FIG 3.

Microarray diagnostic sensitivity and specificity. A panel of 5 virus groups (rotavirus group A [RV-A], human astrovirus [HAstV], human adenovirus [HAdV], calicivirus [CV], and human enterovirus [HEV]) was tested by RT-PCR in all 76 samples. Results were compared to those obtained by microarray analysis. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the microarray (array), compared to RT-PCR (PCR) for detection of particular pathogens are shown.
