Investigators who request tissue must provide documentation of IRB approval or exemption status. Samples will be coded. A limited amount of demographic data linked to each sample can be provided (i.e., diagnosis, age at death, and gender of the person from whom the sample was obtained). Requests for additional data will need to be reviewed and approved by either the Tissue or Executive Committee. The investigator must specify what additional demographic data are needed at the time the application is submitted, and not at the time the samples are distributed. You may only utilize these samples for the purpose for which you were approved. Destroy or return unused samples as indicated in your approval letter. Investigators are responsible for all costs related to shipping/delivery of the requested samples.
