A glucose-specific test paper which is sufficiently sensitive to react with the small amounts of glucose present in urine from normal persons in the fasting state can be used to discriminate between urine samples containing more than and those containing less than 1 to 1.5 mg of glucose per 100 ml of urine. This provides a screening method for significant bacteriuria in an apparently healthy population since urine samples, obtained under standardized conditions from subjects in the fasting state with such bacteriuria, contain either very little or no glucose.
