Interpretation
Negative:
Negative results indicate the absence of antibodies to members of the Leishmania donovoni complex. Repeat testing in 2 to 3 weeks if clinically indicated. Immunocompromised patients frequently have low or undetectable antibodies to Leishmania species.
Positive:
Positive results indicate the presence of antibodies to members of the L donovoni complex, the causative agents of visceral leishmaniasis. Results should not be used as the sole criterion for diagnosis or treatment of visceral leishmaniasis and should not be used to diagnose other forms of leishmaniasis. False-positive reactions due to malaria infection have been reported.
