New Analysis Determines HLA Match Rates in Be The Match Registry

A new analysis of the Be The Match Registry ® has determined that 7/8 HLA match rates are >80% for all four of the most frequent patient race/ethnic groups in the United States - White (WH), Hispanic (HIS), Asian/Pacific Islander (AIP), and African American (AFA). Researchers analyzed 1,344 high-resolution (HR) typed potential unrelated donors (URD) in the Be The Match Registry who were randomly selected and treated as pseudo-patients where HR testing was performed to identify a 7/8 or better match rate. The highest 7/8 or better match rate was found in the WH group at 98% followed by HIS 86%; API 88%; and AFA 82%. Research has shown that using an HLA mismatched URD in early disease stage is associated with higher overall survival than delaying transplant to a more advanced disease state. The researchers noted that the baseline HLA match rates established in their study can be increased by accessing additional worldwide registries.
