The class I HLA types are identified in the mother and at least one of the possible fathers using the conventional lymphocytotoxicity procedure with a large battery of commercially available HLA typing sera that distinguish approximately 20 different HLA-A antigens, 40 different HLA-B antigens, and 8 different HLA-C antigens. These sera are obtained from women who have been immunized through pregnancy against the paternal HLA antigens of their own fetus.
