N2 - The BAC-T-SCREEN® (BTS) (Marion Laboratories, Inc., Kansas City, MO) is a 2 1/2 -minute urine screen disigned 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 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 ≥105 CFU/mL were 98.0, 72.2, 57.3, and 99.0%, respectively. These values for specimens containing ≥104 CFU/mL were 93.2, 77.2, 69.2, and 95.5%, respectively.
