What does pooled testing mean?

To save supplies, especially in situations where resources are limited, and test more people, pooled testing may be implemented. Pooled testing means taking samples from multiple people, storing part of each sample individually, and combining the other part of each sample into batches, or pools, and then testing each pool. This allows many more people to be tested in an initial round of testing than tests that do not use pools, and then for any pool that indicates a positive result, the samples that contributed to that pool can be tested individually to identify the positive people.
