Equitable Distribution

The institutions and Principal Investigators comprising the CHTN make every effort to ensure that there is an equitable distribution of tissue into and by the CHTN. Investigators requesting tissue samples can help the CHTN fulfill our mission by requesting as small a sample as possible.

Access to specimens varies according to the surgical schedules and autopsy rates and is thus, not predictable. Therefore, investigators requesting fresh specimens should make every effort to use these specimens when they are made available. Investigators will be charged a processing fee for refusing samples collected according to their protocol.
