What is Microscopic Ova and Parasite Examination?
Microscopic examination identifies intestinal parasites through direct visualisation of ova, cysts, trophozoites, and larvae in concentrated and permanently stained faecal specimens. The technique relies on morphological identification under oil immersion, distinguishing pathogenic protozoa (Giardia lamblia, Entamoeba histolytica, Cryptosporidium species, Cyclospora cayetanensis) and helminths (roundworms, tapeworms, flukes) from non-pathogenic commensals. Multiple specimens increase diagnostic yield because shedding is often intermittent.
