Biomonitoring Methodologies to Measure DNA Adducts in Urinary Cells

What is the purpose of the study?

The purpose of this pilot study is to determine the usefulness of urine as a biospecimen for examining biological markers (biomarkers) related to bladder cancer.

How often are the clinic visits?

There will be one virtual meeting to discuss the study details, sign the consent form, and complete the questionnaires via online links (~1 hour). You will then pick-up your sample collection supplies curbside from the study staff at the University of Minnesota. The urine collection will be done at home. The day that you complete your urine collection you will need to return your sample to the study staff (curbside) by 3pm.

What will I be doing in the study?

You will complete questionnaires about your demographics, medical and medication use history, tobacco and alcohol use history, recent dietary habits, and exposure to chemicals, smoke, and vape. You will then be asked to collect all your urine from when you first wake up in the morning and for 6 hours afterwards, and record any tobacco or alcohol use the day before and the day of your urine collection. You will then return your urine sample by 3pm on the day of the collection.

Will I be compensated?

Participants who complete the urine collection and questionnaires will be compensated $50 when they return their completed urine sample.

What should I do if I have any questions?
