Comparison of the Binax NOW Flu A enzyme immunochromatographic assay and R-Mix shell vial culture for the 2003-2004 influenza season.
The Binax NOW Flu A enzyme immunochromatographic assay was compared to viral culture with R-Mix shell vials for 455 nasal-wash or nasal-aspirate specimens. The overall sensitivity, specificity, positive predictive value, and negative predictive value of the assay were 64.9%, 98.4%, 89.3%, and 93.2%, respectively. However, the assay sensitivity decreased significantly with increasing patient age.
