Hla- Class I – A Locus – [Blood]

Testing is usually performed only in the setting of a planned transplantation where you are either the intended transplant recipient or a possible donor. testing identifies which human leukocyte antigen (hla) genes and antigens you have inherited and detects antibodies to hla antigens that would cause transplants to be unsuccessful; testing may also be done to identify hla antigen types in platelet blood donors that match transfusion recipients.
