<p>The outcome of the tropical pathogen chip test on clinical samples previously confirmed by microscopy or RT-PCR. (A) <i>P. falciparum</i>. (B). <i>P. vivax</i>. (C) CHIKV. (D). DENV 3. Histograms show the percentage of samples tested positive for <i>P. falciparum</i> (n = 64), <i>P. vivax</i> (n = 21), CHIKV (n = 27), and DENV 3 (n = 17) by DNA or RNA lab-on-chip. Statistical significance was measured using 2-sided Fisher exact test between the number of samples tested positive or negative for the respective pathogens by the chip on previously laboratory-confirmed samples (by reference methods). ****P<.0001.</p
