Improving the diagnosis of urinary tract infections by the use of enriched media and a 48-hour incubation period.

The absence of a gold-standard methodology for the microbiological diagnosis of urinary tract infections (UTI) has led to insufficient standardization of criteria for the interpretation of results and processing methods, particularly incubation time and culture media. 48-hour incubation time period and use of blood agar enhances the sensitivity of microorganisms isolated significantly. To determine the sensitivity of blood agar and Brilliance UTI chromogenic agar, incubating for different periods (24-48 hours), for the detection of positive urine cultures.
