Vestibular diagnostics cover a wide variety of measures of the vestibular or balance portion of the auditory system. 

These include positioning the head and body in particular ways or presenting different temperatures to the ears and determining how the balance system responds by measuring a patient’s ability to maintain balance, the patient's report of dizziness, or physiologic responses such as eye movements. 

After all of these measures are performed, a clearer understanding is attained regarding the location of such abnormalities along the auditory pathway from the external ear to the top of the brain, and in particular the ability the auditory system’s ability to maintain balance and prevent dizziness.
