3 tests that determines if your cat has FIP

Updated: Nov 15, 2023

We have compiled 3 commonly used tests by veterinarians to detect whether your cat has been infected by the feline infectious peritonitis virus (FIPV). There is no single test that can conclusively determine if your cat has contracted Feline Infectious Peritonitis Virus (FIPV). However, these tests do alert medical professionals to potential infections by detecting the antigen inside your cat's body fluid and faecal matters. Experienced veterinarians use these tests, along with experience and trained eyes to determines the likelihood of an FIPV infection.

1. Titre Test (ELISA Test)

A titre test measures the level of antibodies circulating in the blood. These antibodies are produced when pathogens such as viruses or bacterias produce a response from the immune system.

2. Rivalta Test

A simple yet useful test to determine the WET form of FIP. The test is performed by collecting sample fluid from the cat’s abdominal or chest cavity, adding it to a test tube filled with distilled water and one drop of 98% acetic acid. You can see a video of Rivalta Test performed here.

3. Blood Test

A blood test is the most comprehensive test used to determine the likelihood of a FIP viral infection in cats. The white blood cells might be low, normal or high, depending on how long the Feline Infectious Peritonitis viruses have been present, and if other problems also exist. The red blood cell count might be normal or low (anemia). The biochemistry profile commonly reveals an increase in total protein and globulins. This increase is caused by the inflammatory process occurring as the cat's body responds to the virus. Veterinarians often look at A:G ratios as the first sign of potential FIP infection in cats.

Other tests on the biochemistry profile could, but not necessarily indicate FIP in cats since these problems could also occur with other diseases. For example, if the kidney values are increased in an older cat with suspicion of FIP, some of the possibilities are:

  1. Chronic renal failure along with FIP (this cat has 2 different diseases)

  2. Chronic renal failure with no FIP

  3. FIP causing kidney disease

  4. Dehydration due to FIP

  5. Dehydration due to disease in some other organ

Now that you know the 3 common tests used to determine FIP in cats, share this article with someone who should read this.
