I suppose I should really do a BTLP-TACT
exercise…
I had one case – a seventy year old woman
supposedly needing FFP for reversal of warfarin therapy.
Her ABO group was indeterminate (cell
group A, no reaction in reverse group) but her Rh(D) group was negative.
The antibody screen was weakly positive
in cells 1 and 2 so I performed antibody panels.
The IAT and enzyme panels were positive
in cells 1, 2 and 3 corresponding with anti-D but not excluding anti-Cw.
Bearing in mind warfarin
isn’t recommended for the reversal of warfarin therapy, I didn’t issue any.
I got it right this time…
