The biosafety guidelines in this protocol are based on the Center for Disease Control's Biosafety in Microbiology and Biomedical Laboratories (BMBL), which has served as the cornerstone of biosafety practice in the United States since its initial release in 1984. The information in this protocol was extracted from the BMBL and truncated to provide CHTN VUMC staff members with the knowledge necessary to complete their training requirements. The protocol is used as both a reference and training SOP for the tissue procurement and the bodily fluids/blood processing protocols.
