Comment
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.
Map-To Long Common Name Mapping Guidance
88258-9 Escherichia coli oppA gene [Presence] by Probe in Positive blood culture

Term Description

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".

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.
