LOINC 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.;
