When should fecal tests for parasites be indicated in chronic enteropathy?

• A. Never
• B. Only in cats
• C. Only if there is fever
• D. If there is a history of exposure or endemic parasite prevalence or failure to respond to diet, to rule out parasitic infections causing persistent GI signs.

Answer: (D)

In chronic enteropathy, parasites should be considered as a potential cause whenever there is any risk that they could be involved. The key idea is to base fecal testing on practical indicators: when the animal has a history of exposure (outdoor access, hunting, contact with other animals, ingestion of prey or raw meat), when the region has a known prevalence of parasitic infections, and when there is persistent GI disease that does not improve with dietary management. These factors raise the probability that a parasitic infection is contributing to ongoing signs, so testing helps identify and treat a treatable cause rather than assuming non-parasite etiologies. Fecal testing is not limited to one species, not restricted to fever, and not something you should only do in a specific circumstance. Fever is not a reliable criterion for parasites in chronic enteropathy, and several parasites can cause chronic GI signs without fever. Even with a diet trial, if signs persist, parasites remain in the differential and testing is warranted. In practice, using a combination of history, regional risk, and response to diet provides the most sensible trigger for fecal parasite testing.
