How is feline panleukopenia virus diagnosed?

A definitive diagnosis is made based on a positive fecal ELISA test. Feline panleukopenia is suspected when exposure history is correlated with very low white blood cells and possibly low red blood cells (anemia). Fecal testing for feline panleukopenia virus can be performed but is often falsely positive if the cat received a panleukopenia vaccine 5-12 days prior to testing.
