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 Bacterial cephalosporin resistance (bla(CTX-M)) 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 Cephalosporin resistance (bla(CTX-M)) gene [Presence] by Nucleic acid capture and probe detection in Positive blood culture
Bacterial cephalosporin resistance (bla(CTX-M)) gene
Resistance marker gene results will only be reported when an organism is also detected by the assay (includes any Acinetobacter, Citrobacter, Enterobacter, Proteus, E. coli, K. pneumoniae, K. oxytoca, and/or P. aeruginosa). Resistance marker not detected result for any of the antimicrobial resistance markers does not indicate susceptibility, as resistance may occur by other mechanisms. Sub-culturing and antimicrobial susceptibility testing (AST) testing is required in order to assign a resistant and/or susceptible phenotype to each isolate recovered from the blood culture sample. antibiotic resistance gene markersC
