The University of Pennsylvania Smell Identification Test (UPSIT) is a test that is commercially available for smell identification to test the function of an individual's olfactory system. It has been administered to about 500,000 patients to this date. It is the gold standard of smell identification tests for it's reliability (r=.94)[1] and practicality. For example the test can be performed during a matter of minutes in a waiting room and the results can received soon after that. Richard Doty invented UPSIT which has been used as a self-examination test in the diagnosis of many diseases including Parkinson's Disease and Alzheimer's. The test has been altered in several ways to be useful in different languages and cultures. There are also several trends that are found when UPSIT is administered based on demographics such as age, gender, history of smoking and other characteristics. [2]
