A subgroup of patients with rheumatoid arthritis (RA) whose sera agglutinated sensitized sheep erythrocytes used for total hemolytic complement determination has been identified. These patients have higher titers of rheumatoid factor (RF) and more severe rheumatoid disease compared to controls. The agglutination of sensitized sheep erythrocytes by sera of some patients with RA may be related to qualitative or quantitative variations in their RF.
已识别出一组类风湿性关节炎（RA）患者，其血清可凝集用于总溶血补体测定的致敏绵羊红细胞。与对照组相比，这些患者的类风湿因子（RF）滴度更高，类风湿疾病更严重。一些RA患者血清对致敏绵羊红细胞的凝集可能与其RF的质量或数量变化有关。
