To evaluate SARS-CoV-2 genome detection using pooled samples by RT-qPCR assay, compared to individual samples. At first all samples were tested individually using two commercial methods targeting ,  and  genes. Then, four experimental groups of samples were pooled and evaluated using the same detection methods. Compared to the individual sample testing, the sample pooling conserved the sensitivity of the detection in all groups of pooled samples when the Ct value in single test was lower than 33. Specimen pooling may fail to detect positive samples with high Ct values. However, in scarcity of reagents or in population surveys, it could be considered as an alternative method in low prevalence settings.
