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 Escherichia coli Stx2 toxin stx2 gene. It is commonly used with the system or sample type Stool.

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.

Key facts

  • Escherichia coli Stx2 toxin stx2 gene [Presence] in Stool by NAA with probe detection
  • Escherichia coli Stx2 toxin stx2 gene
  • This term was created for, but is not limited in use to, Nanosphere's Verigene Enteric Pathogens Nucleic Acid Test, which is intended for the detection and identification of common pathogenic enteric bacteria, viruses, and genetic virulence markers in stool specimens from individuals with signs and symptoms of gastrointestinal infection.
