Can an immunologically, nonreactive potential allograft recipient undergo transplantation without a donor-specific crossmatch?
Performance of the pretransplant crossmatch requires 4 or more hours . Delays in the crossmatch might alter operating room availability and thereby increase donor organ cold ischemia time that might then result in increased risk of delayed graft function. To avoid these problems, recipients could be identified who would be expected to display negative donor crossmatches and who could be transplanted with a concurrent or retrospective rather than a pretransplant crossmatch. We, therefore, evaluated the percent reactive antibodies and donor IgG-antihuman globulin (AHG) crossmatch results of 1165 sera from 220 potential allograft recipients. Twenty-five (11%) of 220 recipients consistently displayed a 0% PRA and, with only one exception, their sera (n= 156) tested IgG-AHG crossmatch-negative against potential cadaveric donors (a 0.6% IgG-AHG positive crossmatch risk). These data suggest that the timing of the pretransplant serum crossmatch could be altered for a highly selected group of immunologically nonreactive recipients.
