Evaluación de una prueba rápida para el diagnóstico de la infección por Trypanosoma cruzi en suero

we tested a rapid diagnostic test (rdt) to detect trypanosoma cruzi infection using a total of 284 human sera, some of them from provedcases ofchagas disease (n = 145) and healthy individuals from non-endemic areas (n = 139). another group included was non chagasic serum samples of individuals of other parasitic and non parasitic disease (n = 56), all of them with known serological test results. the rdt had a specificity of 99,3% and a sensitivity of 99,3%. the agreement with elisa and ifat was 98,2%. according to the results and the feasibility of the rdt should be an ideal tool for screening purposes in disease surveillance and intervention programs ofchagas disease.
