Serological methods such as indirect immunofluorescence antibody test (IFAT) and enzyme-linked immunosorbent assay (ELISA) are therefore widely used.

Taking IFAT as the reference, ELISA showed 50% sensitivity, 100% specificity, and 87.14% diagnostic accuracy, with moderate agreement between tests (\u03ba = 0.598). No statistically significant differences were found in hematological parameters between seropositive and non-dual-seropositive dogs (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      values ranged from 0.065 to 0.343).
