Discussion/Interpretation
CBC reveals a marked lymphocytosis with a slight mature neutrophilia. Causes of lymphocytosis include chronic infection or inflammation, lymphocytic leukemia, and physiologic lymphocytosis. Examination of the blood film reveals numerous small lymphocytes. Lymphoblasts or atypical lymphocytes were not observed. Tests for FeLV and FIV were negative.
This is an example of a physiologic lymphocytosis and neutrophilia in a young, healthy, scared cat. Epinephrine release causes demargination of neutrophils and lymphocytosis. Both changes are transient and values return to normal within 1-2 hours.
