The Role of Surveillance Inspections in Reducing False-Positives of SARS-CoV-2 Omicron Variants during the COVID-19 Epidemic

Table 2

Comparison of ORF1 and N gene results between true-positive and false-positive samples.

	The number of true-positivesamples	True-positive results (Ct, mean ± SD)	The number of false-positivesamples	False-positive results (Ct, mean ± SD)	t value	value
ORF1 genes	30	29.11 ± 4.63	80	35.67 ± 3.12	−4.107	<0.001
N genes	30	29.21 ± 4.55	80	34.99 ± 2.96	−3.522	<0.001

ORF1: open reading frame 1, and N: nucleocapsid protein, Ct: cycle threshold, SD: standard deviations.
