Design outcomes

Primary

MeasureTime frame
Evaluate the correlation of the 2 diagnostic methods through the ROC analysis and determination of the correlation coefficient (r).;Evaluate the sensitivity of the new method (BAT) in comparison to the gold standard (PCR).;Evaluate the specificity of the new method (BAT) in comparison with the gold standard (PCR).

Secondary

MeasureTime frame
Assess the sensitivity of the new method (BAT) in comparison with the gold standard (PCR) in subgroups of patients: symptomatic only, only asymptomatic, by age group, by sex, according to the PCR's ct ranges.;Assess the specificity of the new method (BAT) in comparison with the gold standard (PCR) in subgroups of patients: symptomatic only, only asymptomatic, by age group, by sex, according to the PCR's ct ranges.;Perform exploratory analysis of results found in the new method (BAT) if there is identification of other respiratory viruses.
