Table 3. Comparison of ID NOW results with mean Ct value of RT-PCR test.

Ct: cycle threshold; RT-PCR: reverse transcription polymerase chain reaction

Ct Value of Target Genes	Mean Ct Value ORF1 ab gene		Mean Ct Value N gene	Number of RT PCR tests positive	Number of  ID NOW positives
11-20	16.6	15.38		17	17
21-30	24.30	25.78		26	26
>31	34.36	34.52		11	4
