Comparison of SensPERT® Leishmania rapid test with two other immunochromatographic tests for the diagnosis of canine visceral leishmaniasis in Brazil

Abstract

Background and Aim: In urban environments, dogs serve as the primary reservoir for visceral leishmaniasis (VL). Rapidly diagnosing canine VL through tests enables early treatment and a favorable prognosis. This study aimed to assess the diagnostic performance of the SensPERT® Leishmania test kit (Dechra®), Alere® Leishmaniasis Ac test kit, and the rapid test dual path platform (TR-DPP®) Bio-Manguinhos in detecting VL. Materials and Methods: 30 serum samples from reactive VL dogs and 30 serum samples from healthy dogs were employed for assessing the sensitivity and specificity variation between SensPERT® Leishmania test kit, Alere® Leishmaniasis Ac test kit, and rapid test dual platform – TR-DPP®. Results: The SensPERT® Leishmania test outperformed Alere® and TR-DPP® in terms of sensitivity, specificity, positive and negative predictive values and demonstrated near-perfect concordance with Alere® and substantial concurrence with TR-DPP®. Conclusion: The SensPERT® Leishmania rapid test proved to be a promising test in the detection of VL in dogs. Keywords: immunochromatography, Leishmania infantum, reservoir.
