Projection using PCA of the electrical impedance data obtained with the bare electrode for L. amazonensis and T. Cruzi samples with different concentrations, as follows. Serum A contained negative antibodies, serum B contained anti-Leishmania antibodies, serum C contained anti-T. Cruzi antibodies. The other samples were the buffer, and the so-called synthetic samples made with the buffer to which anti-Leishmania, anti-T. Cruzi and negative antibodies were added. The mixtures were synthetic samples with anti-Leishmania, anti-T. Cruzi antibodies together. Reproduced with permission from Ref. [92]
