Solid Phase Assays
In addition to HLA high resolution typing, patients are screened for preformed anti-HLA antibodies; the detection of anti-HLA antibodies directed to possible mismatches in less ideal donors is related with delay in the platelets and neutrophil engraftment and even with graft rejection. Panel reactivity antibody (PRA) indicates the degree of reactivity of tested serum in terms of percent of positive reactions when tested against a panel of known HLA phenotypes.
For positive results, the report will define the detected HLA antibody specificities. For negative results, 0% PRA will be reported.
