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 S gene codon N501Y. 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: Both
  • Method: Molgen

What it does not mean

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

Key facts

SARS-CoV-2 (COVID-19) S gene codon N501Y [Presence] in Specimen by Molecular genetics method
SARS coronavirus 2 S gene codon N501Y
This term is used to report whether the spike protein N501Y codon change (currently a mutation compared to the original strain) was detected in the SARS coronavirus 2 (SARS-CoV-2) strain by molecular methods. To report whether the N501 codon (currently the wild type) was detected, use [LOINC96756-2]. For using a single code to report any mutation found in the S gene, use [LOINC: 96751-3]. To report the SARS-CoV-2 variant strain identified based on the sequencing study, use SARS-CoV-2 (COVID-19) variant [Type] in Specimen [LOINC: 96741-4].
