Term Description

This code describes molecular detection of Entamoeba histolytica/dispar complex (E. histolytica, E. dispar, E. nuttalli, and E ecuadoriensis) DNA by RT-PCR. It targets a sequence of the DNA coding for the 15S ribosomal RNA that is common to these four species. So a positive result indicates whether any one of these species is present without specifying which one. In the submitter's laboratory, it is used only on human specimens, mostly stool but pus and tissue as well. E. dispar is a commensal in the human digestive tract, and E. histolytica is the only one thought to be pathogenic in humans. The other two species are found in animals and not thought to inhabit the human gut. A positive can be followed up in the submitter's lab by specific identification of the species using DNA sequencing (see LOINC 70294-4).

Additional species that have been found in the gut include Entamoeba moshkovskii, Entamoeba poleki, Entamoeba coli, and Entamoeba hartmanni. E. histolytica, E. dispar, and E.moshkovskii are morphologically identical but are different biochemically and genetically.

Entamoeba histolytica and Entamoeba dispar are a complex of two different but morphologically identical species. E. dispar is non-invasive commensal in the intestine of humans. E. histolytica is an invasive species assoicated with cell and tissue damage. Source: Regenstrief LOINC

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.
