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.
§ 866.5100 Antinuclear antibody immunological test system.
(a)
Identification. An antinuclear antibody immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the autoimmune antibodies in serum, other body fluids, and tissues that react with cellular nuclear constituents (molecules present in the nucleus of a cell, such as ribonucleic acid, deoxyribonucleic acid, or nuclear proteins). The measurements aid in the diagnosis of systemic lupus erythematosus (a multisystem autoimmune disease in which antibodies attack the victim's own tissues), hepatitis (a liver disease), rheumatoid arthritis, Sjögren's syndrome (arthritis with inflammation of the eye, eyelid, and salivary glands), and systemic sclerosis (chronic hardening and shrinking of many body tissues).(b)
Classification. Class II (performance standards).
