ABSTRACT
The high variability of measured olfactory thresholds in humans reflects very broad range of sensitivity within and among individuals. This can be derived from the strongly compressive nature of olfaction, which makes it relatively hard to compare the size of two stimuli in odor sensation. However, we know that some portion of the variation is the result of extrinsic factors e.g. the method used to measure the olfactory threshold. For this reason, in order to address the bias and reliability of a psycophysical method, we combined the use of the CCCRC (Connecticut Chemosensory Clinical Research Center) test with the step method in 40 normal Korean adults twice a week for the evaluation of threshold. The measured thresholds showed high test-retest reliability and the threshold estimates remained consistent during the testing without trial-biases. Based on the results, we can conclude that a combined test using the CCCRC test and step method can be used in the measurement of olfactory threshold in a clinical context.
