Antibodies to inner ear antigen (68kD) occur in approximately 70% of patients with autoimmune hearing loss. The antibody tests to this 68kD antigen parallel with disease activity. In addition, a majority of patients positive for antibodies to 68kD are responsive to corticosteroid treatment. (Hirose et al: The Laryngoscope 109:1769-1999)
