摘要
本研究对两瓶非放射性血液培养系统(BACTEC NR 660)的灵敏度、准确性和实用性进行了评估，并与我们实验室使用的两瓶常规血液培养系统进行了比较。在20周的时间内，共采集成人4个血培养瓶592份，阳性126份。传统体系分离出121株，BACTEC NR 660体系分离出97株。两组康复率差异无统计学意义。在常规系统中检测到的污染物分离物频率更高(p < 0.001)。在一个或两个BACTEC NR 660瓶中，微生物的回收率比在常规系统中更快(p < 0.001)。本研究证实BACTEC NR 660系统适用于菌血症的常规检测。
Clinical evaluation of non-radiometric BACTEC NR 660 system for routine detection of bacteremia.
A study was undertaken to evaluate the sensitivity, accuracy and practicability to a two-bottle nonradiometric blood culture system (BACTEC NR 660) with the two bottle conventional blood culture system in use in our laboratory. A total of 592 sets of four blood culture bottles were collected from adults in a twenty-week period, giving 126 positive sets. The conventional system recovered 121 isolates, whereas the BACTEC NR 660 system recovered 97 microorganism. The difference in the recovery rate was not statistically significant. Contaminant isolates were detected with greater frequency in the conventional system (p less than 0.001). Microorganism were recovered faster in one or both BACTEC NR 660 bottles than in conventional system (p less than 0.001). Our study confirms that BACTEC NR 660 system is suitable for routine detection of bacteremia.
