Identification of urinary protein is used in the diagnosis and treatment of disease conditions such as renal or heart diseases or thyroid disorders, which are characterized by proteinuria or albuminuria. CSF protein measurements are used in the diagnosis and treatment of conditions such as meningitis, brain tumors, and infections of the central nervous system. ## Device Story In vitro diagnostic assay for quantitative protein measurement in human urine or CSF. Uses turbidimetric procedure with benzethonium chloride as denaturing agent; forms fine suspension measured at 405 nm. Modified reagent prevents high-concentration (Hook) effect. Operated on ALCYON™ Analyzer in clinical laboratory settings by trained personnel. Output is quantitative protein concentration (mg/dL). Results assist clinicians in diagnosing and monitoring renal, cardiac, thyroid, and CNS disorders. Benefits include rapid, automated assessment of protein levels to guide clinical decision-making. ## Clinical Evidence Bench testing only.

The assigned 510(k) number is: K981295 ### Test Description: Urine/CSF Protein is an in vitro diagnostic assay for the quantitative determination of protein in human urine or cerebrospinal fluid (CSF) on the ALCYON™ Analyzer. The Urine/CSF Protein assay is a clinical chemistry assay using a turbidimetric procedure in which benzethonium chloride is used as the protein denaturing agent. Proteins present in the urine or CSF are denatured by benzethonium chloride resulting in the formation of a fine suspension which is quantitated turbidimetrically at 405 mm. The reagent has been modified to overcome the problem of high concentration (Hook) effect, where very high concentrations of protein in urine can cause an apparent zero or low reading. Urine/CSF Protein 510(k) September 29, 1998 MicroproteinFinal3.lwp Section II Page 1 ្រ {1}------------------------------------------------ #### Substantial Equivalence: The Urine/CSF Protein assay is substantially equivalent to the Boehringer Mannheim® Urinary/CSF Protein assay on the Hitachi® 717 Analyzer (K913615). Both assays yield similar Performance Characteristics. Similarities: - . Both assays are in vitro clinical chemistry methods. - . Both assays can be used for the quantitative determination of protein in urine or cerebrospinal fluid. - . Both assays yield similar clinical results. #### Intended Use: The Urine/CSF Protein assay is used for the quantitative determination of protein in human urine or cerebrospinal fluid (CSF). #### Performance Characteristics: Comparative performance studies were conducted using the ALCYON™ Analyzer. The Urine/CSF Protein assay method comparison yielded acceptable correlation with the Boehringer Mannheim Urinary/CSF Protein assay on the Hitachi 717 Analyzer. For the urine application, the correlation coefficient = 0.995, slope = 0.943, and Y-intercept = 5.146 mg/dL. For the CSF application, the correlation coefficient = 0.981, slope = 0.995, and Y-intercept = 1.184 mg/dL. Precision studies were conducted using the Urine/CSF Protein assay. Within-run, between-run, and between-day studies were performed using two levels of control material. The total %CV for Level 1/Panel 131 is 5.1% and Level 2/Panel 132 is 4.5% for the urine application. The total %CV for Level 1/Panel 601 is 2.6% and Level 2/Panel 602 is 2.1% for the CSF application. The Urine/CSF Protein assay is linear from 10 to 200 mg/dL. The limit of quantitation (sensitivity) for the Urine/CSF Protein assay is 10 mg/dL. The functional sensitivity was based on the lowest calibrator (standard) value used in the determination of the Urine/CSF Protein Linearity (standards ranged Urine/CSF Protein 510(k) September 29, 1998 MicroproteinFinal3.1wp Section II Page 2 {2}------------------------------------------------ ته الله ته الله " from 10 to 200 mg/dL). These data demonstrate that the performance of the Urine/CSF Protein assay is substantially equivalent to the performance of the Boehringer Mannheim Urinary/CSF Protein assay on the Hitachi 717 Analyzer. ## Conclusion: The Urine/CSF Protein assay is substantially equivalent to the Boehringer Mannheim Urinary/CSF Protein assay on the Hitachi 717 Analyzer as demonstrated by results obtained in the studies.
