Abstract
The performance of StrepB Carrot Broth (SCB) versus group B Lim broth (LIM) for detection of group B streptococcus (GBS) colonization status in near-term pregnant women (35 to 37 weeks of gestation) was evaluated. Dually collected vaginal/rectal swabs from 279 women enrolled from a single large maternity clinic were analyzed. Fifty (18%) women were colonized by GBS according to both methods. SCB had excellent diagnostic performance compared to LIM, with sensitivity, specificity, positive predictive value, and negative predictive value of 92%, 100%, 100%, and 98.3%, respectively. Improved diagnostic efficiency due to direct reporting of GBS cases based on an orange color change in the SCB decreased overall labor and material costs.
摘要
评估了用于检测近期孕妇（妊娠35至37周）B族链球菌（GBS）定植状态的B族链球菌胡萝卜肉汤（SCB）与B组Lim肉汤（LIM）的性能。对从一家大型单一产科诊所招募的279名妇女的阴道/直肠双份拭子进行了分析。根据两种方法，有50名（18%）妇女被GBS定植。与LIM相比，SCB具有出色的诊断性能，敏感性、特异性、阳性预测值和阴性预测值分别为92%、100%、100%和98.3%。基于SCB中橙色变化直接报告GBS病例提高了诊断效率，降低了总体劳动力和材料成本。
