Elevated neutrophils and monocytes are indicative of an ongoing bacterial infection. Basophil, eosinophil, and lymphocyte levels would typically increase in response to a viral or allergic reaction. Fungal infections and autoimmune reactions may also result in elevated white blood cell levels, but the pattern of neutrophilia and monocytosis is more suggestive of a bacterial infection.
