cze Screening čichové funkce pomocí parfémovaných fixů. Cílem studie bylo vytvořit screeningovou metodu vyšetření čichu za pomocí parfémovaných fixů. Bylo vyšetřeno celkem 189 osob (zdravých i osob s postižením čichu). Čich byl testován pomocí 5-ti různých metod za použití parfémovaných fixů a zároveň testem Sniffin´Sticks. Korelace jednotlivých metod s testem Sniffin´Sticks byla 0,49 - 0,93. Nejlepší metoda screeningového vyšetření dosáhla vysoké sensitivity a dostatečné specificity k detekci anosmie. Závěr: Test parfémovaných fixů může být použit k záchytu anosmie v populaci. Přesné hodnocení čichové funkce však pomocí tohoto testu pro malý počet pachových látek není možný.

eng Screening of olfactory function using odourized markers. Background: The goal of our study was to create a psychophysical test for the screening of olfactory function on the basis of commercially available odorized markers (OM). There are six colored markers in one package filled with different odorants in suprathreshold levels. In order to identify the best approach, we investigated five different variations of the technique. Materials and methods: Olfaction was investigated in 189 subjects. Healthy participants as well as patients suffering from olfactory disorders were tested. Initially subjects were tested by one of five methods using OM. Finally, the ?Sniffin? Sticks? test (butanol odor threshold, odor identification) was performed. Results: Correlation of the OM screening test and the ?Sniffin? Sticks? ranged from 0.49 to 0.93 indicating that variations of the technique strongly influence the results of testing. The best technique for evaluating olfactory function included spontaneous naming of odors and odor identification from a list of four distractors. The sensitivity of this method was sufficient to determine anosmia. Conclusions: The odorized markers screening test can be used to screen anosmia in the general population. However, the precise quantification of olfactory function is not possible, because of the relatively small amount of odors. Odourized Markers;Sniffin´Sticks;Olfaction;Screening Test.
