A, B Antigen, DRB1 ARD level CBU searches are now available in the sandbox environment (https://sandbox-search.wmda.info/).
It was built to function in the same way as was implemented in legacy Search & Match. This means that:
- Allele matching is used to calculate overall and locus-specific match probabilities.
- Match class (e.g. 5/6, 4/6) is based on Antigen level matching at the A* and B* locus whereas regular matching at antigen recognition domain (ARD) level is used for DRB1.
After confirming it works correctly we will make it available in the production environment (https://searchmatch.wmda.info/)
Known behaviour.
As mentioned, CBUs are assigned the right match class (6/6 vs 5/6 vs 4/6) in A, B Antigen, DRB1 ARD level CBU searches. We are aware of a small issue. In some cases we may not indicate that a locus has a mismatch where there is one. This is only the case in A, B Antigen, DRB1 ARD level CBU searches and not in regular searches. We are working on a fix for this.
