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.

Term Description

Magnetic beads and fluorescent probes are used to capture and detect targeted nucleic acid sequences specific to Citrobacter species within the ompA and mrkC genes in positive blood culture. The ompA gene encodes "outer membrane protein A" and the mrkC gene encodes "type 3 fimbriae usher".

LP185691-5   Citrobacter sp (ompA+mrkC) genes
Citrobacter is a genus of Gram-negative bacteria in the Enterobacteriaceae family and commonly found in soil, water and wastewater. They can also be found in the human intestine. They are rarely the source of illnesses, except for infections of the urinary tract, infant meningitis and sepsis. C. freundii strains have inducible ampC genes encoding resistance to ampicillin and first-generation cephalosporins. In addition, isolates of Citrobacter may be resistant to many other antibiotics as a result of resistance genes.

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.
