The KRONUS Acetylcholine Receptor Antibody (AChRAb) Assay Kit is for the quantitative or qualitative determination of acetylcholine receptor antibody in human serum. The KRONUS Acetylcholine Receptor Antibody(AChRAb) kit is useful as an aid in the differential diagnosis of Myasthenia Gravis.
Not Found
The provided K042248 document is a 510(k) clearance letter from the FDA for the Kronus I125 Acetylcholine Receptor Antibody Kit. This document does not contain the detailed study information, acceptance criteria, or performance data that would be used to prove the device meets acceptance criteria.
FDA 510(k) clearance letters primarily state that the device is substantially equivalent to a legally marketed predicate device and outline the regulatory classification and general controls. They typically do not include the raw data, study design, or performance metrics from the studies submitted in the 510(k) application itself.
Therefore, based solely on the provided text, I cannot extract the information required to populate the requested table and answer the study-related questions.
To answer your request, I would need access to the full 510(k) submission document or a summary of the performance data that was provided to the FDA by Kronus Market Development Associates.

Trade/Device Name: Kronus I125 Acetylcholine Receptor antibody Kit Regulation Number: 21 CFR 866.5660 Regulation Name: Multiple Autoantibodies Immunological Test System Regulatory Class: Class II Product Code: NST Dated: August 16, 2004 Received: August 19, 2004
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 (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

§ 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).
