Interpretation of L. Hardjo serology (ELISA) results
>45% - Positive
20-45% - Inconclusive
<20% - Negative
Results are measured by Percent Positivity.

Seroconversion occurs after approximately 4 weeks and titres may persist for months to years. Diagnosis of the status of infection at the herd level requires testing of a statistical proportion of the herd. Where only inconclusive results are obtained consideration should be given to increasing the number of animals in the group or herd that are tested, or to collect second samples from the inconclusive animals after 4 weeks to examine for seroconversion.
