URINE AND PARASITE TESTING
Fecal Testing
Stool testing that helps detect intestinal parasites, Giardia and other concerns using methods selected for the animal’s history and risk.
THE SHORT VERSION
Testing helps answer a clinical question.
Fecal testing looks for parasite eggs, larvae, antigens or genetic material, depending on the technique. A veterinarian may combine methods because not every parasite sheds consistently or appears on the same test.
What is this test?
Fecal testing looks for parasite eggs, larvae, antigens or genetic material, depending on the technique. A veterinarian may combine methods because not every parasite sheds consistently or appears on the same test.
What information can it provide?
- Centrifugal flotation concentrates many parasite eggs so they can be examined microscopically.
- Giardia antigen tests may identify infection when cysts are not easy to see.
- Parasite antigen testing can help detect certain infections even when eggs are absent or few.
- Polymerase chain reaction testing identifies targeted genetic material when clinically appropriate.
- Sample freshness, quantity and contamination can change the usefulness of a result.
When might your veterinarian recommend it?
- Screen young animals, investigate diarrhea, weight loss or exposure risk.
- Evaluate travel, boarding, hunting, outdoor access or contact with other animals.
- Monitor preventive care and discuss potential household or human-health concerns.
What can owners do before the visit?
- Ask how much fresh stool the clinic needs and whether refrigeration is appropriate.
- Avoid mixing the sample with litter, soil, grass or cleaning chemicals.
- Bring information about preventives, travel, diet and recent treatments.
What can this test not tell you by itself?
- A negative single test does not rule out every parasite.
- Some organisms shed intermittently, and some infections require antigen or other specialized testing.
- Testing frequency is individualized; guidelines and risk factors inform the discussion.
Do not change medication, interpret an abnormal number as a diagnosis or delay urgent treatment without direction from your veterinary team.
Useful questions for your appointment
- Which testing methods are being used, and why?
- Could intermittent shedding or a recent treatment affect the result?
- Should other animals or household members take precautions?
