LOINC Code 80679-4: E. coli stx1+stx2 genes NAA+probe Ql (Stl)

80679-4 is a LOINC code used to identify E. coli stx1+stx2 genes NAA+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 Stx1+Stx2 toxin stx1+stx2 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 Stx1+Stx2 toxin stx1+stx2 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: Both
  • Method: Probe.amp.tar

What it does not mean

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

Key facts

  • Escherichia coli Stx1 and Stx2 toxin stx1+stx2 genes [Presence] in Stool by NAA with probe detection
  • Escherichia coli Stx1+Stx2 toxin stx1+stx2 genes
  • Qualitative detection of nucleic acid sequences in Escherichia coli shiga-like toxin 1 and 2 (stx1/stx2) genes in stool specimens by PCR-based methods. This assay does not differentiate between the two toxin genes. This term was created for, but not limited in use to, the xTAG® Gastrointestinal Pathogen Panel (GPP).
