The Terser cannot be used to determine the number of repetitions of a message element. According to the spec, ORC and OBR may appear just once in each ORU_R01_ORDER_OBSERVATION group. So I guess you are referring to the number of ORU_R01_ORDER_OBSERVATION groups in the ORU message?
Maybe you can then use something like int count = oruMsg.getPATIENT_RESULT(0).getORDER_OBSERVATIONReps() This should also be stable across hl7 versions. cheers Christian Carlos Oliva-3 wrote: > > How can the Terser obtain the total number of ORC and OBR segments in an > ORU message?
