A slide agglutination test was developed using latex particles coated with antiserum against the C substance, a common antigen for all serotypes of Streptococcus pneumoniae. This test was used for the rapid identification of pneumococci in blood culture broths which contained Gram positive cocci (GPC) in pairs or short chains on smear examination. Of 238 consecutive blood cultures with GPC tested, 72 were positive for Strep. pneumoniae by the latex test and conventional methods. The remaining 166 cultures were negative for both these, indicating a 100 per cent specificity and sensitivity for the test.
利用包被有抗C物质抗血清的乳胶颗粒开发了一种玻片凝集试验，C物质是肺炎链球菌所有血清型的一种常见抗原。该试验用于快速鉴定血培养肉汤中的肺炎球菌，这些肉汤涂片检查显示成对或短链的革兰氏阳性球菌（GPC）。在连续检测的238份含有GPC的血培养物中，72份通过乳胶试验和传统方法检测肺炎链球菌呈阳性。其余166份培养物这两项检测均为阴性，表明该试验的特异性和敏感性均为100%。
