Measurements of ferritin aid in the diagnosis of diseases affecting iron overload and iron deficiency anemia. For in vitro diagnostic use. The K-ASSAY® Ferritin Calibrator Set is an in vitro diagnostic reagent for calibration of the K-ASSAY® Ferritin (2) Assay. For in vitro diagnostic use. ## Device Story K-ASSAY® Ferritin (2) is an in vitro diagnostic reagent kit for quantitative ferritin measurement in human serum/plasma. Input: patient serum or plasma samples. Principle: latex-enhanced immunoturbidimetric assay; sample mixed with reagent containing latex particles sensitized with rabbit anti-human ferritin antibody; agglutination occurs proportional to ferritin concentration. Output: absorbance change measured via turbidimetry on Roche/Hitachi 917 analyzer; concentration determined by interpolation from a calibration curve. Used in clinical laboratories by trained personnel. Output aids clinicians in diagnosing iron overload and iron deficiency anemia, potentially benefiting patients through timely identification of iron-related disorders. ## Clinical Evidence No clinical prospective or retrospective studies provided. Performance supported by bench testing: precision (CV < 7%), linearity (R ≥ 0.99, range 2-1000 ng/mL), and analytical specificity (no interference from hemoglobin, bilirubin, lipids, or rheumatoid factor). Method comparison with predicate (n=64) showed correlation coefficient R=0.9969, slope 0.89. Matrix comparison (n=20) confirmed equivalence between serum, EDTA, and sodium heparin plasma. ## Technological Characteristics Latex-enhanced immunoturbidimetric assay. Reagents: reaction buffer and latex particles coated with rabbit anti-human ferritin antibodies. Instrument: Roche/Hitachi 917 analyzer. Calibration: 5-point curve using liquid calibrators. Traceability: 1st WHO International reference Preparation Human Ferritin (BIBSC 80/602). ## 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. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Parl 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. {1}------------------------------------------------ Page 2 - If you desire specific information about the application of labeling requirements to your device, or questions on the promotion and advertising of your device, please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (240) 276-0484.
