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-related coronavirus N gene. It is commonly used with the system or sample type XXX.

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.CDC primer-probe set N3

What it does not mean

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

Key facts

SARS-related coronavirus N gene [Cycle Threshold #] in Specimen by Nucleic acid amplification using CDC primer-probe set N3
SARS-related coronavirus N gene
The quantitative cycle threshold value for the detection of nucleic acids within the N gene of the SARS-related Coronavirus (SARSr-CoV) in various specimens, including lower & upper respiratory, serum, stool or urine, by PCR with probe-based detection. This term was created for, but not limited in use to, the N3 primer-probe set used in the COVID-19 assay developed by the Centers for Disease Control and Prevention (CDC).[CDCcoronavirus/COVID-19/lab/]
