Chronic disease of any type, including adrenal disease, may cause low-
grade anemia, which is most often non-regenerative.  Slightly elevated
lymphocytes values are commonly seen in middle-aged to older ferrets
chronically infected with Helicobacter, or with a history of ECE
infection.  These two common inflammatory disorders may also cause mild
anemia or chronic disease.
