Abstract
The FiltraCheck-UT1 (FC) is a disposable colorimetric urine screen for bacteriuria that requires less than 1 min to perform. The results of the FC and two other urine screens, the Bac-T-Screen (BTS) and the Chemstrip LN test strip (LN), were compared with quantitative culture method. A total of 551 urine specimens were tested. The sensitivity of FC, BTS, and LN for probable pathogens at greater than or equal to 10(5) CFU/ml was 94.8%, 97.4%, and 77.9% respectively. These values for specimens with probable pathogens at greater than or equal to 10(4) CFU/ml were 91.1%, 92.1%, and 74.3%, respectively. When the LN was combined with the FC or BTS as a urine screen, the sensitivity for probable pathogens was improved.
