Intended Use

The Cheshire Diagnostics Limited QAß2A IgG Elisa Kit HRP is an Enzyme Linked Immunoassay for the in vitro semiquantitative detection of IgG antibodies to ß2-Glycoprotein-I in human serum. The presence of ß2-GPI antibodies can be used in conjunction with other serological tests and clinical findings to aid in the assessment of the risk from thrombosis in patients with Systemic Lupus Erythematosus or other lupus like disorders.

Device Story

Device is an Enzyme Linked Immunoassay (ELISA) kit for in vitro diagnostic use. Input: human serum samples. Principle: detects IgG antibodies to ß2-Glycoprotein-I (ß2-GPI). Output: semiquantitative measurement of antibody levels. Used in clinical laboratory settings by trained laboratory personnel. Results are interpreted by clinicians alongside other serological tests and clinical findings to assess thrombosis risk in patients with Systemic Lupus Erythematosus or lupus-like disorders.

Clinical Evidence

No clinical data provided in the document; substantial equivalence is based on analytical performance characteristics typical of ELISA-based immunological test systems.

Technological Characteristics

Enzyme Linked Immunoassay (ELISA) kit; utilizes HRP (Horseradish Peroxidase) conjugate for detection; in vitro diagnostic test system; class II device (21 CFR 866.5660).

Indications for Use

Indicated for in vitro semiquantitative detection of IgG antibodies to ß2-Glycoprotein-I in human serum to aid in assessing thrombosis risk in patients with Systemic Lupus Erythematosus or lupus-like disorders.

Regulatory Classification

Identification

A multiple autoantibodies immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the autoantibodies (antibodies produced against the body's own tissues) in serum and other body fluids. Measurement of multiple autoantibodies aids in the diagnosis of autoimmune disorders (disease produced when the body's own tissues are injured by autoantibodies).

Dear Mr. Stringer:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced aboye 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 the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
