Time for another BTLP-TACT exercise… I
was presented with one case – a seventy-seven year-old woman requiring group
and save.
The control was positive and in the past
that has invalidated the entire group.
The antibody screen was positive in all
three cells so I performed antibody panels.
The IAT panel was positive in all cells
but 4 and 8 which could possibly have been a combination of D, E, Cw, S, Lu(a),
K, Fy(a). However the enzyme screen was negative, so in BTLP-TACT world this
would be a combination of anti-S and anti-Fy(a).
I got it wrong…
The combination of anti-S and anti-Fy(a)
was correct but in BTLP-TACT world apparently anti-K might have been there too.
I’m sure that in the past anti-K has had to work by enzyme in their exercises.
I shall add that to their list of
foibiles…
But apparently anti-Jk(a) could not be
excluded even though panel cell four had a negative reaction despite being
Jk(a) positive.
In layman’s terms, that’s bollox.
