Monoclonal reagents of IgM type now allow to test some red blood cell antigens (K; Jk a; Jk b) by the tube centrifugation method at room temperature for which an indirect antiglobulin test was necessary before. This enables to test antigens also when the direct antiglobulin test is positive, provided that there are no disturbances by supplements contained in the sera. We examined monoclonal blood group sera of different manufacturers for their ability to test antibody-coated erythrocytes; sometimes we found great differences between the different products. Therefore we recommend to add this test to the other criteria of quality control, especially when it is necessary to test antigens in patients with positive direct antiglobulin test.
IgM型单克隆试剂现在允许在室温下通过试管离心法检测一些红细胞抗原（K；Jk a；Jk b），而此前检测这些抗原需要进行间接抗球蛋白试验。这使得即使直接抗球蛋白试验呈阳性时也能检测抗原，前提是血清中所含的补体没有干扰。我们检查了不同厂家的单克隆血型血清检测抗体包被红细胞的能力；有时我们发现不同产品之间存在很大差异。因此，我们建议将此检测纳入其他质量控制标准，尤其是在有必要检测直接抗球蛋白试验阳性患者的抗原时。
