Influenza A, influenza B, and COVID-19 viral antigens are generally detectable in upper respiratory specimens during the acute phase of infection. Positive results indicate the presence of viral antigens, but clinical correlation with patient history and other diagnostic information is necessary to determine infection status.
Store as packaged in the sealed pouch at room temperature or refrigerated (4-30°C).
1. Sensitivity and Specificity of Flu A
The total sensitivity of Flu A is 100.0%; 95% CI:(97.9% - 100.0%)
Total specificity of Flu A from the above table is 99.4%; 95%Cl: (88.3%-100.0%)
2. Sensitivity and Specificity of Flu B
The Flu A/B Test Cassette (nasopharyngeal Swab Specimen) was compared with a commercial PCR.
The total sensitivity of Flu B is 100.0%; 95% CI:(81.5% - 100.0%)
Total specificity of Flu B from the above table is 99.4%; 95%Cl: (88.3%-100.0%)
Simple Test Procedure: NO laboratories or trained personnel request, easy-to-interpret results.
Complete Testing: One sampling can Detect and differentiate of COVID-19 antigen, Influenza A and B virus.
Better Performance: The sensitivity and specificity for Influenza A or B are both > 99%.
The sensitivity for COVID-19 is 97.3% and the Specificity is 98.4%.
Fast Result: Results in only 15 minutes.
Early diagnosis and early isolation can be achieved for the infection of the two pathogens, to block the transmission of pathogens, and reduce the risk of epidemic transmission. In the period of the COVID-19 pandemic, it can help doctors distinguish between the novel coronavirus infection and influenza virus infection and make a targeted treatment plan.
