More Information

Not Found

No
The document describes a quantitative turbidimetry assay for measuring complement proteins and does not mention any AI or ML components.

No
The device is described as a reagent and calibrator system used for the quantitative determination of Complement C3 and C4 concentrations in human serum or plasma. This is a diagnostic function, not a therapeutic one.

Yes
The device is intended for the quantitative determination of Complement C3 and C4 concentrations in human serum or plasma, which provides data used in diagnosing and monitoring various medical conditions. The performance studies show comparisons to established chemistry test systems, confirming its role in diagnostic testing.

No

The device description clearly states that the device is a "reagent kit" containing "cartridges" and "bottles," which are physical components, not software. The intended use also describes the use of these reagents in conjunction with a physical system (SYNCHRON LX® Systems).

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

Here's why:

  • Intended Use: The intended use explicitly states the quantitative determination of Complement C3 and C4 concentration in human serum or plasma. This is a diagnostic measurement performed in vitro (outside the body) on biological samples.
  • Device Description: The device consists of reagents and a calibrator used in conjunction with a system (SYNCHRON LX® Systems) to perform these tests. This aligns with the typical components of an IVD system.
  • Performance Studies: The document describes performance studies like method comparison and imprecision, which are standard evaluations for IVD devices to demonstrate their analytical performance.
  • Predicate Devices: The listed predicate devices are also described as reagents and calibrators for similar tests, further indicating that this device falls within the IVD category.

The core function of the device is to analyze biological samples (serum or plasma) to provide diagnostic information (concentration of C3 and C4), which is the definition of an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The data in the Premarket Notification on safety and effectiveness supports a finding of substantial equivalence to chemistry test systems already in commercial distribution.

Equivalence is demonstrated through method comparison, linearity, and imprecision experiments.

Dear Ms. Walker:

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.
