Author Correction: A pooled testing strategy for identifying SARS-CoV-2 at low prevalence

The Original Article was published on 21 October 2020

Correction to: Nature https://doi.org/10.1038/s41586-020-2885-5 Published online 21 October 2020

In Fig. 2 of this Article, the Ct values for the orf1ab gene (shown in Fig. 2b) in samples B16121 and B16122 at 20×, 50× and 100× dilution were accidental duplications of those of the N gene (shown in Fig. 2a). The Ct values for orf1ab have been corrected in Fig. 2 of the original Article, and Fig. 1 of this Amendment shows the original and corrected Fig. 2b, for transparency. As B16121 and B16122 are both low-Ct samples, this change has no effect on our conclusion that typical samples are easily detected after 100-fold dilution.

In Extended Data Table 2 of this Article, which presents the source data for Fig. 2, the orf1ab Ct values for sample B16121 were incorrectly given as 29, 29.74 and 30.54 for 20×, 50× and 100× dilution, respectively, instead of 31, 30.51 and 30.95, respectively. In addition, the orf1ab Ct values for sample B16122 were incorrectly given as 26.81, 27.75 and 29.07 for 20×, 50× and 100× dilution, respectively, instead of 28.5, 29.4 and 30.2, respectively. Extended Data Table 2 of the original Article has been corrected online. We thank T. Carey for drawing this error to our attention. The original Article has been corrected online.
