No
The provided text describes a standard in vitro diagnostic assay for Vitamin B12 and does not mention any AI or ML components in its intended use, device description, or performance studies.

No.
The device is an in vitro diagnostic assay used for measuring Vitamin B12 levels to aid in diagnosis, not for treating a condition.

Yes
The text states, "Measurements of vitamin B12 may be used in the diagnosis of B12 deficiency. For in vitro diagnostic use only." This explicitly indicates its use for diagnosis.

No

The device is an in vitro diagnostic assay, which involves chemical reagents and laboratory equipment, not solely software.

Yes, this device is an IVD (In Vitro Diagnostic).

The "Intended Use / Indications for Use" section explicitly states:

  • "The Diazyme Vitamin B12 Assay is for the quantitative determination of Vitamin B12 levels in human serum."
  • "For in vitro diagnostic use only."
  • "The Diazyme Vitamin B12 Calibrator Set is intended for use in the Diazyme Vitamin B12 Assay. For in vitro diagnostic use only."
  • "The Diazyme Vitamin B12 Control Set is intended for use as quality controls for the Diazyme Vitamin B12 Assay. For in vitro diagnostic use only."

These statements clearly indicate that the device is intended to be used outside of the body (in vitro) to diagnose a condition (B12 deficiency) by analyzing a human sample (serum). This aligns directly with the definition of an In Vitro Diagnostic device.

Dear Dr. 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.
