Olfactory identification tests are useful, both in regular otorhinolaryngological practice and also in scientific studies. Additionally, smell loss might be associated with a number of different diseases, which highlights the importance of proper olfactory testing for specialists from various disciplines. In our study, for technical reasons related to the change of manufacturer, we re-investigated the extended, 32-item Sniffin’ Sticks identification subtest. We reconfirmed that the full, extended test and its two parts are reliable and highly correlated with each other. The extended test was also highly discriminative in terms of a difference between scores of controls and patients with olfactory disorders. Generally, the described test can be used in its full version as a simple tool allowing detailed diagnosis of odor identification, or it could be split onto two individual tests, used for repeated measurements of odor identification overtime
