Not Found
The provided text is an FDA 510(k) clearance letter for the KRONUS I123 Acetylcholine Receptor Blocking Antibody Kit (KRONUS Blocking AChRAb RIA Assay Kit). This document focuses on the regulatory approval process and includes the device’s indications for use. It does not contain any information about acceptance criteria, device performance studies, sample sizes, expert qualifications, or ground truth establishment.
Therefore, I cannot provide the requested table and information based directly on the given text.
The information you are requesting, such as acceptance criteria and detailed study results, would typically be found in the manufacturer's 510(k) submission document itself, or potentially in a more comprehensive summary document provided by the FDA, but not in the clearance letter.

Trade/Device Name: KRONUS I123 Acetylcholine Receptor Blocking Antibody Kit Regulation Number: 21 CFR 866.5660 Regulation Name: Multiple autoantibodies immunological test system Regulatory Class: Class II Product Code: NST Dated: May 19, 2008 Received: May 28, 2008
Dear Ms Viele:
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 (OS) 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.

§ 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).
