21 July 2025 (Monday) - Getting the BTLP-TACT Wrong

 Time for a BTLP-TACT exercise. I was presented with two scenarios:

 

47434 – an eighty year old woman who has had a CVA requiring group and save.

She grouped as O Rh(D) Positive with a negative antibody screen.

 

98077 – a twenty-two year old woman in A&E requiring six units of blood having received gun shot wounds.

She grouped as A Rh(D) Positive with antibody screen positive in all three cells. Just what you want in a case like this, eh? I requested antibody panels.

 

The IAT panel was positive in cells 1, 2, 3, 5, 6, 7, 9 and 10 corresponding with anti-K and anti-Fy(a) but not excluding anti-Cw or anti-Lu(a)

The enzyme panel was negative throughout… that was a pain. In this simulator it thinks anti-K works by enzyme… doesn’t it?

I selected six units of A Rh(D) Positive K-negative Fy(a)-negative.

 

I got the thumbs-down. I missed a possible anti-S
