The orange lines represent the DART data for each individual, the dark blue lines represent the viral RNA target N1, and the light blue lines represents the viral target N2. The ratio $p = P/N$ is the proportion of infected in the general population. If a diagnostic test correctly identified 100% of all positive results, it would be as sensitive as possible. The following test parameters for the Accula will be calculated using the ID NOW as a comparator: sensitivity, specificity, positive-predictive value, negative predictive value. Rapid influenza diagnostic tests (RIDTs) detect influenza viral antigens in respiratory tract specimens. Specificity is calculated based on how many people do not have the disease. Antigen tests detect specific viral proteins (antigens) present in a patient sample taken using nasal or nasopharyngeal swabs and can provide results in under a half hour. When also patients that were graded as high suspicion but never tested positive were included in the denominator, the sensitivity (95% CI) was: 67.5% (62.9-71.9%) inpatients; 34.9% (31.4-38.5%) outpatients; 47.3% (44.4-50.3%) all. 0Q0QQ(\&X Test results and respective RT-PCR.
