Question

Is presence of Giardia lamblia in stool is normal??

Answer 1

If a giardia infection is present, the parasite or its cysts can be seen when the stool is looked at under a microscope. ... If giardiasis is suspected, an antigen test may be done on the stool or a sample of the fluid from the small intestine (duodenal contents).If Giardia lamblia is found in the first test (positive result), no more tests are needed. People with chronic giardiasis tend to pass large numbers of the parasite in their stools at about 2-week intervals. ... More parasites seem to be passed in loose stools.
