Nondonor

Nondonor is a label encountered in medical and bioethics contexts to indicate that no donation is involved from a particular individual for a specific purpose. The term is not a universally standardized category and its exact meaning can vary by jurisdiction and field. In organ transplantation, donors are usually living or deceased; nondonor status may be used in records to denote that a person neither donated organs nor tissues in a given case, due to medical unsuitability, lack of consent, or opting not to donate. In fertility medicine, nondonor cycles refer to assisted-reproduction treatments that use the patient’s own gametes rather than donor eggs or sperm. In some administrative or research settings, the term may also be used to distinguish between donor-derived materials and non-donor materials used in a study or clinical workflow. The concept intersects with ethics and policy around consent, disclosure, and allocation, as donation decisions are typically bound by local laws, organ and tissue donation registries, and institutional guidelines. Because the term is not uniformly defined, readers should consult the relevant jurisdictional or institutional documentation for precise scope and usage.
