No
The summary describes a standard immunoturbidimetric assay for measuring protein concentrations, which is a well-established laboratory technique that does not typically involve AI/ML. There are no mentions of AI, ML, image processing, or any other indicators of AI/ML technology.
No
The device is described as an in-vitro diagnostic assay used for the quantitative determination of Kappa/Lambda Free Light Chain concentration to aid in the diagnosis of multiple myeloma, not for treatment.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the assays "aid in the diagnosis of multiple myeloma," which clearly indicates a diagnostic purpose.
No
The device description clearly indicates it is a "latex particle enhanced immunoturbidimetric assay" for measuring substances in serum. This describes a laboratory test kit and associated reagents, which are physical components, not software.
Yes, based on the provided text, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The text explicitly states "For in-vitro diagnostic use only" for both assays.
- Intended Use: The intended use describes the quantitative determination of substances (Kappa and Lambda Free Light Chains) in a biological sample (serum) to aid in the diagnosis of a disease (multiple myeloma). This is a core function of an in vitro diagnostic device.
- Methodology: The description of the assay as a "latex particle enhanced immunoturbidimetric assay" indicates a laboratory-based test performed on a biological sample outside of the body.
Therefore, the provided information clearly identifies this device as an In Vitro Diagnostic.

§ 866.5550 Immunoglobulin (light chain specific) immunological test system.
(a)
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.(b)
Classification. Class II (performance standards).

Dear Abhijit Datta:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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 Part 807); labeling (21 CFR Part
1
801 and Part 809); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.
