Escherichia coli shiga-like toxin [Presence] in Stool by Immunoassay   21262-1

LOINC Code


LOINC code21262-1
nameEscherichia coli shiga-like toxin [Presence] in Stool by Immunoassay
descriptionThis assay detects clinically significant shiga-like toxins, including Stx1a and Stx2a, in stool by immunoassay methods.
statusACTIVE

Fully-Specified Name

componentEscherichia coli shiga-like toxin
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.
methodIA  =  Immunoassay:  Encompasses all immunoassays with a few exceptions, including Immune Blot and Immune Fluorescence, which were created based on historic usage.

change reasonThe 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.; The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.; Changed Component name from "Escherichia coli shiga-like" to "Escherichia coli shiga-like toxin" to align with current naming of E coli shiga-like toxins.
