What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component SARS coronavirus 2 N gene. It is commonly used with the system or sample type Nose.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Both
  • Method: Probe.amp.tar

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

  • SARS-CoV-2 (COVID-19) N gene [Presence] in Nose by NAA with probe detection
  • SARS coronavirus 2 N gene
  • Qualitative detection of nucleic acids within the nucleoprotein (N) gene of SARS coronavirus 2 (SARS-CoV-2) in nasal specimens by nucleic acid amplification with probe-based detection. Testing is performed for the diagnosis of Coronavirus disease 2019 (COVID-19).
