Feature | Optimatch | HAP-E | ATLAS |
---|---|---|---|
AB search | Yes (separate search) | Included in standard search (only n/n and n-1/n) | No |
ABDR search | Yes | Yes | Yes |
AB Antigen, DRB1 allele match (for cord matching) | Yes | To Do | No |
Sorting performed by Matching Engine | Yes | No | Yes |
Information about probability of match at other allele at already mismatched locus | No | Yes | No? |
Flexible scaling to accommodate periods of high and low use of the engine | No | Yes | Yes |
Easy updating of HF Sets | No | Yes | Yes |
g group level matching | Yes | Yes | No |
G group level matching (leading to less populations and lesser performance for some of populations, but better matching for other populations). | No | No | Yes |
automatic refresh of patient searches | Yes | No | ? |
differential results from matching algorithm. → algorithm tells what has changed. | No | Yes | No |
HLA validation of DRB3, DRB4, DRB5, DQA1 and other loci not considered for matching | No | Yes | ? |
Performing a mismatch search will return also (potentially) matched results | Yes | Yes | No (currently) for donors, Yes for cords |
Amount of searches that can reasonably run in parallel | 3 | 12 | |
consider combination of serological and dna typing for match probability | Yes | No | No |
support for > 2 mismatches | No | will be done. >=4/8 all loci to be considered need to be typed at high resolution for patient. | yes, >= 4/8 |
HLA imputation based on patient organisation and/or pool | No | Yes | ? |
mismatches per locus can be sent directly to matching engine? | Yes, during actual search and during retrieval. | No. Server side filtering needed for API and GUI | Yes, but not fast. For performance reasons will perform server side filtering for GUI use. |
null allele handling | Does not return donors with XX or also with some MAC codes? Not matching homozygous typing. | will return donors which match haplotype with known null allele. Will be marked in search results. | ? |
