29 April 2014 (Tuesday) - Discrepant Blood Group?
An interesting case - a manual blood group: the automated analyser wasn't happy with the results it had obtained. Look at the results of the B cells with the patient's own serum. (Right hand end). Reaction is there, but weak.
The patient has received a bone marrow transplant. Once blood group "O", now he is "B". His natural anti-B antibodies are now disappearing.
