The summary describes a quality control material for laboratory testing, not a device that processes data or images using AI/ML.
No
The device is described as an "unassayed quality control" to monitor testing for autoantibodies, not to treat any condition.
No
The device is described as an "unassayed quality control" for indirect immunofluorescent testing, indicating its use in monitoring the performance of a diagnostic test, rather than being a diagnostic device itself.
No
The device description clearly states the product is prepared from human serum and provided in liquid form, indicating it is a physical reagent, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for "monitoring indirect immunofluorescent testing for the detection of Scl-70 autoantibodies." This testing is performed in vitro (outside the body) on patient samples (implied by the need to monitor testing for autoantibodies).
- Device Description: The product is prepared from "human serum," which is a biological sample typically used in in vitro diagnostic tests.
- Quality Control: The product is described as an "unassayed quality control." Quality controls are essential components of in vitro diagnostic testing to ensure the accuracy and reliability of the results.
- Predicate Device: The predicate device listed (K984475; Liquichek™ Anti-Scl-70 Control, EIA) is also a quality control for an in vitro diagnostic test (EIA for Scl-70).
All these points strongly indicate that this device is intended to be used in the context of in vitro diagnostic procedures.

§ 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).

Dear Ms. Lloyd
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 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).
