When a complement-dependent cytotoxicity test was performed using standard antibodies to HLA A1,A3,B2,and B11,the following microscopic results were obtained: a majority of blue cells were seen with anti-A1,A3,and B11.Based on these results,what is the phenotype of the donor cells?

The presence of blue cells with standard antibodies to HLA A1, A3, and B11 indicates the presence of these antigens on the donor cells. The lack of blue cells with anti-B2 antibodies suggests the absence of this antigen. Therefore, the donor cells are likely of the HLA A1, A3, B11 phenotype.
