The Lyra Direct strep assay was compared to culture for its ability to detect Streptococcus group A and β-hemolytic groups C/G using rapid antigen-negative pharyngeal specimens (n = 161). The Lyra assay correctly detected all β-hemolytic streptococci (group A, n = 19; group C/G, n = 5). In batch mode, the Lyra assay reduced intralaboratory turnaround time by 60% (18.1 h versus 45.0 h) but increased hands-on time by 96% (3 min 16 s versus 1 min 40 s per specimen).
将Lyra直接链球菌检测法与培养法进行比较,以评估其使用快速抗原阴性咽拭子标本(n = 161)检测A组链球菌和C/G组β溶血性链球菌的能力。Lyra检测法正确检测出了所有β溶血性链球菌(A组,n = 19;C/G组,n = 5)。在批量模式下,Lyra检测法将实验室内部周转时间缩短了60%(从45.0小时降至18.1小时),但每个标本的实际操作时间增加了96%(从1分40秒增至3分16秒)。
