Validity and Reliability of the Diagnostic Tests for Ménière's Disease.

Ménière's disease is defined as an idiopathic syndrome characterized by endolymphatic hydrops. Various tests and measurement methods have been employed for the diagnosis of Ménière's disease. These include audiological, vestibular, radiological, clinical, and biochemical tests. However, the lack of a definitive or gold standard diagnostic test sometimes complicates the process of diagnosis. Hence, the clinician should be well-experienced in deciding when to perform a test and how to interpret the results of the test. Furthermore, having the knowledge of the validity and reliability of these tests plays a critical role. This review particularly emphasizes on remarking the validity and reliability of each test performed for the diagnosis of Ménière's disease and discussing the results according to the up-to-date literature.
