Abstract

Dizziness is one of the most common complaint leading patients to visit their primary care physicians in older people. Despite its frequency, symptoms of dizziness can be difficult for the physician to categorize. Also many dizzy patients have hearing loss. The evaluation of patients with dizziness depends on not only the history of dizziness, physical findings but also basic laboratory tests such as audiometry, caloric test and ocular motor test. Based on these considerations, this article outlines the interpretation of basic laboratory tests which is fundamental in evaluating dizzy patients.
