Rules
Intermediate resolution (M) translates to the non-high resolution.
The coding schema theoretically allows more combinations than the previous bitstring (e.g. non-high DRB1 typing). The actually valid combinations have to be published in the national rules of each registry. The local user interfaces will have to take care that no invalid or previously undefined requests are issued.
...
?Only one SMP_REQ can be open for a patient / donor pair (please see also the General section about duplicate requests).Several distinct requests for the same patient / donor pair at a time are possible, for example, a DRB1 high and a class I DNA, but each request has to be answered by a TYP_RES message. It is not allowed to ”concatenate” / ”summarize” results in a single result message. Multiple typing requests for the same patient / donor pair have to be disjoint (i.e. may not contain the same locus or allele). The occurrence of multiple requests should be an exception. Usually, all loci or alleles required should be requested within one message.
The appropriate action if the typing request cannot be accepted or has to be changed by the recipient, e.g. due to national rules, is to inform the requesting side what was done. If only the resolution was changed (the sender will receive something different than ordered - either more or less) or only a part of the requested loci were accepted (the sender will only receive parts of what was ordered): send a MSG_RSP containing the warning.
