Hi everyone,
Patient is pre-op, never been transfused as far as the bb is aware.
O neg, rr K- phenotype
Negative panel by IAT and enzyme card technique, LISS IAT negative as well. Auto neg.
3 units crossmatched (Oneg rr K-) and performed by IAT card technique = compatible
Saline tube technique at 37, immediate spin = incompatible with 1+ reaction including auto control
I repeated the saline tube with fresh suspension of red cells but got the same reaction.
I thought maybe there's a cold antibody so I also performed a saline panel at room temperature by card and got negative results including neg auto.
Any thoughts?
