T&T Olfactometer for Standardized Olfactory Test and Its Uses

Abstract

Today, most countries have standardized methods for testing vision and hearing. However, there are no set rules anywhere in the world for testing the olfactory sense, despite a growing need. To answer this need, an olfactory sense test has been developed, which uses a testing device called the T&T Olfactometer (Daiichi Yakuhin Sangyo, Tokyo, Japan). In 1975, a study group was set up with funding from the Ministry of Education and Cultural Affairs of Japan to formulate standards for testing the sense of smell. A further study group, under Professor Sadayuki Takagi of Gunma University, funded by the Ministry of Health and Welfare, was set up in the same year to research treatment for the impairment of the olfactory sense.
