The BACTEC 9240 blood culture system with a standard aerobic medium, Plus Aerobic/F, was compared to the BacT/Alert system with a platelet-specific medium, BPA, as a means for detecting bacterial contamination of platelet preparations. One hundred thirteen platelet units seeded with low levels of different bacteria were examined with both systems. In 93 instances, growth was detected first in the BACTEC system; in 12 cases, growth registered first in the BacT/Alert system. Among all comparisons, growth was detected, on average, 1.7 h sooner with the BACTEC system. The differences in length of time to detection were statistically significant.
将配备标准需氧培养基（Plus Aerobic/F）的BACTEC 9240血培养系统与配备血小板特异性培养基（BPA）的BacT/Alert系统进行比较，以此作为检测血小板制剂细菌污染的一种方法。用这两种系统检测了接种低水平不同细菌的113个血小板单位。在93例中，BACTEC系统首先检测到生长；在12例中，BacT/Alert系统首先记录到生长。在所有比较中，BACTEC系统平均比其他系统早1.7小时检测到生长。检测时间长度的差异具有统计学意义。
