Key points
The aim of the study was to design a test that can detect the olfactory
function of Chinese people more comprehensively.
We collected odor familiarity questionnaires to screen familiar odors of
Chinese people.
Three odors (tetrahydrothiophene, 2-methylpyrazine, and trimethylindole)
can simulate natural gas, burnt smell, and fecal odor, respectively.
In this study,the Sniffin’ Sticks Olfactory Identification test was
modified from the distractors and odors.
Through the modification, the scores of olfactory identification test
were significantly improved.
