Table 6 Samples with opposite results between MNCP and RIDT were further compared with rRT-PCR results

From: Evaluation of a novel micro/nanofluidic chip platform for the detection of influenza A and B virus in patients with influenza-like illness

Virus No. detected (MNCP/rRT-PCR)a Sensitivity (%) (95% CI) PPVs (%) (95% CI) Overall concordance rate (%) (95% CI) P value (McNemar’s test)
+/+ +/− −/+ −/−
Influenza A 69 5 0 0 100.00 (93.43–100.00) 93.24 (84.27–97.49) 93.24 (84.27–97.49) 0.06

  1. +: positive; −: negative; MNCP: micro/nanofluidic chip platform; rRT-PCR: real-time reverse transcription polymerase chain reaction; CI: confidence interval; PPVs: positive predictive values
  2. aOf 266 samples, 74 and 42 samples had opposite results between MNCP and RIDT for influenza A and B virus detection, respectively
