I had a go at the BTLP-TACT thingy
today. It presented me with one case – a twenty-nine year-old woman in theatre
having an above-knee amputation and needing two units of blood.
She grouped as O Rh(D) Positive with
antibody screen positive in all three cells. I requested antibody panels.
The IAT panel was positive in cells 1,
2, 3, 5, 6, 7, 9 and 10 corresponding with anti-S and anti-Fy(a) but not
excluding anti-K.
The enzyme panel was negative throughout
which excluded quite a bit..
I selected two units of O Rh(D) Positive
S-negative Fy(a)-negative K-negative
I got the thumbs-down. Apparently there
was a clinically significant antibody masked but not noted. I’d love to know
what it was.
This is a major failing of the BTLP-TACT
simulator. You can’t learn anything from your mistakes.
