How do vets determine if a dog has rabies?

The direct fluorescent antibody test (DFA) is the test most frequently used to diagnose rabies. This test requires brain tissue from animals suspected of being rabid and can only be performed post-mortem. If you don’t want to kill your pet, there are also many veterinarians who choose to test for real-time PCR test.
