The iChem® VELOCITY™ automated urine chemistry system is an in vitro diagnostic device used to automate the urine chemistry analysis profile using iChem® VELOCITY ™ Urine Chemistry Strips. The iChemVELOCITY can be used as a stand-alone system, as well as in an iQ®200 Series system, a configuration given the proprietary name iRICELL™ as it is designed to be hardware and software compatible with iQ200 Series systems. It produces quantitative results for specific gravity; semi-quantitative results for glucose, blood, leukocyte esterase, bilirubin, urobilingen, pH, protein, ketones and ascorbic acid; and qualitative results for nitrites, color and clarity. iChemVELOCITY strips are intended for use only with the iChem Velocity analyzer. In particular, they are not intended for visual reading. The iChemVELOCITY is not intended to be used as a Point of Care (POC) analyzer. These measurements are used to aid in the diagnosis of metabolic disorders, kidney function anomalies, urinary tract infections, and liver function. Tests performed using the iChemVELOCITY are intended for clinical laboratory and in vitro diagnostic use only.

The iChemVELOCITY is an automated urine chemistry system performing measurements of defined physical and chemical constituents in urine. The system utilizes iChemVELOCITY urine chemistry test strips which are read in the Strip Reader Module (SRM) by measuring light reflectance, in addition the iChemVELOCITY measures color and clarity using light transmittance through Color/Clarity Module (CCM) and specific gravity using refractive index through Specific Gravity Module (SGM). The subject of this submission is a design change to the Color/Clarity Module (CCM) of the Color/Clarity/Specific Gravity Module (CGM) subassembly of the iChemVELOCITY. The CCM measures the color and clarity of a urine sample using transmitted and scattered light, incident on a color sensor. An algorithm then converts the output of the different channels of the sensor into semi-quantitative colors. The CCM is being changed to replace end-of-life components (color sensor and scatter light source) and update the color detection algorithm.
