DONOR: If the patient is homozygous at the mismatch HLA class I locus or II locus, the donor must be heterozygous at that locus and one allele must match the patient (i.e., patient is homozygous A*: and donor is heterozygous A*:, A*:); this mismatch will be considered a one-antigen mismatch for rejection only DONOR: Patients who are homozygous at the mismatched HLA class I locus or II locus, the donor is excluded if homozygous at the mismatched locus (i.e., patient is homozygous A*: and donor is homozygous A*:); this type of mismatch is considered a two-antigen mismatch and is not allowed DONOR: Donor-recipient pairs in which the HLA-mismatch is only in the host-versus-graft (HVG) direction; patients are homozygous and donor is heterozygous DONOR: Patient and donor pairs must not be homozygous at mismatched allele DONOR: Patients who are homozygous at the mismatched HLA class I or II locus, the donor is excluded if homozygous at the mismatched locus (i.e., patient is homozygous A *: and donor is homozygous A *:);

this determination is based on the standard practice of the individual institution; the recommended procedure for patients with of HLA allele level (phenotypic) match is to obtain a panel reactive antibody (PRA) screens to class I and class II antigens for all patients before HCT;
