Feline Infectious Peritonitis

Return to the Clinical Trials Homepage

Who Qualifies?

Any cat who is suspected to have FIP by their veterinarian, and does not have a diagnosis of another disease that could be causing similar clinical signs (ex: cancer, heart failure, etc.).

Purpose of the Study

Despite over 50 years of study, a definitive non-invasive diagnostic test for feline infectious peritonitis (FIP) remains elusive. This study will evaluate two new diagnostic strategies – multiplex fluorescent immunocytochemistry and proteomic biomarkers – with the goal of developing a reliable test for this disease.

What is Required?

  • An appointment through CSU emergency and critical care (ECC) or the internal medicine service.
  • Standard blood draw (venipuncture) and routine fluid or solid organ testing (fine needle aspirate), both of which would likely be recommended for diagnostic purposes in any suspected FIP case.


An appointment through internal medicine is free for cats in this study. Several important routine diagnostic tests (complete blood count, biochemistry profile, FIV/FeLV testing, fluid analysis and/or cytology) are paid for by the study.

How to enroll

Please contact Dr. Ben Curtis or Dr. Kelly Santangelo, or call and make an appointment with Community Practice (970) 297-5000 and mention the FIP study.
