Intended Use

An enzyme-linked immunosorbant assay (ELISA) for the semiquantitative detection of chromatin reactive antibodies in human serum. The presence of anti-chromatin antibodies can be used in conjunction with clinical findings and other laboratory tests to aid in the diagnosis of drug-induced lupus (DIL) and systemic lupus erythematosus (SLE).

Device Story

QUANTA Lite™ Chromatin ELISA is an in vitro diagnostic test used in clinical laboratories. It detects chromatin reactive antibodies in human serum samples using enzyme-linked immunosorbent assay (ELISA) technology. The device provides semiquantitative results that clinicians use alongside patient clinical history and other diagnostic tests to support the diagnosis of systemic lupus erythematosus (SLE) and drug-induced lupus (DIL).

Clinical Evidence

No clinical data provided in the document; bench testing only.

Technological Characteristics

ELISA-based immunoassay for detection of chromatin reactive antibodies in human serum. Standard laboratory equipment required for plate processing and optical density measurement.

Indications for Use

Indicated for the semiquantitative detection of chromatin reactive antibodies in human serum to aid in the diagnosis of drug-induced lupus (DIL) and systemic lupus erythematosus (SLE) in conjunction with clinical findings and other laboratory tests.

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).

Dear Mr. Myers:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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 reqistration, 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 (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Requlation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
