Tests and diagnosis
By Mayo Clinic staffDoctors often recognize polio by symptoms, such as neck and back stiffness, abnormal reflexes, and difficulty swallowing and breathing. To confirm the diagnosis, a sample of throat secretions, stool or cerebrospinal fluid — a colorless fluid that surrounds your brain and spinal cord — is checked for the presence of poliovirus.
