A novel color test for the rapid detection of group A streptococci has been developed. The test, designed to be suitable for use in clinical laboratories as well as by less experienced personnel, incorporates the simplicity of latex tests with a color change to indicate the presence of group A streptococcal antigen. The test, which takes 5 min, was evaluated with 646 throat swabs, with a 15.6% incidence of group A streptococci; for swabs which yielded 10 or more group A streptococcal colonies in cultures, the sensitivity was 96.8%, and the specificity was 99.1%. In addition, the color test was 100% sensitive and specific when used to detect group A streptococcal antigen in beta-hemolytic colonies from culture plates.
已开发出一种用于快速检测A群链球菌的新型颜色试验。该试验设计得既适合临床实验室使用，也适合经验较少的人员使用，它结合了乳胶试验的简便性，并通过颜色变化来指示A群链球菌抗原的存在。该试验耗时5分钟，用646份咽拭子进行了评估，A群链球菌的发生率为15.6%；对于培养物中产生10个或更多A群链球菌菌落的咽拭子，敏感性为96.8%，特异性为99.1%。此外，当用于检测培养平板上β溶血菌落中的A群链球菌抗原时，颜色试验的敏感性和特异性均为100%。
