In this study, 801 pharyngeal specimens were cultured for group A streptococci and tested with the Biostar Strep A Optical Immunoassay (Strep A OIA). The respective sensitivities and specificities were as follows: culture, 97.1 and 100%; Strep A OIA, 91.5 and 94.8%. Of the 801 specimens, 597 were also tested with the Abbott TestPack Strep A Assay (TP-ST). For those specimens tested by all three methods, the respective sensitivities and specificities were as follows: culture, 98.1 and 100%; Strep A OIA, 92.3 and 95.4%; and TP-ST, 79.4 and 100%. The Strep A OIA is significantly more sensitive than TP-ST and compares favorably with culture.
在本研究中,对801份咽拭子标本进行了A组链球菌培养,并采用Biostar A群链球菌光学免疫测定法(A群链球菌OIA)进行检测。各自的敏感性和特异性如下:培养法,97.1%和100%;A群链球菌OIA,91.5%和94.8%。在801份标本中,有597份还采用雅培A群链球菌检测试剂盒(TP-ST)进行了检测。对于所有三种方法都检测的那些标本,各自的敏感性和特异性如下:培养法,98.1%和100%;A群链球菌OIA,92.3%和95.4%;TP-ST,79.4%和100%。A群链球菌OIA比TP-ST明显更敏感,与培养法相比也具有优势。
