Abstract

The BAC-T-SCREEN (BTS) (Marion Laboratories, Inc., Kansas City, MO) is a 2 1/2-minute urine screen designed to detect culture-negative specimens. A total of 1,609 urine specimens were tested by the BTS, and results were compared with quantitative culture methods. One hundred and forty-eight (9.2%) specimens were not screened successfully by the BTS because they contained interfering pigments or clogged the test filters. A total of 1,461 specimens were tested successfully. The sensitivity, specificity, positive predictive value, and negative predictive value for specimens containing greater than or equal to 10(5) CFU/mL were 98.0, 72.2, 57.3, and 99.0%, respectively. These values for specimens containing greater than or equal to 10(4) CFU/mL were 93.2, 77.2, 69.2, and 95.5%, respectively.

摘要

BAC-T-SCREEN（BTS）（马里恩实验室公司，密苏里州堪萨斯城）是一种耗时2分半钟的尿液筛查方法，旨在检测培养阴性的标本。共对1609份尿液标本进行了BTS检测，并将结果与定量培养方法进行了比较。148份（9.2%）标本因含有干扰色素或堵塞测试滤器而未被BTS成功筛查。共1461份标本检测成功。对于菌落形成单位（CFU）/毫升大于或等于10⁵的标本，其灵敏度、特异性、阳性预测值和阴性预测值分别为98.0%、72.2%、57.3%和99.0%。对于CFU/毫升大于或等于10⁴的标本，这些值分别为93.2%、77.2%、69.2%和95.5%。
