In herpetology, hematological parameters are widely used in veterinary practice, in environmental and biological studies and as a complex bioindicator. Discrepancies in the interpretation of the results of different studies are due to the characteristics of reptile hematopoiesis and variability in the morphology of leukocytes, which leads to distortions of the real picture. The purpose of the work is to summarize the critically significant multivariate aspects in reptile hematology that are of significant importance for theory and practice.
