No
The summary describes a standard enzymatic assay for measuring homocysteine levels and contains no mention of AI or ML technologies.

No.
The device is for in vitro diagnostic (IVD) use, intended for quantitative determination of homocysteine in human samples to assist in diagnosis and treatment, rather than directly providing therapy.

Yes
The "Intended Use / Indications for Use" section states that the reagents "can assist in the diagnosis and treatment of patients suspected of having hyperhomocysteinemia and homocystinuria." This indicates its use in identifying or confirming a medical condition, which is the definition of a diagnostic device.

No

The 510(k) summary describes an in vitro diagnostic (IVD) assay, which is a chemical reagent-based test, not a software-only medical device.

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

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

  • "intended for the in vitro quantitative determination of total L-homocysteine in human serum or plasma." The phrase "in vitro" is a key indicator of an IVD, meaning it is used to test samples taken from the body, rather than being used directly on or in the body.
  • "The reagents can assist in the diagnosis and treatment of patients suspected of having hyperhomocysteinemia and homocystinuria." This indicates the device is used for medical purposes related to diagnosis and treatment, which is a core function of IVDs.

§ 862.1377 Urinary homocystine (nonquantitative) test system.

(a)
Identification. A urinary homocystine (nonquantitative) test system is a device intended to identify homocystine (an analogue of the amino acid cystine) in urine. The identification of urinary homocystine is used in the diagnosis and treatment of homocystinuria (homosystine in urine), a heritable metabolic disorder which may cause mental retardation.(b)
Classification. Class II.

Trade/Device Name: Diazyme Homocysteine Enzymatic Assay for Cobas Integra® Regulation Number: 21 CFR8862.1377 Regulation Name: Urinary homocystine (nonquantitative) test system Regulatory Class: Class II Product Code: LPS Dated: May 23, 2006 Received: May 26, 2006

Dear Mr. Strickland:

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).
