LOINC code80351-0
nameEscherichia coli enterotoxigenic ltA+st1a+st1b genes [Presence] in Stool by NAA with non-probe detection
descriptionThis assay detects the presence of one or more of the Escherichia coli enterotoxigenic ltA, st1a and st1b toxins using PCR and melt curve analysis. The assay does not distinguish between the three toxins. This term was created for, but is not limited in use to, BioFire's FilmArray Gastrointestinal panel, which is intended for the detection and identification of nucleic acids from multiple bacteria, viruses, and parasites directly from stool samples from individuals with signs and/or symptoms of gastrointestinal infection.
statusACTIVE

Fully-Specified Name

componentEscherichia coli enterotoxigenic ltA+st1a+st1b genes
propertyPrThr  =  Present or threshold:  The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold.
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemStool  =  Stool = Fecal
scaleOrd  =  Ordinal:  Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive.
methodNon-probe.amp.tar

last change typeMIN  - change to field other than name
change reasonChanged component name to clarify that this assay detects the toxin genes (vs. protein). Changed Method from "Melt.amp.tar" to "Non-probe.amp.tar", which includes other non-probe based detection methods while still distinguishing from probe-based methods.; 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.
