A stress leukogram is characterized by neutrophilia, lymphopenia, and eosinopenia.
A stress leukogram may be caused by either endogenous release of corticosteroids due to stress (like taking a big test), hyperadrenocorticism (Cushing’s disease) or exogenous medication with corticosteroids.
Effects on total WBC vary – expect leukocytosis in dogs, variable effects in cows. Monocyte effects also vary.
Do not confuse this with a physiologic response associated with epinephrine/norepinephrine release. Seen in excited animals – neutrophilia, lymphocytosis, eosinophilia, basophilia. Esp. common in young animals, horses, cats; subsides within about 30 minutes.
