Canine Toxocara and Isospora

What we do

The Parasitology Laboratory is a full-service parasite diagnostic laboratory
capable of diagnosing infections in domestic pets and production animals as well as
many zoo, exotic, and wild animals. Our service provides accurate, timely, and
cost-efficient testing in an AAVLD accredited laboratory. The accurate identification
of parasites benefits animals, owners, producers, and veterinarians by helping to
support animal health and well-being, protect our food chain, and support the One
Health missions.


Services provided by the Parasitology Section include detection and identification of
domestic and wild animal parasites from animal feces, tissues, and fluids.

Tests conducted to identify parasite ova or larvae include:

  • Qualitative and quantitative centrifugation concentration flotation techniques
  • IFA (Immunofluorescence) tests for Giardia and Cryptosporidium
  • Direct fecal smears (wet mounts)
  • Baermann technique for recovery of nematode larvae
  • Fluke Sedimentation
  • Tissue digestions to detect Trichinella spiralis larvae


Research and development is part of the mission of the University of Minnesota
Veterinary Diagnostic Laboratory. The Parasitology Section is available for
collaboration and consultation on projects. For further information or to discuss
your needs, please contact [email protected]. We look forward to working with you.

Testing days and turnaround times

Samples must be received at least 1 business day before the scheduled testing day. New client accounts can take up to 2-3 business days to establish before testing can begin. Samples may not always be tested on the first scheduled day after they arrive; however, it is our goal to complete testing within the posted turnaround time. If rush testing is desired, or you plan to send a large amount of samples for testing (for Baermann sedimentation >7, all other procedures >10), please contact us prior to shipping the samples.
