Donorrecipient

The term donorrecipient denotes the relationship in which a donor provides biological material to a recipient in medical transplantation and related therapies. Donorrecipient dynamics are central to organ, tissue, and cell transplantation, as well as blood donation and stem cell therapies. The concept covers living donors, deceased donor programs, and paired exchange arrangements designed to increase compatibility and access.

Prior to transplantation, donorrecipient evaluation assesses safety and suitability for both parties. Compatibility testing typically includes ABO blood type, HLA typing, and crossmatching to reduce rejection. Allocation systems weigh medical urgency, wait time, and logistics, while registries compile donor and recipient information to support matching for solid organs, bone marrow, and stem cells.

The process involves donor assessment, procurement, preservation, surgical transplantation, and post-operative care. Recipients receive immunosuppressive therapy to prevent rejection, and ongoing monitoring addresses graft function and adverse effects. When direct donor–recipient compatibility is lacking, paired exchange or multi-way exchanges enable successful transplants between multiple pairs.

Ethical and legal considerations cover informed consent, donor safety, privacy, and equity of access. Policies regulate donor risk disclosure and compensation practices, with varying rules across jurisdictions. Data collection and oversight aim to protect donors and recipients while improving outcomes and fairness in donorrecipient matching.

Outcomes depend on the organ or tissue transplanted, recipient condition, and advances in immunology and surgical care. Survival and graft function have improved significantly in many settings, though long-term success hinges on treatment adherence and follow-up.
