No
The summary describes a quantitative in vitro diagnostic assay kit for Lithium in human serum, which is a standard laboratory test and does not mention any AI/ML components or capabilities.

No
This device is an in vitro diagnostic (IVD) assay kit used to measure Lithium levels in human serum, which aids in monitoring drug dosage and preventing toxicity. It does not directly treat a disease or condition, but rather provides information for patient management.

Yes
Explanation: The device is described as an "in vitro determination of Lithium in human serum" to monitor drug dosage and avoid toxicity in patients with bipolar disorder, which indicates its use in diagnosing or monitoring patient health.

No

The device is described as a "Liquid Enzymatic Assay Kit" for the quantitative determination of Lithium in human serum. This description strongly suggests a chemical or biological assay kit, which is a physical product containing reagents and potentially other hardware components, not a software-only device.

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

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

"Diazyme Liquid Enzymatic Assay Kit is for quantitative in vitro determination of Lithium in human serum."

The term "in vitro" is the key indicator that this device is intended for use outside of the living body, which is the definition of an IVD. The purpose of the test (measuring Lithium in human serum) further confirms its role in diagnosing or monitoring a medical condition (bipolar disorder treatment and toxicity avoidance).

Trade/Device Name: Diazyme Liquid Stable Enzymatic Lithium Regulation Number: 21 CFR 862.3560 Regulation Name: Lithium Test System Regulatory Class: II Product Code: JII Dated: July 11, 2008 Received: August 18, 2008

Dear Dr. 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.

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).

This letter will allow you to begin marketing your device as described in your Section 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 information about the application of labeling requirements to your device, or questions on the promotion and advertising of your device, please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (240) 276-0490. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150 or at its Internet address at http://www.fda.gov/cdrh/industry/support/index.html.

Sincerely yours.
