I thought I had better do a BTLP-TACT exercise as it is two weeks since I last had a go. I was presented with samples from two patients:
59154 – a twenty-one year old chap from the haematology clinic requiring
two units of irradiated blood for the next day. He grouped as A Rh(D) Negative
with antibody screen positive in cells one and two.
I
requested antibody panels. The IAT panel was positive in cells one, two, three
and four, as was the enzyme panel. This was consistent with anti-C and anti-D
but couldn’t rule out anti-Cw
I selected
two irradiated units of blood which were D-Negative and C-Negative
11440 – a fifty-two year old chap in out-patients requiring group and save. He grouped as B Rh(D) Positive with a negative antibody screen.
I got the red light. Fail. Quack Quack Oops.
I would
like to contest this. The blood group for 59154 was not A; it was “uninterpretable”.
You can see that I’d spotted something awry here as I’ve taken a screen shot of
the picture with which I was presented. Was it a sub-type of A? if so, was
giving A blood wrong?
I think in
this case the software wasn’t quite up to the scenario it was trying to mimic.
But then I would, wouldn’t I?
