Cryptococcus Testing

If you're a veterinarian and your patient has Cryptococcus symptoms, we can test for Cryptococcus at Oregon State University, Veterinary Diagnostics Laboratory (OSU, VDL).

You can participate in this prospective study by sending samples of suspected cases to OSU, VDL for further analysis. Our grant award allows us to assist in offsetting the cost of testing samples at OSU, VDL at no charge to you.

Oregon State University requires:

  1. A routine a swab in transport media (culturettes, not refrigerated), sent by regular mail with the submission form (see below).
  2. Serum sample (red top) for Cryptococcal antigen test.
  3. If diagnosed by cytology, please collect a fresh sample when possible and send to OSU.
  4. If diagnosed from a formalin or paraffin sample, please have the sample forwarded to OSU for PCR testing.
  5. Download the OSU, VDL submission form (pdf) and under the Mycology section on page 2, check "Fungal Culture" or  "Cryptococcal Antigen Detection Panel." The form also needs to mention "Special Cryptococcus Study.”
