    Snippet: To validate the assay, we first evaluated two synthetic RNAs (see Methods) whose sequences matched the viral sequences of patients from Wuhan, China and Melbourne, Australia (Supp. Fig. 1 ). The first control (MT007544.1) was used to test the analytical sensitivity via the limit of detection (LoD), titrated from 1 million molecules of virus (10 6 ) down to a single copy, using serial log-10 dilutions. The reaction output was measured at 0-, 20-, .....
    Document: To validate the assay, we first evaluated two synthetic RNAs (see Methods) whose sequences matched the viral sequences of patients from Wuhan, China and Melbourne, Australia (Supp. Fig. 1 ). The first control (MT007544.1) was used to test the analytical sensitivity via the limit of detection (LoD), titrated from 1 million molecules of virus (10 6 ) down to a single copy, using serial log-10 dilutions. The reaction output was measured at 0-, 20-, and 30-minute intervals (Figure 1c, Supp. Figure 2a) before the samples were heated to 95 o C for inactivation. The LoD was found to be between 10-100 viral total copies, and this was then replicated to show a similar LoD of 10-100 viral copies on the second synthetic control from the patient from Wuhan (Supp. Figure 2b) .
