DEVICE: Sensonics' Snap & Sniff Eco-Friendly Olfactory Test System (G051SNSI0)

Device Description: The Sensonics 16-item odor identification test is a member of the Snap & Sniff® Olfactory Testing System family. This test, along with the other members of the family, was developed to provide scientists, clinicians, and others with a standardized, easy-to-use, and reliable means for evaluating the ability of subjects to identify odors. Detailed instructions are provided in an accompanying manual to acquaint the test administrator with the details of proper test administration. The test employs the following familiar odorants: mint, lemon, leather, banana, orange, paint thinner, garlic, licorice, cloves, pineapple, apple, rose, coffee, fish, cinnamon, and chocolate. The S&S-I is comprised of 16 smell “wands”. The odor of a given wand is contained within a proprietary odor emitting cartridge. When the thumb of the operator pushes forward on a slide mechanism, the odorized tip is exposed for sampling and presented to the subject. Releasing the slide retracts the odorized tip back into the wand’s housing. The Snap & Sniff® mechanism results in an easy presentation of an odorant to a subject. Because the odorant tip is presented only briefly, the odor is retained for much longer periods and can be used for testing many more subjects than devices lacking such sophisticated technology. Liquids, per se, are not present in the sniff wands.
