21 April 2024 (Sunday) - Failing the BTLP-TACT Again

Time for another BTLP-TACT exercise. I was given two cases:
 
18673 – a ninety-three year-old woman in out patients requiring group & save
 
She grouped as O Rh(D) Positive with a negative antibody screen
 
14253 – a forty-two year-old woman needing two units of blood for tomorrow
 
The control being positive invalidates the entire group
 
The antibody screen was positive in cell 1. I performed antibody panels.
The IAT and enzyme panels were positive in cells 2, 4, 5, 8, 9 and 10
This looks like anti Jk(b) but doesn’t exclude Lu(a) or Kp(a)
Bearing in mind there was no suitable blood available I was bound to get a red light…
 
What was I supposed to do?
