LOINC Code 94316-7: SARS-CoV-2 (COVID-19) N gene NAA+probe Ql (Specimen)

94316-7 is a LOINC code used to identify SARS-CoV-2 (COVID-19) N gene NAA+probe Ql (Specimen) in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. 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 XXX.

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 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: 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 Specimen 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 various specimens, including lower & upper respiratory, serum, stool or urine, by nucleic acid amplification with probe-based detection. Various assays have been developed that contain primer-probe sets targeting N gene. [https//www.who.int/emergencies/diseases/novel-coronavirus-2019/technical-guidance/laboratory-guidance] If using the Centers for Disease Control and Prevention (CDC) SARS-CoV-2 (2019-nCoV) assay, use the codes specific for the target 1 (N1) [LOINC: 94307-6] and target 2 (N2) [LOINC: 94308-4] primer-probe sets for the N gene developed by CDC.[CDC: coronavirus/COVID-19/lab/] The N3 target in the CDC assay is specific for SARS-like Coronavirus [LOINC: 94310-0].
