Evaluation of three influenza A and B rapid antigen detection kits--update.

Abstract

The report “Evaluation of Three Influenza A and B Rapid Antigen Detection Kits” (1) describes the performance characteristics of BD Directigen Flu A+B, Directigen EZ Flu A+B, and NOW Flu A NOW Flu B. After the completion of this study, the manufacturer modified the Directigen EZ Flu A+B kit and therefore the immunoassay, as described in this paper, will not be available for diagnostic use.
