Biosamples

The Survey of the Health of Wisconsin maintains a state-of-the-art biorepository of population-based biosamples. Our specimens are available to researchers from the University of Wisconsin-Madison as well as other research institutions.

Our biorepository inventory contains only samples for participants who consented to having samples stored for future unspecified research. Although not required, it is advisable to contact us to discuss research ideas and learn more about the SHOW biorepository data and availability prior to making any biosample requests.

Requesting samples:

  1. Check availability of biospecimens in the tables below and determine if you need one or more aliquots per sample. You can also submit a biospecimen availability inquiry form.
  2. Submit a biosample request form to data@show.wisc.edu. You can request specimens based on a number of specific criteria outlined in the form.
  3. The SHOW scientists will review your request and will make recommendations for approval. This process may take up to two weeks.
  4. We will notify you if your request receives approval and will arrange sample distribution.
  5. For most studies, we will require IRB approval prior to the use of SHOW biosamples.

Please contact us if you have any questions.
