Two high frequency antigens, Hy (Holley) and Gy-a (Gregory), show an apparent association. All individuals lacking Gy-a are whites and these individuals are Hy-negative. A second group of Hy-negative individuals are blacks. All of these react weakly with anti-Gy-a. Neither Gy-a nor Hy are well developed on cord cells, although antibodies to both factors have been stimulated by pregnancy. Anti-Gy-a and anti-Hy antibodies react best in the antihuman globulin test. These antibodies have low avidity, high titers, and have been implicated as causing transfusion reactions.
两种高频抗原，Hy（霍利）和Gy-a（格雷戈里），表现出明显的关联。所有缺乏Gy-a的个体均为白人，且这些个体为Hy阴性。另一组Hy阴性个体为黑人。所有这些个体与抗Gy-a反应较弱。Gy-a和Hy在脐血细胞上均发育不良，尽管两种因子的抗体已因妊娠而被激发。抗Gy-a和抗Hy抗体在抗人球蛋白试验中反应最佳。这些抗体亲和力低、效价高，并被认为可导致输血反应。
