[Incompatible xm]

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?
