In an effort to improve the search coordinator's experience when performing three and/or four mismatch cord blood searches, WMDA is currently developing several features that should improve the efficiency of finding suitable CBUscord blood unit. These are:
- Filter for returning only donors/
...
- cord blood with typing at C (and/or DQB1). Available today.
- Filter on match class
...
- - a search coordinator can go directly to the 5/8 or 4/8 potential matches. Scheduled for delivery December 2022
...
- .
...
- "Score" based sorting for
...
- three and

- /or four mismatch cord blood results (find details below). Scheduled for delivery

- December 2022.

- Match probability calculation for three and/or four mismatches. Scheduled for delivery Q1 2023.
Score based sorting of 3 & 4 mismatch search results (see option 3 in above paragraph)
In general it is true that the more highly typed a CBU/ donor on a match list is, the higher the probability of a match. As we are currently not able to provide match probabilities and it will take a few months to fully develop, we will use a score based approach. This works in the following way
