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 RNA. It is commonly used with the system or sample type BAL.

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: Observation
  • Method: Probe.amp.tar

What it does not mean

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