The document describes a laboratory assay for measuring vitamin B12 levels and does not mention any AI or ML components.
No
This device is for the quantitative determination of vitamin B12, which is used in diagnosis, not direct treatment.
Yes
The "Intended Use / Indications for Use" section states: "Measurements obtained by this device are used in the diagnosis and treatment of anemias of gastrointestinal malabsorption." This explicitly indicates the device's role in diagnosis.
No
The device description clearly indicates it is a reagent and diluent used with the AxSYM System, which is a hardware analyzer. It is not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states the device is for the "quantitative determination of vitamin B12 in human serum or plasma." This is a test performed on biological samples in vitro (outside the body).
- Purpose: The measurements obtained are "used in the diagnosis and treatment of anemias of gastrointestinal malabsorption." This indicates the device is used for medical purposes related to diagnosing a condition.
- Device Description: The description details a "Microparticle Enzyme Intrinsic Factor assay," which is a laboratory test method.
- Specimen Type: The assay is performed on "human serum or plasma," which are biological specimens.
All of these points align with the definition of an In Vitro Diagnostic device.

510(k) Summary Abbott AxSYM® B12
Summary of Safety and Effectiveness Information Supporting a Substantially Equivalent Determination
The following information as presented in the Premarket Notification [510(k)] for Abbott AxSYM B12 constitutes data supporting a substantially equivalent determination. Substantial equivalence has been demonstrated between the Abbott AxSYM B12 assay and the Abbott ARCHITECT® B12 assay. The intended use for both assays is for the quantitative determination of vitamin B12 in human serum or plasma.
The AxSYM B12 assay is a Microparticle Enzyme Intrinsic Factor assay for the quantitative determination of vitamin B12 in human serum or plasma. The AxSYM B12 assay is calibrated with Abbott B12 Calibrators. Abbott B12 Controls are assayed for the verification of the accuracy and precision of the Abbott AxSYM System.
A correlation analysis between the AxSYM B12 and the ARCHITECT B12 assay yielded the following results.
| Regression Method | n | r | Slope | Intercept |
|---|---|---|---|---|
| Least Squares | 441 | 0.98 | 1.09 | 3.7 |
| Passing-Bablok | 1.12 | -13.9 |
n = number of specimens
1 = correlation coefficient

Dear Ms. Prochniak:
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.
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.
