Intended Use

For the in-vitro qualitative screening IgG, M autoantibodies against B2-glycoprotein 1 (B2GP1) present in human serum. This kit may be used in conjunction with anticardiolipin assays and clinical information to aid the diagnosis of thrombosis in at risk patients having, for example, antiphospholipid syndrome (APS) or systemic lupus erythematosus (SLE).

Device Story

Bindazyme® Anti-B2 GP1 Screen EIA Test Kit is an enzyme immunoassay (EIA) for qualitative detection of IgG and IgM autoantibodies against B2-glycoprotein 1 in human serum. Used in clinical laboratory settings by trained personnel. Input: patient serum sample. Process: EIA methodology involving antigen-antibody binding and enzymatic colorimetric detection. Output: qualitative result indicating presence or absence of autoantibodies. Clinical utility: aids diagnosis of thrombosis in patients with conditions like APS or SLE when used alongside anticardiolipin assays and clinical evaluation.

Clinical Evidence

No clinical data provided in the document; the submission relies on the substantial equivalence determination process for an in vitro diagnostic test.

Technological Characteristics

Enzyme immunoassay (EIA) test kit for qualitative detection of autoantibodies. Utilizes standard laboratory equipment for colorimetric analysis. No specific materials, software, or connectivity features described.

Indications for Use

Indicated for in-vitro qualitative screening of IgG and IgM autoantibodies against B2-glycoprotein 1 (B2GP1) in human serum. Used as an aid in diagnosing thrombosis in at-risk patients, such as those with antiphospholipid syndrome (APS) or systemic lupus erythematosus (SLE).

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. Geller:

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 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 (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 Regulation (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.
