Here’s
an interesting case I found on one of the Facebook work-related groups I
follow…
“Hey, guys! We have a patient at work who is
a real mystery and was hoping someone could point us in the right direction or
give some insight.
He's an oncology
patient that we've been seeing for about a year now. He's given regular
transfusions about once a week. He is A neg, and we always give him A or O neg
units. Last week his screen finally popped up positive but after rule outs and
everything, it seems like an obvious anti-D. However, we've never given him
anything RH positive, no platelets or anything. He's only ever received red
blood cells from us.
He's not on IVIG, and
has not been to another hospital in recent times. We've tested the previous
blood units transfused on him and they're weak D negative. His sample is pretty
unique with mix field from his previous O transfusions so we're pretty
confident that his samples are his. We've had three separate samples since then
and all screens are positive.
We thought he maybe
went to an ER somewhere and was transfused platelets since his platelet count
was low and was given RhIG or something but he denies going anywhere else.
Any idea where he got
the Anti-D from? Let me know if you have any questions or more information.”
The
chap’s only ever had D-negative blood… where has the anti-D come from?
Has
he *really* only ever had D-negative
blood?
My
father recently found out he was given a blood transfusion during is his
surgery of last year whilst he was unconscious…
