For some time, anomalous serological reactions have been observed when the same anti-Swa sera are tested against red cells from different individuals reported as Sw(a+). A comparative collaborative study using the same collection of Sw(a+) cells and anti-Swa sera was undertaken by 4 reference laboratories, and it was found that Swa represents a heterogeneous group of antigens that can be subdivided into two categories. Both categories, Sw(a+) 700:41 and Sw(a+) 700:-41, were shown to be inherited.
一段时间以来，当用相同的抗-Swa血清检测来自不同个体报告为Sw(a+)的红细胞时，观察到异常的血清学反应。4个参考实验室对相同的Sw(a+)细胞和抗-Swa血清样本进行了一项比较协作研究，发现Swa代表一组异质性抗原，可细分为两类。这两类，即Sw(a+) 700:41和Sw(a+) 700:-41，均显示为可遗传的。
