LOINC Code 80351-0: E. coli enterotoxigenic ltA+st1a+st1b genes NAA+non-probe Ql (Stl)

80351-0 is a LOINC code used to identify E. coli enterotoxigenic ltA+st1a+st1b genes NAA+non-probe Ql (Stl) 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 Escherichia coli enterotoxigenic ltA+st1a+st1b genes. It is commonly used with the system or sample type Stool.

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 enterotoxigenic ltA+st1a+st1b genes. 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: Non-probe.amp.tar

What it does not mean

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

Key facts

  • Escherichia coli enterotoxigenic ltA+st1a+st1b genes [Presence] in Stool by NAA with non-probe detection
  • Escherichia coli enterotoxigenic ltA+st1a+st1b genes
  • This assay detects the presence of one or more of the Escherichia coli enterotoxigenic ltA, st1a and st1b toxins using PCR and melt curve analysis. The assay does not distinguish between the three toxins. This term was created for, but is not limited in use to, BioFire's FilmArray Gastrointestinal panel, which is intended for the detection and identification of nucleic acids from multiple bacteria, viruses, and parasites directly from stool samples from individuals with signs and/or symptoms of gastrointestinal infection.
