Giardia Test for Dogs and Cats (antigen)

Further information

Our Giardia Antigen Test for Dogs and Cats provides laboratory screening for Giardia, an intestinal protozoan parasite that can cause gastrointestinal problems in dogs and cats.

Our veterinary laboratory uses targeted antigen testing to check for Giardia in a small faecal sample. This test helps identify infection without the need for routine worming or unnecessary treatment.

When Should You Test for Giardia?

Giardia can affect dogs and cats of any age. However, puppies, kittens and animals living in multi-pet households may have increased exposure.

Common signs associated with Giardia include:

  • Persistent or recurring diarrhoea.
  • Soft or watery stools.
  • Mucus in the faeces.
  • Weight loss or poor weight gain.
  • Occasional vomiting or abdominal discomfort.

Some infected animals show no obvious symptoms. Testing can therefore be useful when investigating gastrointestinal problems or possible exposure.

Giardia Testing After Treatment

We recommend waiting at least three weeks after completing treatment before using our Giardia antigen test for follow-up screening.

If earlier testing is required, our Giardia qPCR test may be suitable from 48 hours after treatment. Please contact our laboratory for guidance if you are unsure which test to select.

Professional Laboratory Testing

Simply collect a small faecal sample using the supplied kit and return it to our laboratory using the prepaid tracked postage.

We normally complete Giardia antigen testing on the same working day the sample arrives. We then email your results directly to you.

Every test includes clear instructions and free after-test advice from our laboratory team.

Please note: This test is suitable for dogs and cats only. If your pet has persistent or severe gastrointestinal symptoms, consult your veterinary surgeon.

Our Giardia Antigen Test for Dogs and Cats screens a faecal sample for antigens associated with Giardia infection.

Our laboratory uses a targeted antigen detection method to identify the presence of Giardia. This provides a practical screening option for dogs and cats with suspected exposure or gastrointestinal symptoms.

The test requires a small faecal sample collected at home. Our trained laboratory staff process the sample using established testing procedures and internal quality controls.

This test screens specifically for Giardia. It does not include a general worm count or screening for other gastrointestinal pathogens.

Our laboratory report provides a clear result for Giardia antigen detection in the sample submitted.

Results are reported as:

  • Detected: Giardia antigen was identified in the sample.
  • Not detected: Giardia antigen was not identified above the detectable limits of the test.

We email the laboratory report directly to you, with free after-test advice available if required.

As Giardia shedding can vary, a negative result does not completely exclude infection. Results should be considered alongside your pet’s symptoms and clinical history.

We normally complete Giardia antigen testing on the same working day your sample arrives at our laboratory.

  • Dispatch: Order before 3 pm, Monday to Friday, for free same-working-day dispatch.
  • Return postage: Free tracked 24-hour return postage is included.
  • Laboratory testing: Normally completed on the working day of arrival.
  • Results: Emailed once laboratory testing and quality checks are complete.
  • Weekends: Samples received over the weekend are normally processed on the next working day.
  • Kit validity: Each kit has a minimum use-by date of eight weeks from the order date.

Important: For follow-up Giardia antigen testing, wait at least three weeks after completing treatment.

If earlier testing is required, our Giardia qPCR test may be suitable from 48 hours after treatment.

For urgent testing, please contact our laboratory to arrange a Unique Lab Reference (ULR) and obtain direct sample submission instructions.

Each Giardia Antigen Test kit is suitable for one dog or cat and includes:

  • Recyclable padded return packaging.
  • Free tracked 24-hour return postage.
  • Laboratory request form and clear sample collection instructions.
  • Recyclable sample collection box in a resealable write-on bag.
  • Biodegradable second sealable bag.
  • Biodegradable natural wood sampling spoon.

All laboratory testing, emailed results and free after-test advice are included.
