Objective:
To know the values of the olfactory test (CCCRC) performed in healthy people. To analyse how the age and sex affect the test.
Material And Methods:
Descriptive study in 100 volunteers with no olfactory disorders. We used CCCRC olfactory test, which it has an odor threshold component, an odor identification component and a composite score. We analysed how age and sex variables affect olfactory test data, listing a t-Student test. The size sample is calculated to 0.05 alfa error.
Results:
Threshold test data mean was 5.8. Identification test data mean was 7.5. Composite score mean was 6.7.
Conclusion:
Age is a significant factor in our study but not sex. Sample size is sufficient to analyze normal values. Our results are similar to other authors.
