Abstract: The invention relates to a method for determining a risk of permanent rejection of a graft after being transplanted to a recipient, said method being characterized in that it includes the following steps: (a) entering physiological/clinical characteristics of the recipient and the donor into a computation unit by means of an input interface, said characteristics including the gender of the recipient, the creatinine level of the graft donor when sampled, the age of the recipient at the time of the transplant,—the number of renal transplants previously received by the recipient,—a creatinine level of the recipient measured twice at at least one predetermined point in time after the transplant, a proteinuria level of the recipient measured at a predetermined point in time after the transplant, and the existence of an episode of permanent rejection of the transplant during the first year of the transplant; (b) determining the parameters on the basis of said characteristics; (c) combining said parameters so as to
