Abstract
Seven automated bacteriuria screening methods are currently available for clinical use. Three are based on the principle of photometry: the Autobac Systema, the AutoMicrobic Systemb, and the MS-2c. Three utilize bioluminescence: the Lumacd, Monolight 2001e, and Turner Luminometerf. One method is based on colorimetry and filtration: Bac-T-Screeng. Detection times for these systems range from two minutes to nine hours. This article reviews these systems with regard to sensitivity, predictive value, detection time, and cost.
