The Diagnostic Chemicals Limited Magnesium Assay (XB) is for the quantitative determination of magnesium in human serum. Magnesium measurements are used in the diagnosis and treatment of hypomagnesemia (abnormally low levels of magnesium) and hypermagnesemia (abnormally high levels of magnesium). This device is intended for professional use and IN VITRO diagnostic use only.

The Diagnostic Chemicals Limited Magnesium Assay (XB) Standard is used for the callbration of the Diagnostic Chemicals Limited Magnesium Assay (XB) when used for the quantitative determination of magnesium in human serum.

AI/ML Overview

The provided text is a 510(k) premarket notification acceptance letter from the FDA for a Magnesium Assay (XB) device. It confirms the device's substantial equivalence to legally marketed predicate devices. However, this document does not contain the detailed acceptance criteria or the study data that proves the device meets those criteria.

The information requested in your prompt (e.g., acceptance criteria table, sample sizes, ground truth establishment, MRMC studies) is typically found in the technical documentation submitted by the manufacturer as part of the 510(k) application, not in the FDA's acceptance letter itself.

Therefore, I cannot fulfill your request with the provided input. The document mainly states that the device was reviewed and found substantially equivalent, but it doesn't elaborate on how that determination was made in terms of specific performance data and criteria.

Dear Ms. Murray:

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.

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 requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820).
