Abstract
BACKGROUND: Smell impairment affects 1% to 2% of Americans and leads to frequent physician visits. Olfactory testing is available in chemosensory centers, but not as part of a routine cranial nerve examination. The alcohol sniff test (AST), which uses the standard 70% isopropyl alcohol pad, was developed as a quick, reliable measure of olfactory function. METHODS: Sixty-four patients and 36 healthy control subjects (N = 100) were tested with the AST and with a standard butanol threshold test. RESULTS: The AST reliably, consistently, and correctly measured olfactory function. CONCLUSIONS: The AST is a rapid, reliable olfactory test that can be used for screening olfactory function and should be incorporated in the routine cranial nerve examination.
