Therefore, a rapid, reliable screening method is necessary to speed up the reporting of a negative result. In this study, we evaluated the iQ200/iChem workstation, which is a combination of digital imaging software and a strip reader to predict negative urine culture.<h4>Method</h4>A total of 1942 urine specimens were processed through both culture and iQ200/ iChem workstation. We analyzed the performance using two definition of positive urine culture; one or two potential uropathogens at a concentration of ≥10⁵ CFU/ml and ≥ 10⁴ CFU/ml. We assessed combinations of parameters (ASP; all small particles, WBC; leukoBMC infectious diseasesClinical usefulness of iQ200/iChem Velocity workstation for screening of urine culture.PMC6580579HI16C0443Baek DJPark KGPark YJLee JMHan EfalseClinical usefulness of iQ200/iChem Velocity workstation for screening of urine culture.<h4>Background</h4>Clinical microbiology laboratories are asked to process large numbers of urine specimens for culture, but only 20-40% of them are positive.
