BACKGROUND AND OBJECTIVES: The olfactory identification test has been used in clinical assessment of olfactory ability for the following reasons: it is fast, it yields results compatible to a threshold test, and it gives a picture of how well the patient can deal with odors of everyday life. However, items in UPSIT (University of Pennsylvania Smell Identification Test)and CCCRC (Connecticut Chemosensory Clinical Research Center)identification test which are widely used in the world are selected for western people. Accordingly, these items in the tests are not appropriate for Koreans of different cultural background.
MATERIALS AND METHODS
For the selection of proper items for the olfactory identification test, 42 natural odors familiar to Koreans were applied to 40 normal subjects and 40 patients with decreased sense of smell without sinonasal diseases. Among 42 items, 16 items with high identifiability and familiarity were chosen according to the results of test-retest in normal subjects.
RESULTS
The results of olfactory identification test using 16 selected items showed high correlation with olfactory threshold.
CONCLUSION
These 16 items can be used for an olfactory identification test for Koreans.
