Performed: Thurs

CPT Codes: 83516

Performed By: Referral Lab

Clinical Utility: Not recommended for evaluation of general hearing loss.  The presence of HSP70 IgG antibodies may be useful in predicting corticosteroid responsiveness in a subset of patients with autoimmune inner ear disease (AIED) characterized by idiopathic rapidly progressive sensorineural hearing loss (SNHL). HSP70 IgG antibodies are also associated with a number of autoimmune diseases and have also been reported in apparently healthy individuals. A negative result does not rule out response to treatment or to a diagnosis of AIED.
