    nNO is effective for diagnosing PCD with 98% sensitivity.

  • 2

    Must be used with other diagnostic methods, not standalone.

  • 3

    Cutoff for children aged 5+ is 77 nL/min.

  • 4

    Respiratory infections can significantly lower nNO values.

  • 5

    Variability in nNO performance across genetic subtypes.

  • 6

    Technical factors affect test performance.

  • 7

    Electrochemical devices are more accessible alternatives.
