This study compared the level of agreement between two commercially available rapid serological tests and the official screening test used to detect Leishmania seropositive dogs in Brazil. Ninety-five canine sera from a visceral leishmaniasis endemic area were tested by using the official immunochromatographic test (T1; rK28 antigen) based on dual path platform technology, a rapid ELISA (T2; purified Leishmania antigens) and an immunochromatographic test (T3; rK28 antigen) based on lateral flow. There was substantial agreement (Kappa 0.77; 95% confidence interval, CI, 0.62–0.91; P < 0.001; observed agreement 90.5%) between T1 and T2, and a fair agreement (Kappa 0.26; 95% CI 0.08–0.43; P < 0.001; observed agreement 74.7%) between T1 and T3. Sixteen dogs positive at T1 and T2 were negative at T3. T2 may be a reliable alternative to T1, while T3 could lead to an underestimation of the actual number of seropositive dogs.
