HLA matching

Pronunciation

Definition 1

A process in which blood or tissue samples are tested for human leukocyte antigens (HLAs). HLAs are molecules found on the surface of most cells in the body. They make up a person’s tissue type, which varies from person to person. They play an important part in the body's immune response to foreign substances. HLA matching is done before a donor stem cell or organ transplant to find out if tissues match between the donor and the person receiving the transplant. Also called human leukocyte antigen matching. (NCI Dictionary)

Definition 2

A process in which blood or tissue samples are analyzed to determine their human leukocyte antigen (HLA) profiles so that transplant materials can be transfered into a patient with the same or similar profile. (NCI Thesaurus)
