Intended Use

The Liquichek™ Autoimmune Negative Control is intended for use as an unassayed quality control to monitor indirect immunofluorescent testing for the analytes listed in this package insert.

Device Story

Liquichek™ Autoimmune Negative Control is a liquid, human serum-based quality control material used in clinical laboratories to monitor the performance of indirect immunofluorescent (IFA) assays. It serves as a negative control for detecting antinuclear antibodies (ANA) with various patterns (speckled, centromere, homogenous, mitotic spindle). The device is intended for professional use by laboratory personnel to ensure the accuracy and reliability of autoimmune testing procedures. By providing a stable, known negative sample, it allows clinicians to verify that the IFA test system is functioning correctly, thereby reducing the risk of false-positive results in patient diagnostics.

Clinical Evidence

No clinical data. Stability studies were performed to validate shelf life (2 years at 2-8°C) and open-vial stability (60 days at 2-8°C).

Technological Characteristics

Liquid human serum-based control with added preservatives. Storage at 2°C to 8°C. Designed for use in indirect immunofluorescent (IFA) testing systems.

Indications for Use

Indicated for use as an unassayed quality control material to monitor indirect immunofluorescent testing for antinuclear antibodies (ANA) in human serum samples.

Regulatory Classification

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).

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 (OS) regulation (21 CFR Part 820). 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. {4}------------------------------------------------ Page 2 - If you desire specific information about the application of labeling requirements to your device, or questions on the promotion and advertising of your device, please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 594-3084.
