Interpretation

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