MNCP: micro/nanofluidic chip platform; RIDT: rapid influenza diagnostic test; rRT-PCR: real-time reverse transcription PCR
^aRIDT, MNCP, and rRT-PCR test was conducted successively in 255 of 266 patients for influenza A virus detection (11 patients were excluded because of sample volume shortage), and in 259 of 266 patients for influenza B virus detection (seven excluded because of sample volume shortage)
