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 Campylobacter coli+jejuni tuf 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

  • Campylobacter coli+jejuni tuf gene [Presence] in Stool by NAA with probe detection
  • Campylobacter coli+jejuni tuf gene
  • This test targets the tuf gene that is common to two species in the Campylobacter group, coli and jejuni, and does not distinguish between them. The tuf gene encodes elongation factor Tu. This term was created for, but is not limited in use to, the submitter's BD MAX Enteric Bacterial test kit, which is a diagnostic test for the direct qualitative detection of enteric bacterial pathogens.
