Adult Volunteers Needed to Complete Four Different Smell Tests

Adults between the ages of 18-85 may qualify for a research study to validate SCENTinel, a newly developed rapid smell test to screen for smell loss, against three other commercially available smell tests: NIH Toolbox Odor Identification Test, B-SIT, and Sniffin Sticks. This study involves 2 visits to the Monell Center.

One session is 1.5-hrs-long and compensated at $30, and the other is 0.5-hrs-long and compensated at $15, for $45 dollars in total compensation.

The second session is scheduled two weeks from/after the first session.

Subjects 18 to 55 Needed for Paid Study

Subjects ages 18 to 55 years qualify for a study where participants will be asked to detect, identify, discriminate, and evaluate different smell stimuli. Compensation is $15/hour + $5 for transportation per testing session. You may be invited back for additional sessions. Study visits (lasting up to 2 hours) during which you will be asked to smell different odors are involved.

Sense of Smell and COVID-19

Do you want to test your sense of smell from home?

Have you recently experienced any flu symptoms?

You may qualify for a scientific study, performed by the Monell Chemical Senses Center, about the sense of smell and how the flu/COVID affects it.

Information about the test:

  • You will receive by mail a set of scratch and sniff odor cards with instructions on how to use them and how to access the website where you will write your answers.
  • It will take about 15-20 minutes to perform the odor test and complete few demographic and health questions.
  • The test will be performed online at your convenience.
  • You will need access to the internet and a physical address so we can snail mail the scratch and sniff odor cards.

This field is for validation purposes and should be left unchanged.

You are being asked to provide information about yourself for a central file to be used by Monell researchers ONLY.

Monell researchers may use the information in this file to contact you about future research opportunities. In addition, the central file may be used to furnish funding agencies with basic descriptive information about participants in Monell studies (e.g., number of participants, ages, gender, etc.). You will not be identified by name in any information provided to outside agencies.

Your participation is completely voluntary and you may say no to any study team which contacts you without fear of being overlooked for future studies. You need only complete the requested information. There are no risks or costs to you, and you will not be compensated for providing the information. Further, you may withdraw your information from the file at any time by calling Monell at (267) 519-4813.

We appreciate your participation in our research and offer this as an opportunity for other research teams to recruit you for their studies. However, if during the course of a study you do not comply with the research protocol, you might not be contacted for further studies.

Neither filling this form nor being added to the database is a guarantee that you will be contacted in the future.

Every attempt will be made by Monell staff to maintain strict confidentiality for all information collected in the central file, except as may be required by court order or by law. Authorized representatives of the University of Pennsylvania and the Monell Chemical Senses Center will have access to and may copy information from the central file which may identify you by name.
