Abstract
Is the lower rate of kidney transplantation into African Americans medically and ethically justifiable? Or is it a form of racial discrimi nation comparable to if not worse than denial of employment opportunities, housing, and educational opportunities? This essay focusses on the medical problems associated with matching antigens in donors and recipients, and the implications of those problems for social justice.1 Racially discriminatory practices in bank lending, education, and hiring provide a context for understanding how medical criteria treat black recipients unfairly. Although antigen matching is only one aspect of the general problem of finding medically suitable black recipients, it presents an especially interesting challenge for theories of justice, as well as for medical research.
