Hi guys,

I am new to the Hem/BB supervisory role and have a question.  A year ago a patient of ours was sent to the reference lab and came back as a warm auto and we were told to honor E, C, and K.  Now this patient has a new specimen and the antibody screen was negative on the Provue gel testing.  Do these patients once they have a warm auto always need further testing or if we get a negative antibody screen, can we go to crossmatches on E, C, and K negative units? 

thanks

Were you told to honor E, C & K because the patient was found to have alloantibodies to them or just because the patient lacks the antigens?

We were told to honor E,C, & K because the patient lacks the antigens.  He doesn't have any known alloantibodies at this time.

No additional testing required. We would electronic crossmatch this patient with random units

Dansket, is "warm autoantibody" not set up as clinically significant in your LIS?

We would do the same.

No further testing but honor antigens patient is lacking.

No further testing but give C-,E-,K- extended crossmatch compatible units.
