Urinary tract infection is a common disease diagnosed from symptoms and clinical signs, and bacterial count per volume of urine. This study have evaluated the BiesseBioscreen analyzer as a new way to analyze urine samples en- abling fast screening of urine, prior to reference standard methods currently utilized in microbiology analysis labo- ratory. We analyzed 962 urine samples from outpatients and inpatients of the Tor Vergata (TV) University Hospital of the University of Rome "Tor Vergata". All samples were processed both with the BiesseBioscreen and with the standard methodology adopted by the clinical microbiology laboratory of TV Hospital and the results were com- pared. Of the samples analyzed 54.9% were concordant negative with the reference method and 21.6% concordant positive, 23.3% resulted false positive and 0.2% false negative. The results obtained from BiesseBioscreen showed a sensitivity of 99.0%, indicating it as a system suitable to rule out urinary tract infection. BiesseBioscreen could represent a valid method for screening negative samples to exclude from culture test with a potential reduction in time, workload and costs of the diagnosis
