FIV, FeLV, and FIPV: interpretation and misinterpretation of serological test results.
Serological testing is a common method of diagnosis of felina viral infections, including feline immunodeficiency virus (FIV), feline leukemia virus (FeLV), and feline infectious peritonitis virus (FIPV). Infections with these viruses can be difficult to diagnose by clinical signs alone and are sometimes clinically inapparent for months after initial exposure. Serological testing to confirm a tentative diagnosis or as a screening tool for infection can be invaluable. However, serological tests must be used only with a thorough understanding of the mechanisms and abilities of the tests, and with recognition of their potential inadequacies and misinterpretations. This report summarizes the assays available for FIV, FeLV, and FIPV, and discusses merits and pitfalls associated with each test.
