A comparison of the direct agglutination test and the indirect hemagglutination test for the detection of blood serum antibodies to Escherichia coli organisms indicated that these serological tests were comparable. In some instances the indirect hemagglutination test provided higher endpoint readings. Preparation of the antigens for the indirect hemagglutination test was more time consuming than for the direct agglutination test. Crude extract and purified polysaccharides were comparable as red blood cell sensitizing agents.
一项关于直接凝集试验和间接血凝试验用于检测血清中抗大肠杆菌抗体的比较表明，这些血清学试验具有可比性。在某些情况下，间接血凝试验的终点读数更高。间接血凝试验抗原的制备比直接凝集试验更耗时。粗提物和纯化多糖作为红细胞致敏剂具有可比性。
