At a glance:
The system changes related to updating the HLA equivalency tables and adding DQA1 equivalences are now in effect. Although we originally planned to implement this system change on August 29, we changed that date to September 12 because of a patient safety-related concern brought forward by the transplant community during beta testing.

Consequently, as of today, we have implemented all of the changes detailed in the initial system notice, except for the allele-level typing options for DR51, DR52 and DR53.

We did not add the following options:

  • For DR51: 5*01:01 and 5*02:02
  • For DR52: 3*01:01, 3*02:02 and 3*03:01
  • For DR53: 4*01:01 and 4*01:03
