The Gen-Probe Group A Streptococcus Direct Test (GP-ST) is a new assay which utilizes a nucleic acid probe to detect group A streptococci directly from pharyngeal swabs. In this study, 1,103 specimens were cultured and tested by GP-ST. The sensitivities and specificities were as follows: culture, 98.8 and 100%; GP-ST, 92.4 and 99.6%. Of the 1,103 specimens, 808 were also tested with the TestPack Strep A assay. For the specimens tested by all three methods, the sensitivities and specificities were as follows: culture, 99.5 and 100%; TestPack Strep A assay, 76.3 and 99.7%; GP-ST, 93.5 and 99.7%. The GP-ST is a very user-friendly assay which has the potential to replace culture for the diagnosis of streptococcal pharyngitis.
基因探针A群链球菌直接检测试验(GP - ST)是一种新的检测方法,它利用核酸探针直接从咽拭子中检测A群链球菌。在本研究中,对1103份标本进行了培养并用GP - ST检测。敏感性和特异性如下:培养法,98.8%和100%;GP - ST,92.4%和99.6%。在1103份标本中,808份还采用了A群链球菌快速检测试剂盒进行检测。对于用所有三种方法检测的标本,敏感性和特异性如下:培养法,99.5%和100%;A群链球菌快速检测试剂盒,76.3%和99.7%;GP - ST,93.5%和99.7%。GP - ST是一种非常便于使用的检测方法,有潜力取代培养法用于链球菌性咽炎的诊断。
