Influenza A + B

Rapid immunochromatographic test for the qualitative detection of influenza A and B antigens in nasal swab or throat swab or nasal aspirate specimens. It is intended to aid in the rapid differential diagnosis of influenza A and B viral infections.

Nasal Swab Specimen:

Relative sensitivity: Influenza A 94.7%, Influenza B 81.0%*

Relative specificity: Influenza A 95.4%, Influenza B 98.8%*

Throat Swab Specimen:

Relative sensitivity: Influenza A 69.2%, Influenza B 90.9%*

Relative specificity: Influenza A 94.0%, Influenza B 95.7%*

Accuracy: Influenza A 90.0%, Influenza B 95.0%*

Nasal Aspirate Specimen:

Relative sensitivity: Influenza A 88.1%, Influenza B 96.2%*

Relative specificity: Influenza A 93.0%, Influenza B 97.5%*

Accuracy: Influenza A 91.3% Influenza B 97.1%*

Overall Specimen:

Relative sensitivity: Influenza A 86.8%, Influenza B 91.7%*

Relative specificity: Influenza A 94.0%, Influenza B 97.5%*
