Respiratory NAAT panel: specimen to target result

Read first

Molecular panels answer whether specific targets were detected in that specimen. They do not grade disease severity or replace specimen quality review.

SpecimenNasopharyngeal, nasal, or respiratory source

Start with source and collection quality. The result belongs to the submitted specimen and the assay targets on the panel.

Target detectedAmplification crosses threshold

Detected means a target signal was found by that assay. Report wording follows the platform and laboratory SOP.

Not detectedNo target signal above cutoff

Not detected means no listed target was detected by that method. It does not prove absence of every respiratory virus.

Key takeaways
  • Molecular panels detect targets included on the panel.
  • Controls and specimen quality come before interpretation.
  • Negative means not detected by that assay, not every virus excluded.
Remember

NAAT reads targets in a specimen. Keep the wording that precise.
