Interesting case, and I agree entirely that the patient should be excluded from electronic issue, but how this decision be made known to any other hospital?
I am somewhat surprised that the RCI Laboratory did not pursue the case further, unless no further samples were available, given that the patient underwent a classic acute haemolytic transfusion reaction, but I would also dispute that they tested the plasma against many (sufficient) low prevalence antigens. Of those you list, Do(a), Do(b), Lu(a) and Kp(a) would all be classified as polymorphic in the UK greater than1% expression in the population - although I fully realise that this classification is NOT the same throughout the world), and Co(a) is a HIGH prevalence antigen. In reality, therefore, the only low prevalence antigen against which they appear to have tested the plasma is Wr(a).
It may be helpful in such a case to know the ethnicity of the patient, the sex and, if female, any pregnancies (and if these all went to term, or were any of the babies affected by HDFN), and, if the male partner is still available, whether or not his red cells could be typed and, possibly, tested against the patient's plasma (assuming for the moment, the patient is a female).
I really am somewhat amazed that the RCI Laboratory did not submit a sample to the IBGRL.
