Olfactory testing systems and methods

A method of testing an odor threshold sensitivity of a test subject using an olfactory testing device, the olfactory testing device comprising a pneumatic system operable to deliver stimulants to the test subject and a user interface to receive input from the test subject, the method comprising:

• receiving input at the user interface of the olfactory testing device to perform an odor threshold sensitivity test;
• and
• in response to the input to perform the odor threshold sensitivity test, performing the odor threshold sensitivity test at the olfactory testing device including:
• conducting staircase reversals using n-butanol including operating the pneumatic system to deliver n-butanol test stimulants to the test subject and receiving n-butanol test input from the test subject via the user interface;
• computing an n-butanol odor threshold sensitivity score using data from the staircase reversals using n-butanol;
• conducting staircase reversals using phenylethylamine including operating the pneumatic system to deliver phenylethylamine test stimulants to the test subject and receiving phenylethylamine test input from the test subject via the user interface;
• computing a phenylethylamine odor threshold sensitivity score using data from the staircase reversals using phenylethylamine;
• and
• computing a final odor threshold sensitivity score using the n-butanol odor threshold sensitivity score and the phenylethylamine odor threshold sensitivity score, wherein the final odor threshold sensitivity score is the mean of the n-butanol and phenylethylamine odor threshold sensitivity scores.
