If an AN is suspected, a detailed patient history and a thorough otologic and neurotologic physical examination should be carried out. The first echelon of diagnostic testing begins with a pure tone audiogram, speech reception threshold, speech discrimination testing, and acoustic reflex testing. If the clinician is even moderately suspicious of the presence of an AN, the patient should undergo a Gd-MRI scan. If suspicion is low, an ABR should be performed, and if negative, the patient should be reevaluated periodically.
