The summary describes a standard immunoassay system for measuring vitamin B12. There is no mention of AI, ML, or any computational methods beyond standard data processing for quantitative measurement.
No
The device is an in vitro diagnostic (IVD) product that measures vitamin B12 levels to aid in the diagnosis of anemia, not directly treat it.
Yes
The intended use states that the device is "to aid in the differential diagnosis of anemia," which directly indicates a diagnostic purpose.
No
The device description explicitly states it is comprised of reagent packs, calibrators, and instrumentation, which are all hardware components used in an in vitro diagnostic system.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states "for the in vitro quantitative measurement of vitamin B12 in human serum and plasma... to aid in the differential diagnosis of anemia." This clearly indicates the device is used to test samples taken from the human body outside of the body (in vitro) for diagnostic purposes.
- Device Description: The description details a system that uses reagents and instrumentation to perform quantitative measurements of analytes in human body fluids. This aligns with the definition of an IVD.
- Calibration: The calibrators are described as being "for in vitro use in the calibration" of the system for measuring vitamin B12 in human samples. Calibration is a crucial part of ensuring the accuracy of an IVD test.
- Predicate Device: The mention of a "predicate device" which is a "Radioassay" further supports that this is a diagnostic test performed in vitro.
The information provided strongly indicates that this device is designed and intended for in vitro diagnostic use.

Device Description
The VITROS Immunodiagnostic System uses luminescence as the signal in the quantitative and semi-quantitative determination of selected analytes in human body fluids, commonly serum, plasma and urine. Coated microwells are used as the solid phase separation system.
The system is comprised of three main elements:
-
- The VITROS Immunodiagnostic Products range of products, in this case VITROS Immunodiagnostic Products Vitamin B12 Reagent Pack 1/2, VITROS Immunodiagnostic Products Vitamin B12/Folate Reagent Pack 3, VITROS Immunodiagnostic Products Vitamin B12 Calibrators and the VITROS Immunodiagnostic System.
-
- The VITROS Immunodiagnostic System instrumentation, which provides automated use of the immunoassay kits. The VITROS Immunodiagnostic System was cleared for market by a separate 510(k) pre-market notification (K962919).
- Common reagents used by the VITROS System in each assay. The VITROS 3. Immunodiagnostic Products Signal Reagent and VITROS Immunodiagnostic Products Universal Wash Reagent were cleared as part of the VITROS Immunodiagnostic Products Total T3 510(k) pre-market notification (K984310).
The VITROS System and common reagents are dedicated specifically only for use with the VITROS Immunodiagnostic Products range of immunoassay products.

Dear Ms. Zavertnik:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639.
