The device description details a quantitative immunoassay based on turbidity measurement and a calibration curve. There is no mention of AI or ML in the device description, intended use, or performance studies. The "Mentions AI, DNN, or ML" field is explicitly marked as "Not Found".
No.
This device is an in vitro diagnostic (IVD) assay used for the quantitative determination of C-Reactive Protein, which aids in the evaluation of infection and inflammatory disorders. It does not directly treat or prevent any disease, but rather provides diagnostic information.
Yes
The intended use explicitly states that the device is for "in vitro diagnostic use in the quantitative determination of the concentration of C-Reactive Protein (CRP) in human serum and plasma...Such measurements are used in the evaluation of infection, tissue injury, inflammatory disorders, and associated diseases." This directly indicates its role in diagnosis.
No
The device is an in vitro diagnostic assay that includes reagents and calibrators, which are physical components, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
The document explicitly states in the "Intended Use / Indications for Use" and "Device Description" sections that the ADVIA CHEMISTRY C-Reactive Protein_2 assay and its calibrators are "for in vitro diagnostic use". This is the defining characteristic of an IVD.

Intended Use / Indications for Use
The ADVIA Chemistry C-Reactive Protein_2 assay is for in vitro diagnostic use in the quantitative determination of the concentration of C-Reactive Protein (CRP) in human serum and plasma (lithium heparin) on the ADVIA Chemistry systems. Such measurements are used in the evaluation of infection, tissue injury, inflammatory disorders, and associated diseases. Increases in CRP values are non-specific for many disease processes and should not be interpreted without a complete clinical evaluation.
The ADVIA Chemistry C-Reactive Protein_2 Calibrators are for in vitro diagnostic use in the calibration of ADVIA Chemistry systems for the C-Reactive Protein 2 (CRP 2) method.

Device Description
The ADVIA Chemistry C-Reactive Protein_2 (CRP_2) assay is for in vitro diagnostic use in the quantitative determination of the concentration of C-Reactive Protein in human serum and plasma on the ADVIA® Chemistry systems. The ADVIA Chemistry C-Reactive Protein_2 Calibrators are used to calibrate this method. The proposed labeling indicates the ADVIA Chemistry CRP_2 reagents and Calibrators are for use on the family of ADVIA Chemistry Systems (1200 / 1650 / 1800 / 2400).
The CRP_2 latex reagent is a suspension of uniform polystyrene latex particles coated with rabbit anti-CRP antibody. When serum or plasma containing CRP is mixed with the latex reagent, agglutination takes place resulting in an increase in the turbidity. This turbidity is measured at 571 nm. The CRP concentration in serum or plasma is determined from a calibration curve that is generated with the calibrators.
The ADVIA® Chemistry C-Reactive Protein_2 Calibrators consist of six (6) levels of protein stabilized matrices containing varying concentrations of recombinant human CRP. The Calibrators have targeted expected values (lot specific) of 0, 5, 20, 40, 160, and 320 mg/L.
The calibrators (1 mL/vial) and ready to use. Storage is at 2 - 8℃.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Substantial equivalence was demonstrated by testing several performance characteristics including imprecision, method comparison, interfering substances, serum/plasma equivalency, and analytical range. The following tables summarize the precision (total), interfering substances, analytical range, and method comparison results.
All of the evaluation studies gave acceptable results compared to the predicate devices. These studies support that the ADVIA Chemistry C-Reactive Protein_2 assay is substantially equivalent to the ADVIA Chemistry C-Reactive Protein assay that is currently marketed.

Dear Dr. Liu:
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 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.
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 Part 801); 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

Page 2 -
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) 276-0450.
