Introduction: There are lot of tests used worldwide to assess olfaction. SniffinŽ sticks and UPSIT (University of Pennsylvania Smell Identification Test) are among the most famous. At our department perfumed coloured markers are used. They are commonly available in stationeries.

We created 5 different methods of examination using perfumed markers and compared them to SniffinŽ sticks test (parts Treshold and Identification). Finaly we choosed one of the method according to correlation coefficients and sensitivity and started to use it in clinical practice.

The aim of this study was to evaluate the influence of colours of the markers on answers of the subjects.

Method: The test consisted of two parts. First of all patient was asked to name the odour and than he/she had to choose the proper name for each odour from four options.

Two groups of subjects were created. One group of them (83 patients) was examined by coloured perfumed markers and onother one by white perfumed markers (46 patients).

Results: The correlation coefficients (perfumed markers and SniffinŽ sticks T+I) were 0,81 and 0,85 in the first and in the second group respectively.

Anosmics (diagnosed by SniffinŽ sticks test) did not reached more than 5 points of perfumed markers test (PMT) in both groups.

Conclusion: We conclude that there is no influence of colours on the results of PMT.
