The Clinical Veterinary Parasitology Diagnostic Laboratory provides services to the hospital's veterinarians, as well as the veterinarians of Ohio, and the United States. We also support the research community of OSU and other public and private entities involved in animal health. Testing for research can be tailored to meet specific study needs.  We do not accept samples unless the samples are submitted through your veterinarian/animal health professional or you are a current VMC client with your animal examined by a VMC veterinarian.

Accurate result reporting with a rapid turnaround time is important to our laboratory and for quality patient care.  Highly qualified and trained professional staff provides essential, state-of-the-art diagnostic testing and access to board-certified Internal Medicine Specialists in Small, Large or Equine Medicine and Veterinary Dermatology to complement our diagnostic services.  Our primary technician has over 20 years of experience in parasite diagnostics.

Our Parasitology laboratory utilizes superior diagnostic techniques to recover and identify parasites inhabiting a wide variety of pets, livestock, wildlife and zoological hosts. We employ the double centrifugal flotation procedure to recover parasite ova/cysts/oocysts to maximize yield and ensure accuracy of fecal parasite identification. They also participate in the Veterinary Laboratory Association Quality Assurance Program in parasitology.
