Cpra sensitization
WebDec 1, 2024 · The definition of sensitization is variable, but the general consensus is a panel-reactive antibody (PRA) value of greater than 20%. In further characterizing a kidney transplant recipient to be highly sensitized, the level is even more variable, with prior literature starting at a PRA of 80% and above [ 9 ]. WebTools. A panel-reactive antibody ( PRA) is a group of antibodies in a test serum that are reactive against any of several known specific antigens in a panel of test leukocytes or purified HLA antigens from cells. It is an immunologic metric routinely performed by clinical laboratories on the blood of people awaiting organ transplantation.
