75682-5Deprecated Cephalosporin resistance (bla(CTX-M)) gene [Presence] by Nucleic acid capture and probe detection in Positive blood cultureDeprecated

Status Information

The "Probe.mag capture" Method has been deprecated and replaced with the more general "Probe" Method since the "mag capture" portion represents how the nucleic acids are isolated, which is not a distinction made in the LOINC Method for molecular tests. Given that updating the Method would change the meaning of the term, a new term was created to replace the existing term as recommended by the Special Topics workgroup on PCR-based Methods and approved by the LOINC Lab Committee at the June 2017 meeting.

88250-6 Cephalosporin resistance blaCTX-M gene [Presence] by Molecular method

Term Description

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 markers: C

Basic Attributes

First Released
Version 2.50
Last Updated
Version 2.63
Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
