Biomarker Reference · Parasites
Parasites (Ova, Cysts, Trophozoites) (Parasites) is a clinical biomarker used in microbiome-gut assessment. Intestinal parasites — protozoa (Giardia lamblia, Entamoeba histolytica, Cryptosporidium, Blastocystis hominis, Dientamoeba fragilis) and helminths (roundworms, tapeworms, flukes) — are acquired through contaminated food, water, or contact. It is measured in 2 laboratory tests on BiomarkersLabs.com.
Intestinal parasites — protozoa (Giardia lamblia, Entamoeba histolytica, Cryptosporidium, Blastocystis hominis, Dientamoeba fragilis) and helminths (roundworms, tapeworms, flukes) — are acquired through contaminated food, water, or contact. Concentrated wet-mount microscopy, trichrome staining, and antigen or molecular detection methods improve sensitivity over single routine ova-and-parasite examination.
Detection of pathogenic protozoa or helminths explains persistent diarrhoea, abdominal pain, malabsorption, and eosinophilia. Giardia and Cryptosporidium are common in travellers and those with waterborne exposure; Blastocystis and Dientamoeba are more controversial but are treated when symptomatic. Antigen or PCR methods are more sensitive than microscopy alone for many species.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
