Fig. 2.

Comparison of the work flow in adaptive testing and non-adaptive testing. In the adaptive setting in Figure (a), two of the time-expensive PCR steps (in red) are required. Furthermore, the interplay of data interpretation after the first PCR and the sample storage management introduces another possible bottleneck. In the non-adaptive case, shown in Figure (b), the work flow is completely linear. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
