample obtained (eg potassium, total protein and globulins, will differ between plasma and serum).
  • The RI is instrumentation and reagent dependent. This explains the differences in RI for different diagnostic laboratories.
  • Determining a reference population is not straightforward as some breeds of cats and dogs consistently have values outside of the standard RI absent a pathologic reason.
  • An awareness of breed variations in both biochemistry and hematology parameters can facilitate interpretation of these results.
