Comparison of immune assays for the detection of anti-HSP70 antibodies in patients with idiopathic sensorineural hearing loss

Our data suggest that the antigenic targets in WB and ELISA immunoassays differ and demonstrate that the anti-HSP70 IgG WB test is reproducible within and between clinical laboratories. Thus, in the absence of disease-specific markers, the anti-HSP70 IgG WB assay could be of use to detect patients with idiopathic SNHL who might benefit from steroid treatment.
