ELISA Versus Microscopy

Controlling Giardiasis outbreaks can be accomplished by early diagnosis. Recentally, ELISA has been considered as cost effective diagnostic method which can detect small quantities of coproantigens of parasite, even in mild infections, and diagnosed even if the live parasite is absent in the fecal samples. It can detect different soluble antigens dispersed in fecal matter rather than detecting cysts, trophozoites, or antigens on the surfaces of these morphologic forms.
