Histocompatibility Laboratory

The Histocompatibility Laboratory is ASHI-certified and performs the testing required for bone marrow and solid organ transplantation services at Massachusetts General Hospital.

Tests include both serologic and DNA-based HLA typing; determination of HLA antibody frequency (PRA) and specificity using cytotoxicity.

The lab also does HLA typing and antibody testing required by the Mass General Blood Transfusion Service and Blood Donor Center. Total HLA lab test volume is approximately 11,000 tests per year.
