Characteristic changes in blood parameters associated with delayed analysis of equine blood samples using a common hematology analyzer (Advia 120, Bayer Corporation, Tarrytown, NY) include increased numbers of normocytic, hypochromic red blood cells ( RBCs), increased numbers of macrocytic, hypochromic RBCs, misclassification of granulocytes as mononuclear cells using the basophil reagent method, and a pseudothrombocytosis due to the categorization of lyzed erythrocytes as platelets. It is not uncommon in equine medicine for delays in sample analysis up to 24 hours to occur as a result of restricted access to diagnostic laboratories. Ideally, analysis of the sample should occur promptly to prevent the formation of cellular changes such as swelling and degeneration, which can affect both blood smear analysis and the evaluation of the blood sample with an automated hematology analyzer.

A single CBC is merely a “snapshot” in time therefore, serial CBCs are often beneficial in better understanding a progressing or improving disease process.īlood submitted for a CBC should be collected and immediately mixed with EDTA, which is the preferred anticoagulant for mammalian blood. Insight into disease processes, their severity, and even diagnoses can be gleaned from a complete evaluation of the CBC, especially in conjunction with a peripheral blood film. The complete blood count ( CBC) provides information beyond the concentrations of blood cells.
