RESUMO
A simple olfaction test, based on graded solutions of phenol in liquid paraffin, was examined for repeatability. Of 98 persons tested, 79 repeated their initial result to within ± one grade on a second occasion. The time interval between tests (varying from a few hours to three weeks), observers, age, smoking habits, or initial grade did not appear to affect the degree of repeatability. There was a tendency to improve the grading on the second occasion.
