During an antibody ID, there was 1+ reaction at AHG with donor cells with the antigen profile Fya(+), Fyb(-). All other donor cells on the panel were negative, including those that were Fya(+), Fyb(+). Given these results, what might be the conclusion?
A) Single antibody (showing dosage)
B) Probably an antibody not represented on the antigen profile
C) An antibody to a high-frequency antigen
D) IgM antibody

The reaction pattern suggests a single antibody showing dosage, as it reacts with Fya(+) Fyb(-) cells but not with Fya(+) Fyb(+) cells, indicating sensitivity to antigen density.
