The quantex Ferritin controls I/I are intended for use in monitoring the quality control of results obtained with the quantex Ferritin reagents by turbidimetry. The quantex Ferritin standard multipoint is intended for use in establishing the calibration curve for the quantex Ferritin reagents by turbidimetry. ## Device Story Quantex Ferritin is a latex particle-enhanced immunoturbidimetric assay; measures ferritin levels in human serum or EDTA plasma samples. Operates on clinical chemistry systems; utilizes turbidimetry to quantify ferritin concentration. Provides quantitative results to clinicians; aids in diagnosing iron metabolism diseases like hemochromatosis and iron deficiency anemia. Includes dedicated controls and multipoint standards for calibration and quality monitoring. Used in clinical laboratory settings by trained personnel. ## Clinical Evidence No clinical studies performed. Evidence consists of analytical bench testing: precision (n=60, total CV 2.29-12.3%), linearity (R² 0.999-1.000), and method comparison (n=94, slope 0.9293). Interference testing confirmed minimal impact from lipemia, RF, bilirubin, and hemoglobin. ## Technological Characteristics Latex particle-enhanced immunoturbidimetric assay. Reagents: Ferritin R1 (buffer) and R2 (rabbit IgG anti-ferritin coated polystyrene latex). Calibrators: TRIS buffer with human ferritin. Controls: Lyophilized human ferritin. Connectivity: ILAB 900/1800 clinical chemistry systems. Traceability: 3rd WHO International Standard (NIBSC 94/572). ## Regulatory Identification A ferritin immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the ferritin (an iron-storing protein) in serum and other body fluids. Measurements of ferritin aid in the diagnosis of diseases affecting iron metabolism, such as hemochromatosis (iron overload) and iron deficiency amemia. ## Predicate Devices - AxSYM Ferritin ([K935847](/device/K935847.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The quantex Ferritin controls I/I are intended for use in monitoring the quality control of results obtained with the quantex Ferritin reagents by turbidimetry. The quantex Ferritin standard multipoint is intended for use in establishing the calibration curve for the quantex Ferritin reagents by turbidimetry. ### Statement of Technological Characteristics of the Device Compared to Predicate Device: Quantex Ferritin is substantially equivalent to the commercially available predicate device, AxSYM Ferritin, in performance and intended use. #### Summary of Performance Data: In a method comparison study evaluating 94 serum samples with Ferritin levels ranging from 3.2 to 1000 ng/ml on an ILab 900/1800, the slope was 0.92 and the correlation coefficient (r) was 0.994 for quantex Ferritin versus the predicate device. Within precision assessed over multiple runs using quantex Ferritin controls VII on an Lab 900/1800 gave a CV of 4.1% (at a mean of 43.2 ng/mL) and 1.6% (at a mean of 402.8 ng/mL). {1}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/1/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
