Fecal smears is likely to be utilized in some instances together with different testing to verify for the irregular presence of parasites or micro organism in stool. Parasite eggs and cysts could also be seen, in addition to micro organism like Clostridium and Campylobacter.

Fecal smears do rely drastically on the expertise and talent of the particular person getting ready and analyzing the pattern.
