RESUMO
BACKGROUND: The Mindray BC-5000Vet hematology analyzer is a flow cytometry-based automated hematology analyzer that generates a complete blood count with a five-part white blood cell (WBC) differential count. OBJECTIVES: We aimed to validate reliability results of the Mindray BC-5000Vet for use in dog and cat blood. METHODS: Imprecision was performed using the manufacturer's quality control material at low, normal, and high levels. Blood sample results of healthy and ill dogs and cats were studied for comparability between manual methods and the Mindray BC-5000Vet analyzer. Forty dogs and 40 cats were included in the study. RESULTS: Precision for red blood cell (RBC) parameters was excellent, with a coefficient of variation within-run (%CVw ) and between-run (%CVb ) of <2%. WBC count and differential count showed %CVw and %CVb <8%; however, %CVw and %CVb of low-level control material gave >9% eosinophils. The correlation between the BC-5000 Vet and manual methods in normal and abnormal canine and feline blood samples showed excellent correlations for the RBC counts, hemoglobin concentrations, hematocrits, and WBC counts (r > .93). The differential WBC analysis of canine blood showed good correlation (r = .80-.92). Feline blood samples showed excellent correlations for neutrophils and lymphocytes, with a good correlation for monocytes and eosinophils. CONCLUSIONS: The Mindray BC-5000Vet hematology analyzer proved a suitable instrument for routine analysis in dogs and cats with various hematologic abnormalities.
