Pooled testing can be one good option if schools decide to do routing surveillance testing. The benefits are that the tests can be batched and run together, decreasing time to getting The Results and potentially decreasing cost of testing, the major drawback is that pooled testing is best used in low prevalence settings, because if there is a positive pool then all of the individual samples in that' batch' have to be disaggregated and tested individually to identify the actual positive sample or samples.
