Tests and diagnosis
By Mayo Clinic staffDoctors often can identify Ramsay Hunt syndrome based on medical history, a physical exam and the disorder's distinctive signs and symptoms. To confirm the diagnosis, your doctor may take a sample of fluid from one of the rash blisters in your ear and perform a polymerase chain reaction (PCR) test on it. This test can detect the varicella-zoster virus. A PCR test can also be done on a blood or tear sample. But, testing fluid from your ear offers more-reliable results.
