  • a CAP-approved PCR.

  • b One of the samples testing negative by CAP-approved PCR was cultured for influenza A virus, and RPM v.1 showed HAdV-4 and influenza A coinfection. The other negative sample was confirmed to have low-titer HAdV-4.

  • c Three samples that were culture positive for influenza A virus could not be detected by quantitative real-time PCR as well, suggesting that the templates were degraded.
