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.

Until the development of the Smell Identification Test™, also known as the University of Pennsylvania Smell Identification Test (UPSIT), no convenient means for subjectively assessing smell function was generally available. By incorporating microencapsulation technology and sound psychometric principles into a simple test format, the Smell Identification Test™ filled this void. Although this test was initially designed to provide only a first-step olfactory “screening” function, it became quite clear early on that the test was much more broadly useful than first envisioned and had applicability in numerous clinical, laboratory, and industrial settings. Indeed, the Smell Identification Test™ was found to be more reliable and to correlate more closely in the clinical setting with patient complaints and other indices of dysfunction than more traditional threshold and suprathreshold psychophysical methods. The Smell Identification Test consists of four envelope-sized booklets, each containing ten “scratch & sniff ” odorants. The odorants are embedded in 10- to 50-um urea-formaldehyde polymer microencap- sules fixed in a proprietary binder and positioned on brown strips at the bottom of the test booklets. The stimuli are released by scratching strips with a pencil tip in a standardized manner. Above each odorant strip is a multiple-choice question with four alternative responses. For example, one of the items reads: “This odor smells most like: a) chocolate; b) banana; c) onion; or d) fruit punch.” The test is forced-choice; i.e., the subject is required to mark one of the four alternatives even if no smell is perceived.

The Corowell COVID-19 Symptom Screening Test is intended to objectively testing of the sense of smell. It enables the identification of subjects whose olfactory perception is deviating, restricted or newly got lost. The Corowell COVID-19 Symptom Screening Test is a device for home use. The Corowell COVID-19 Symptom Screening Test can be performed self-administered by the subject. The target population is adults over 18 years of age.

The Odor Quartet is a training kit consisting of 4 olfactory pens used to improve the sense of smell. The effect of the olfactory training is based both on stimulation of the olfactory mucosa in the nose and on an improvement of sensory impressions in the brain. The Odor Quartet consists of 4 olfactory pens, which release different scents: i.e. lemon, rose, clove and eucalyptus.

The Screening 12 Test is intended to be used for examination of smell disorders on humans. The test result can be used to differentiate between Normosmia, Hyposmia, and Anosmia, if the patient is cooperative.

Refill Kit for the Extended Test: The Extended Test (also called “TDI-Test“ – Threshold, Discrimination, Identification) consists of 3 individual tests. A threshold test, a discrimination test and an identi-fication test. Each of these tests generates a number of points, which is added up to the TDI score at the end. The user is given a diagnostic classification of the patient's ability to smell. This is done by evaluating the number of points achieved. For the score, also called TDI score, there are standard values, which were determined by a validation study. The maximum number of points is 48, which is divided between the 3 tests.
