Such tissues and organs may be referred to as implant tissue, allograft, xenograft, skin graft tissue, human transplant tissue, or implant bone. Tissue is stored in tissue establishments or tissue banks under cryogenic conditions. Fluids such as blood, blood products and urine are stored in fluid banks under similar conditions.
The collection, storage, analysis and transplantation of human tissue involves significant ethical and safety issues, and is heavily regulated. Each country sets its own framework for ensuring the safety of human tissue products.
- Donor Screening and Testing: the determination of donor suitability for human tissue intended for transplantation.
- Procedures and Records: the written procedures and records that must be kept
- Inspection of Tissue Establishments: the importation of tissues from abroad and the retention, recall, and destruction of human tissue.
