Measurement of the various amounts of the different types of light chains aids in the diagnosis and monitoring of multiple myeloma, lymphocytic neoplasms, Waldenstrom's macroglobulinemia, amyloidosis, light chain deposition disease and connective tissue diseases such as systemic lupus erythematosus in conjunction with other laboratory and clinical findings. ## Device Story In vitro diagnostic assay for quantitative measurement of kappa and lambda free light chains in human serum; utilizes nephelometry on The Binding Site SPAplus™ analyzer. Input: serum sample; reagent containing polyclonal monospecific sheep antibody coated onto polystyrene latex. Principle: antibody-antigen reaction forms insoluble immune complexes; light scattering measured as signal proportional to antigen concentration. Output: quantitative concentration of free light chains. Used in clinical laboratory settings by trained personnel. Results aid clinicians in diagnosing and monitoring monoclonal gammopathies and related systemic diseases. Prozone detection flags potential antigen excess to prevent falsely low values. ## Clinical Evidence No clinical data provided in the document; the submission relies on bench testing and performance validation for the intended use. ## Technological Characteristics Quantitative nephelometric assay. Reagents: polyclonal monospecific sheep antibody coated on polystyrene latex. Detection: light scattering by immune complexes. Instrument: SPAplus™ analyzer. Matrix: serum. Calibration: multi-point curve using provided calibrators. Software: automated kinetic analysis for prozone detection. ## Regulatory Identification An immunoglobulin (light chain specific) immunological test system is a device that consists of the reagents used to measure by immunochemical techniques both kappa and lambda types of light chain portions of immunoglobulin molecules in serum, other body fluids, and tissues. In some disease states, an excess of light chains are produced by the antibody-forming cells. These free light chains, unassociated with gamma globulin molecules, can be found in a patient's body fluids and tissues. Measurement of the various amounts of the different types of light chains aids in the diagnosis of multiple myeloma (cancer of antibody-forming cells), lymphocytic neoplasms (cancer of lymphoid tissue), Waldenstrom's macroglobulinemia (increased production of large immunoglobulins), and connective tissue diseases such as rheumatoid arthritis or systemic lupus erythematosus. ## 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 Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. 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 Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice {1}------------------------------------------------ Page 2 – Jay H.
