31 October 2025 (Friday) - BTLP-TACT Exercise

I’ve done six separate BTLP-TACT exercises (ten individual cases) this month and *still* I’m getting emails saying “you may need to complete further TACT participations to improve your engagement target with the system”. So I logged in again…
I was presented with two more cases:
 

51898 – an eighty-nine year old chap with beta thalassaemia needing two units of blood

He grouped as A Rh(D) Positive with a negative antibody screen. I selected two units of A Rh(D) Positive blood.

 

54334 – a twenty-six year old woman needing two units of irradiated blood prior to a stem cell transplant. She grouped as O Rh(D) Positive, but with a weak D reaction. In this world that counts as indeterminate.

The antibody screen was positive in cell 2 so I performed antibody panels.

The IAT panel was positive in cells 2, 3, 5 and 6 corresponding to anti-E and anti-K

The enzyme panel was strongly positive in cells 3 and 5 corresponding with anti-E, and it was weaker with cells 2 and 6 corresponding with anti-K. I selected two units of O Rh(D) Negative K-Neg E-Neg irradiated blood

 
I got it right…
