Evaluation of sample pooling for diagnosis of COVID-19 by real time-PCR: A resource-saving combat strategy.

Pooled-sample PCR analysis strategies can save substantial resources and time for COVID-19 mass testing in comparison with individual testing without compromising the resulting outcome of the test. In particular, the pooled-sample approach can facilitate mass screening in the early coming stages of COVID-19 outbreaks, especially in low- and middle-income settings, and control the spread by meticulous testing of all risk groups.
