LOINC Code 81657-9: Salmonella sp spaO gene NAA+probe Ql (Stl)

81657-9 is a LOINC code used to identify Salmonella sp spaO gene 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 Salmonella sp spaO gene. 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 Salmonella sp spaO 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

Salmonella sp spaO gene [Presence] in Stool by NAA with probe detection
Salmonella sp spaO gene
This test targets the Salmonella sp SpaO gene. The SpaO gene is involved in a secretory pathway responsible for the surface presentation of determinants needed for the entry of Salmonella sp into mammalian cells.[http//www.uniprot.org/uniprot/P40699] This term was created for, but is not limited in use to, the submitter's BD MAX Enteric Bacterial test kit, that is a diagnostic test for the direct qualitative detection of enteric bacterial pathogens.
