Abstract
The olfactory test battery "Sniffin'Sticks" comprises a perception threshold test, an odour discrimination test and an odour identification test. The purpose of this study was to examine the suitability of the Sniffin'Sticks for use in everyday practice and to obtain (at least provisional) normal values. Thirty normosmic and 15 anosmic volunteers were examined with the Sniffin'Sticks and the "University of Pennsylvania Smell Identification Test" (UPSIT). All three Sniffin'Sticks tests distinguish between normosmics and anosmics in a highly significant manner. The good correlation of the individual tests with each other and with the results of the UPSIT documents the reliability of the test results. Critical mention must be made of the overly complex determination of the olfactory threshold. In conclusion, the Sniffin'Sticks test battery provides a validated instrument adapted to European conditions for the examination of olfactory disorders. It has proven successful in everyday clinical practice and constitutes a major aid for compiling medical certificates.
