Rapid Chagas diagnosis in clinical settings using a multiparametric assay.


The development of an immunoassay for detecting circulating antibodies against Trypanosoma cruzi with a good performance appears to be crucial in clinical settings for the management of Chagas disease. Here we propose a new automated ELISA test performed on serum samples using 2 different T. cruzi antigens (a recombinant protein and a T. cruzi whole extract) placed in parallel in separate solid phases. This automated diagnostic tool allows the simultaneous analysis of a large number of sera, by determining the presence of antibodies against both antigens by a single run test, with high sensitivity and specificity. The simultaneous analysis of the reactivity against the 2 antigens in a biparametric modality reduces the percentage of false-negative sera and allows a more accurate diagnosis. Using this multiparametric approach, we propose an effective algorithm for the first step of Chagas diagnosis by performing a single test, with time and cost savings.
