What are some of the tests that are used by veterinarians to diagnose FIP?
The diagnosis of FIP should be based on the veterinarian’s clinical observations which include a taking a history of the animal, physical exam, and laboratory findings (including a titer). The diagnosis is seldom made on a single test. Complete blood counts (CBC), titer, total protein, and a good physical examination are recommended. CBC abnormalities include elevated total protein (mainly globulin), increased numbers of total white blood cells and neutrophils, and decreased numbers of lymphocytes. The fluid is characteristic for FIP, being yellowish, sticky or mucinous, high in protein, and containing numerous neutrophils and macrophages. Biopsies of masses in cats with dry FIP show granulomatous inflammation. There is only one way to confirm a diagnosis of FIP: that is to identify the FIPV in biopsies of masses or at necropsy. The most accurate technique to detect virus is by a procedure called “immunohistochemistry” and is performed on biopsy tissues. This test will show the presenc
