This document is a 510(k) clearance letter from the FDA for a medical device called "Autostat II Anti-B-2 Glycoprotein I IGA Elisa." It confirms that the device is substantially equivalent to a legally marketed predicate device.

Unfortunately, the provided text does not contain the detailed study information needed to answer your questions regarding acceptance criteria, device performance, sample sizes, ground truth establishment, or clinical study specifics. This document is a regulatory approval letter, not a scientific study report.

Therefore, I cannot provide the requested table and detailed answers based on the given input. The letter only states the device's name, regulation number, regulation name, regulatory class, and product code. It also includes the "Indications for Use" which describes what the device is intended for.

To answer your questions, I would need a different document, such as a summary of safety and effectiveness, a clinical study report, or the 510(k) submission itself, which would detail the performance studies conducted.
