Other laboratory tests may be used in the confirmation of CAV1 infection. Although virus isolation (on tissues or secretions) and immunofluorescence (on infected tissues) are both possible, serology is the most useful adjunctive test. CAV1 antibodies typically increase to levels greater than those post-vaccination during active infection, and so a rising antibody titre can confirm a diagnosis of infectious canine hepatitis.
