Abstract
In this article, we attempt to get to the basics by discussing the antigens and antibodies as they relate to the transplant surgeons. Analysis of the current data from individual centers and the United Network of Organ Sharing database is used to delineate some guidelines. Judicious judgment will allow many of these organs with positive viral serology to be transplanted into appropriate recipients with minimal incremental risk. © 2003 Lippincott Williams & Wilkins.
