No
The description details a standard immunoenzymometric assay and does not mention any AI or ML components. The "Mentions AI, DNN, or ML" field is also "Not Found".
No
The device is described as an "IN VITRO DIAGNOSTIC USE ONLY" product for measuring Carcinoembryonic Antigen (CEA) and aids in the management of cancer patients by observing changing concentrations, but it does not directly treat or prevent a disease.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "designed for IN VITRO DIAGNOSTIC USE ONLY" and aids "in the management of cancer patients".
No
The device description clearly indicates it is an in vitro diagnostic assay performed within a physical "AIA-PACK" using magnetic beads, antibodies, and a fluorogenic substrate. This involves physical components and chemical reactions, not just software.
Yes, this device is an IVD (In Vitro Diagnostic).
The "Intended Use / Indications for Use" section explicitly states: "ST AIA-PACK CEA is designed for IN VITRO DIAGNOSTIC USE ONLY for the quantitative measurement of Carcinoembryonic Antigen (CEA) in human serum..."
This statement clearly indicates that the device is intended for diagnostic purposes performed outside of the body (in vitro) using human samples.

Intended Use / Indications for Use
ST AIA-PACK CEA is designed for IN VITRO DIAGNOSTIC USE ONLY for the quantitative measurement of Carcinoembryonic Antigen (CEA) in human serum to aid in the management of cancer patients in whom changing concentrations of CEA are observed on specific TOSOH AIA System analyzers.

Device Description
The ST AIA-PACK CEA is a two-site immunoenzymometric assay which is performed entirely in the AIA-PACK. CEA present in the test sample is bound with monoclonal antibody immobilized on a magnetic solid phase and enzyme-labeled monoclonal antibody in the AJA-PACK. The magnetic beads are washed to remove unbound enzyme-labeled monoclonal antibody and are then incubated with a fluorogenic substrate, 4-methylumbelliferyl phosphate (4MUP). The amount of enzyme-labeled monoclonal antibody that binds to the beads is directly proportional to the CEA concentration in the test sample. A standard curve is constructed, and unknown sample concentrations are calculated using this curve.

§ 866.6010 Tumor-associated antigen immunological test system.
(a)
Identification. A tumor-associated antigen immunological test system is a device that consists of reagents used to qualitatively or quantitatively measure, by immunochemical techniques, tumor-associated antigens in serum, plasma, urine, or other body fluids. This device is intended as an aid in monitoring patients for disease progress or response to therapy or for the detection of recurrent or residual disease.(b)
Classification. Class II (special controls). Tumor markers must comply with the following special controls: (1) A guidance document entitled “Guidance Document for the Submission of Tumor Associated Antigen Premarket Notifications (510(k)s) to FDA,” and (2) voluntary assay performance standards issued by the National Committee on Clinical Laboratory Standards.

Statement of Intended Use:
ST AIA-PACK CEA is designed for IN VITRO DIAGNOSTIC USE ONLY for the quantitative measurement of Carcinoembryonic Antigen (CEA) in human serum to aid in the management of cancer patients in whom changing concentrations of CEA are observed on specific TOSOH AIA System analyzers.
Substantial Equivalence:
This Special 510(k) is for a modification in the packaging, incubation period, conjugate concentration and certain components of the conjugate diluent of the AIA-PACK CEA, which was previously cleared as P910006 on February 19, 1993. The intended use, assay principles, antibody type, analyte detected, and performance characteristics of both assays are equivalent.
Conclusion:
The modified ST AIA-PACK CEA, as described in this Special 510(k) is substantially equivalent to the predicate device. The proposed modifications in packaging, incubation period, conjugate and conjugate diluent are not substantial changes and do not affect the safety and effectiveness of the device.

Dear Ms. Nakayama:
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 lisuing (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).
