Hi everyone!
I have an OB patient (first semester of pregnancy) who has a history of A positive, 3 previous pregnancies, who is puzzling me and I would appreciate your input. My results are:
In gel,
Anti-A 4+
Anti-B 0
Anti-D 4+
Ctl 0
A1 cells IS (no RT inc.) w+, 15 min RT inc. 3+
A2 cells 0
B cells 4+
In tube, I have a weak A1 microscopic (and no rouleaux). A1 lectin is negative (weak pos micro, which the package insert says that a weak pos should be considered negative).
Antibody screen negative at 37 C and RT. I ruled out P1 and M with gel.
Is the patient really A with anti-A1 IGM? I am just concerned because she is pregnant, I want to make sure that there is not something I am forgetting...
Thanks in advance,
Helen
