Intended Use

The Liquichek™ ANA Control, Speckled Pattern, Positive, is intended for use as an unassayed quality control to monitor indirect immunofluorescent testirng of antinuclear antibodies (ANA).

Device Story

Liquichek™ ANA Control, Speckled Pattern, Positive is a liquid, human serum-based quality control material. It is used by laboratory personnel to monitor the performance of indirect immunofluorescent (IIF) assays for antinuclear antibodies. The control provides a standardized speckled pattern to verify assay accuracy and precision. It is stored at 2-8°C and remains stable for 60 days once opened. By providing a consistent positive control, it assists clinicians in ensuring the reliability of patient test results, thereby supporting accurate diagnosis of autoimmune conditions.

Clinical Evidence

Bench testing only. Stability studies confirmed 60-day open-vial stability and 2-year shelf life when stored at 2-8°C.

Technological Characteristics

Liquid human serum-based control with added preservatives. Designed for indirect immunofluorescent testing. Storage at 2-8°C. No electronic or software components.

Indications for Use

Indicated for use as an unassayed quality control material to monitor the performance of indirect immunofluorescent testing for antinuclear antibodies (ANA) in clinical laboratory settings.

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).
