HLA Matching for Kidney Transplantation Steve Takemoto, Friedrich K. Port, Frans H. J. Claas, and Rene J. Duquesnoy INTRODUCTION Histocompatibility testing is an essential component of a successful kidney transplant program for two fundamental reasons. First, human leukocyte antigens (HLA) play a central role in the cellular and humoral immune reThe crossmatch methods were all based on complementdependent lymphocytotoxicity and a steadily increasing number of laboratories used the more sensitive AHG method rather than CDC. There was considerable interlaboratory variability in the crossmatch results: 21 of the CDC crossmatches and 36 of AHG crossmatches failed to reach the 90 consensus threshold. hla crossmatch methods

How can the answer be improved? Crossmatching is a test done just before transplant. A crossmatch determines if your body already has antibodies formed against the donor's antigens. It is very important to know if you have antibodies against a possible donor, because if you are incompatible with that donor you would not be able to safely receive a transplant from himher.hla crossmatch methods HLA Crossmatch Tests. Nearly 600 different HLA molecules have been identified. Through a blood test, the laboratory determines which HLA markers are present. HLA markers are inherited. There are six HLA markers that are looked at for transplantation purposes.

Detection of the presence of autoantibodies (HLA) in a solid organ recipient. T and Bcell crossmatch detects the presence of antiClass IClass II HLA antibodies in the patient. hla crossmatch methods Human leukocyte antigen. The human leukocyte antigen ( HLA) system or complex is a gene complex encoding the major histocompatibility complex (MHC) proteins in humans. These cellsurface proteins are responsible for the regulation of the immune system in humans. The HLA gene complex resides on a 3 Mbp stretch within chromosome 6p 21. May 01, 2010  This introductory review seeks to provide a brief summary of the immunobiology of the HLA system and methodology for HLA typing, antibody screening and identification and patientdonor crossmatching, as a basis for a consideration of the importance of HLA matching, antibody screening and crossmatching in the systemspecific reviews which follow. In transfusion medicine, crossmatching or crossmatching is testing before a blood transfusion to determine if the donor's blood is compatible with the blood of an intended recipient. Crossmatching is also used to determine compatibility between a donor and recipient in organ transplantation. Compatibility is determined through matching of different blood group systems, the most important of Histocompatibility Testing Methods! HLA typing is done by serological typing methods or molecular typing methods. The serologic HLA typing methods detect the epitopes of the HLA molecules, whereas the molecular methods detect the nucleotide sequences. i. HLA typing that defines groups of alleles (usually approximating serologic specificities)
