LOINC Code 75678-3: E. coli oppA gene Nucleic acid capture and probe detection Ql (Pos bld culture)

75678-3 is a LOINC code used to identify E. coli oppA gene Nucleic acid capture and probe detection Ql (Pos bld culture) 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 (oppA) gene. It is commonly used with the system or sample type Bld.pos growth.

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 (oppA) gene. It is commonly used with the system or sample type Bld.pos growth.

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: DEPRECATED
  • Order vs observation: Observation
  • Method: Probe.mag capture

What it does not mean

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

Key facts

  • Deprecated Escherichia coli (oppA) gene [Presence] by Nucleic acid capture and probe detection in Positive blood culture
  • Escherichia coli (oppA) gene
  • Magnetic beads and fluorescent probes are used to capture and detect targeted nucleic acid sequences specific to Escherichia coli species within the oppA gene in positive blood culture. The oppA gene encodes "oligopeptide ABC transporter periplasmic binding protein", an ATP-dependent oligopeptide transporter that is a member of the ATP-Binding Cassette (ABC) Superfamily of transporters. This term is based on, but not limited in use to Nanosphere's Verigene Gram-Negative Blood Culture test, which reports specimens containing Shigella spp. and/or E. coli as "E. coli Detected".
