Part Description

LP66842-3   Escherichia coli shiga-like toxin
Shiga-like toxin is generated by some strains of Escherichia coli, known as Stx-producing E. coli (STEC). Shiga-like toxins are named for their similarity to the AB5-type shiga toxin produced by the bacteria Shigella dysenteriae. There are two primary types, known as Stx1 (also Stx1a or SLT1) and Stx2 (also Stx2a or SLT2). Variants of Stx1 and Stx2 have been identified but they are rarely found in clinical specimens and few are clinically significant. [PMID: 25530917] Shiga-like toxins are associated with hemolytic-uremic syndrome (HUS) in which patients present with thrombocytopenia, hemolytic anemia, and kidney failure.

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.; 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.
