Biomarker Reference · D. fragilis
Dientamoeba fragilis (D. fragilis) is a clinical biomarker used in microbiome-gut assessment. Dientamoeba fragilis is a flagellate protozoan (often misclassified as an amoeba) that inhabits the colon. It is measured in 1 laboratory test on BiomarkersLabs.com.
Dientamoeba fragilis is a flagellate protozoan (often misclassified as an amoeba) that inhabits the colon. It lacks a cyst stage and is thought to be transmitted within helminth eggs. Molecular detection is more sensitive than microscopy, as the trophozoites are fragile and degenerate rapidly in stool.
Dientamoeba is associated with chronic diarrhoea, abdominal pain, and flatulence in some patients, though asymptomatic carriage also occurs. Detection by PCR in symptomatic individuals with no other identified pathogen may warrant a trial of therapy (metronidazole, iodoquinol, or paromomycin).
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
