THERE IS NO "FIP TEST".

Proper diagnosis requires a variety of tests to both confirm FIP and rule out other diseases that share similar symptoms. What is sometimes (incorrectly) called the "FIP test" measures the cat's exposure to FCoV. 95 percent of the world's cats population have been exposed to FCoV. These titer tests are NOT conclusive. A positive titer for FCoV does NOT indicate that the cat has FIP.
