[Question about A subgroup]

Okay.

 

Why are we giving A type units? Can't an A₂ subtype form an allogeneic anti-A_1?  If so, should we continue to transfuse the patient with A type blood until they develop an antibody? 

[Question about A subgroup]

Hi, think this is my first post here. My name is Amy, just to share a tidbit with everyone.. 

 

I had a patient today that typed as such:

 

Forward type:

Anti-A = 2+

Anti-B = 4+

Anti-D = 4+

 

Reverse type:

Acell = 0

Bcell = 0

 

Anti-A1 = 0

 

87 y/o male, oncology patient. 

 

I was reviewing reports for the BB Supervisor, when I saw the weak Anti-A in forward, I investigated and got the aforementioned results.

The overnight tech released A+ blood on this patient, but no symptoms of transfusion reaction.

I notified my pathologist and switched the patient to O+ in light of the absence of A1 antigens.

 

my question:

I am surprised to see that the A cell in the reverse type is coming up negative. In my texbook, type discrepancies such as this are accompanied by the presence of anti-A1 in the patient's plasma. Here, I don't have a demostrable Anti-A1 and I am wondering if the antibody is naturally occuring, and in what frequency?
