Evaluation of a rapid IgM detection test for diagnosis of acute leptospirosis in dogs.

Recently, a lateral flow assay (LFA) for detection of -specific IgM in canine sera became commercially available in Europe. The present study aims to evaluate the diagnostic performance of this assay using canine sera from a collection of diagnostic accessions. Diagnostic sensitivity was assessed by testing 37 acute-phase and 9 corresponding convalescent-phase sera from dogs with a confirmed diagnosis of leptospirosis.
