Device Description

Not Found

AI/ML Overview

The provided document is a 510(k) clearance letter from the FDA for a diagnostic device named Autostat™ II Anti-CARDIOLIPIN IgG ELISA. It confirms that the device is substantially equivalent to a legally marketed predicate device. However, this document does not contain the detailed information needed to answer the specific questions about acceptance criteria, study design, expert qualifications, or ground truth establishment.

A 510(k) clearance letter primarily focuses on regulatory aspects and substantial equivalence, not the detailed performance study data. To answer your questions, one would typically need access to the full 510(k) submission, which includes the summary of safety and effectiveness, or a separate publication of the performance study.

Therefore, I cannot provide a table of acceptance criteria and reported device performance or details about the study that proves the device meets those criteria from the information given. The document does not contain:

1. A table of acceptance criteria and reported device performance.
2. Sample sizes for test or training sets, nor data provenance.
3. Information on the number or qualifications of experts used for ground truth.
4. Adjudication methods.
5. Information about MRMC comparative effectiveness studies.
6. Details about standalone algorithm performance.
7. The type of ground truth used.
8. Sample size for the training set.
9. How ground truth for the training set was established.

The document does mention:

• Device Trade Name: Autostat™ II Anti-CARDIOLIPIN IgG ELISA
• Intended Use/Indications For Use: Enzyme linked immunosorbent assay method for the semi-quantitative determination of specific IgG autoantibodies to cardiolipin in human serum. Used as an aid in the diagnosis of diseases associated with elevated levels of anti-cardiolipin antibodies including antiphospholipid syndrome.
• Regulatory Class: II
• Product Code: MID
• Applicant: Cogent Diagnostics Limited
• Device Type: In vitro diagnostic use only.

To get the information you are requesting, you would need to consult the original 510(k) submission documentation (specifically the "Summary of Safety and Effectiveness") which may be available through the FDA's databases, or any peer-reviewed publications that Cogent Diagnostics Limited might have produced regarding the validation of this specific assay.

Dear Ms. Knight:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization. To determine if it does, you should contact the Centers for Disease Control and Prevention (CDC) at [phone].

This letter will allow you to begin marketing your device as described in your 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 advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at [phone]. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification"(21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number [phone] or [phone], or at its internet address "http://www.fda.gov/cdrh/dsma/dsmamain.html".

Sincerely yours.

Regulation Number and Section

§ 866.5660 Multiple autoantibodies immunological test system.

(a)
Identification. A multiple autoantibodies immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the autoantibodies (antibodies produced against the body's own tissues) in serum and other body fluids. Measurement of multiple autoantibodies aids in the diagnosis of autoimmune disorders (disease produced when the body's own tissues are injured by autoantibodies).(b)
Classification. Class II (performance standards).
