We used the anti-A、anti-B、anti-A1、 anti-H、A1 、A2、B and screen cell of immucor company. Anti-A is gamma clone. I had used another manufacturer's anti-A and A1 、A2 cell. The result is same. Anti-H reagent with A1 、A2 control cells result (A1=neg , A2 =2+) I agree with Ginal. Plasma from A(sub)B may occasionally contain weak anti-A1,so it can react with A1 cell. why serum from the donor agglutinate both A1 and A2 cell. I am confused My English is not good. Am I understood?
