The Immuno Concepts IgG Anti-nDNA Fluorescent Test System is for in vitro diagnostic use for the qualitative detection and semi-quantitation of anti-nDNA antibodies of the IgG class in human serum by manual fluorescent microscopy or with the Image Navigator® Fluorescence Semiautomated Microscope. The Immuno Concepts IgG Anti-IDNA Fluorescent Test System is to be used as an aid in the diagnosis of Systemic Lupus Erythematosus (SLE) in conjunction with other clinical and laboratory findings. A trained operator must confirm results generated with the Image Navigator® semi-automated device and software.

The provided text is a 510(k) premarket notification clearance letter from the FDA for the "Immuno Concepts IgG Anti-nDNA Fluorescent Test System" and the "Image Navigator® Fluorescence Semiautomated Microscope." It details the device's indications for use and general regulatory information but does not contain the specific acceptance criteria, study details, or performance data that would allow for a complete answer to your request.

Therefore, I cannot extract the following information from the provided text:

• A table of acceptance criteria and the reported device performance
• Sample size used for the test set and the data provenance
• Number of experts used to establish the ground truth for the test set and the qualifications of those experts
• Adjudication method for the test set
• Whether a multi-reader multi-case (MRMC) comparative effectiveness study was done, or the effect size
• Whether a standalone (algorithm only) performance study was done
• The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
• The sample size for the training set
• How the ground truth for the training set was established

The document primarily states that the FDA has determined the device is substantially equivalent to legally marketed predicate devices. To find the detailed study information, one would typically need to review the full 510(k) summary or the pivotal study report submitted by the manufacturer to the FDA, which is not included in this clearance letter.

Instrument: The Immuno Concepts Image Navigator is an automated system consisting of a fluorescent microscope and software that acquires, interprets, stores, and displays digital indirect immunofluorescent slides. The Image Navigator can only be used with cleared or approved Immuno Concepts in vitro diagnostic assays that are indicated for use on the microscope. All suggested results generated by the Image Navigator software must be confirmed by trained laboratory personnel.

Assay: This is an indirect fluorescent antibody test for the semi-quantitative detection of IgG antinuclear antibody (ANA) in human serum by manual fluorescent microscopy or with the Image Navigator Fluorescence Semi-Automated Microscope. This test system uses transfected HEp-2000® cells, which allow specific identification of autoantibodies to the SSA/Ro antigen. Autoantibodies to SSA/Ro may show a distinctive staining pattern on the transfected cells. When this pattern is present, it is considered to be confirmatory evidence that anti-SSA/Ro antibodies are present. Absence of this distinctive pattern does not rule out the possible presence of anti-SSA/Ro antibodies. This test system is to be used as an aid in the detection of antibodies associated with systemic rheumatic disease in conjunction with other laboratory and clinical findings. A trained operator must confirm results generated with the Image Navigator semi-automated device and software.

The provided document serves as an FDA 510(k) clearance letter for the HEp-2000® Fluorescent ANA/Ro Test System; Image Navigator by Immuno Concepts. While it outlines the device's indications for use and classification, it does not include detailed information regarding acceptance criteria, study design, specific performance metrics, or ground truth establishment.

Therefore, I cannot fulfill the request to describe the acceptance criteria and the study that proves the device meets them based solely on the provided text. The document is an administrative clearance, not a scientific study report.

To answer your request, a different type of document, such as a summary of safety and effectiveness (SSED) from the FDA or the original submission's performance data, would be needed.
