Background: The novel urine chemistry analyzer iChem Velocity (IRIS Diagnostics) offers improved urinalysis automation options through integration with the well-established iQ200 urine microscopy analyzer. In the course of optimizing the workflow in our hospital routine laboratory, we evaluated the performance of the iChem Velocity.

Methods: A total of 257 random urine samples were analyzed with the iChem Velocity, iQ200, Clinitek Atlas (Siemens Healthcare Diagnostics) and by manual microscopy.

Results: Depending on the parameter, 93% (hemoglobin) to 100% (urobilinogen), the iChem Velocity and Clinitek Atlas results agreed within the same rank or within one level of difference. The Clinitek Atlas featured a higher sensitivity for hemoglobin (area under the curve 0.86) and leukocyte esterase (area under the curve 0.85) compared with the iChem Velocity (area under the curve for hemoglobin...
