Is your pet suffering from frequent diarrhea, unexplained weight loss, or visible worms in the stool?A fecal test may be the first and most important step in identifying the root cause of these symptoms.In this article from Daleely Medical, we’ll walk you through everything you need to know about the fecal test for animals—why it matters, when it’s needed, how it’s performed, what it can reveal, and key tips for accurate results.

What Is a Fecal Test for Animals?

A Fecal Test is a laboratory examination of a stool sample from your pet, performed to detect the presence of:

Internal parasites (such as roundworms and tapeworms)
Parasite eggs
Protozoa (such as Giardia and Coccidia)
Signs of infection, inflammation, bleeding, or digestive issues

Why Is a Fecal Test Ordered?

Veterinarians usually request a fecal test in the following cases:

Frequent or chronic diarrhea
Unexplained weight loss
Presence of blood or mucus in the stool
Recurrent vomiting with digestive symptoms
Visible worms or persistent scooting
As part of the annual routine check-up

Which Animals Should Get a Fecal Test?

Dogs (especially puppies)
Cats
Rabbits
Rodents (hamsters, gerbils, etc.)
Birds and reptiles (with specialized methods)

Types of Fecal Tests in Veterinary Medicine

1. Fecal Flotation

The most common test.
Detects parasite eggs by using a special solution that causes them to float and become visible under a microscope.

2. Giardia SNAP Test

A rapid test to detect Giardia protozoa using antibody-based detection.

3. Coccidia Test

Targets Coccidia parasites, especially in puppies and kittens.

4. Routine Fecal Smear

Examines stool consistency, digestion, presence of mucus, blood, or live parasites.

5. PCR Test

Detects parasite or bacterial DNA with high accuracy.
More expensive but offers precise results.

How to Collect a Stool Sample

Always collect a fresh sample (within 12 hours).
Place it in a clean, sealed container (available from your vet).
Avoid mixing with litter, urine, or cleaning materials.

⚠️ Note:
If you have multiple pets, make sure the sample belongs to the suspected animal.

What Can a Fecal Test Reveal?

Finding	Explanation
Roundworm or tapeworm eggs	Internal parasite infection requiring deworming
Giardia or Coccidia protozoa	Intestinal parasites causing chronic diarrhea
Blood or mucus in the sample	Inflammation or internal bleeding
Pathogenic bacteria (e.g., Salmonella)	Infectious agents needing antibiotics
Undigested food particles	Malabsorption or digestive enzyme issues

What Happens After the Test?

✅ If the result is positive:

Your vet will determine:
- The type of parasite or infection
- The appropriate treatment plan
- Whether isolation is needed to prevent transmission

❌ If the result is negative, but symptoms persist:

Your vet may recommend:
- Repeating the test
- Additional diagnostics like blood tests or imaging
