Used in clinical laboratories to monitor the performance of indirect immunofluorescent (IIF) assays for ANA detection. Controls are provided as unassayed materials; laboratory personnel use them to verify the accuracy and precision of the testing process. By comparing observed results against expected patterns, clinicians ensure the reliability of patient autoantibody testing, aiding in the diagnosis of autoimmune conditions. ## Clinical Evidence No clinical data. Performance is supported by bench testing, specifically stability studies confirming 60-day open-vial stability and 2-year shelf life when stored at 2-8°C. ## Technological Characteristics Liquid human serum-based control set. Contains preservatives. Four distinct ANA patterns: homogeneous, speckled, centromere, and nucleolar. Storage: 2°C to 8°C. Unassayed quality control material. ## Regulatory 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). ## Predicate Devices - Kallestad™ ANA Positive Control Homogeneous Pattern ([K792610](/device/K792610.md)) - Liquichek™ ANA Control, Centromere Pattern ([K984397](/device/K984397.md)) - Kallestad™ Autoantibody Positive Control ([K792610](/device/K792610.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

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 Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. 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 Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). {7}------------------------------------------------ ### Page 2 - 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.
