Example of an NMDP search report. The columns labeled “HLA Typing/Match Grade/Calculation” include a letter indicating the match status of each allele at the locus indicated (A indicates allele match; P, potential allele match; and M, mismatch), the probability of matching both alleles at the locus (99% for the first donor at each locus). The columns labeled “Composite Predictions” display the probability of a 10 of 10 HLA-A, -B, -C, -DRB1, -DQB1 allele match (99% for first donor) and 8 of 8 HLA-A, -B, -C, -DRB1 allele match (99% for the first donor).
