Effects of Pre-Analytical Variables on the Quality of Biospecimens Used to Study Genetic Changes in Cancer

This documented briefing describes the process used to identify and analyze data on the effects of pre-analytical variables on biospecimenns used to study genetic and proteomic changes in cancer. It provides details on the development of the Biospecimen Research Database, a data-curation tool developed to provide a standardized way of consistently recording data on the effects of pre-analytical variables.
