Intended Use

The Zeus Scientific, Inc., B. burgdorferi Western Blot Test System is designed for the qualitative detection of IgM class antibodies to specific proteins associated with B. burgdorferi, the causative agent of Lyme Disease. This test system is intended to be used for testing human serum samples which have been found to be positive or equivocal by an EIA or IFA screening procedure. The test is therefore intended to provide supportive evidence of infection with Borrelia burgdorferi.

Device Story

The Borrelia burgdorferi IgM Western Blot Test System is an in vitro diagnostic assay used in clinical laboratories. It processes human serum samples that have already screened positive or equivocal via EIA or IFA. The test detects IgM class antibodies specific to B. burgdorferi proteins. The procedure involves Western Blotting, where proteins are separated and probed for antibody binding. Results provide supportive evidence of Lyme disease infection to assist clinicians in diagnosis. The device is intended for prescription use only.

Clinical Evidence

No clinical data provided in the document; the document is a 510(k) clearance letter.

Technological Characteristics

In vitro diagnostic Western Blot test system for qualitative antibody detection. Utilizes standard laboratory immunoassay techniques for protein separation and detection of IgM class antibodies to B. burgdorferi.

Indications for Use

Indicated for qualitative detection of IgM class antibodies to B. burgdorferi in human serum samples previously testing positive or equivocal by EIA or IFA screening. Used as supportive evidence of Lyme disease infection.

Regulatory Classification

Identification

Treponema pallidum treponemal test reagents are devices that consist of the antigens, antisera and all control reagents (standardized reagents with which test results are compared) which are derived from treponemal sources and that are used in the fluorescent treponemal antibody absorption test (FTA-ABS), the Treponema pallidum immobilization test (T.P.I.), and other treponemal tests used to identify antibodies to Treponema pallidum directly from infecting treponemal organisms in serum. The identification aids in the diagnosis of syphilis caused by bacteria belonging to the genus Treponema and provides epidemiological information on syphilis.

Dear Mr. Kopnitsky:

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.

Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization. To determine if it does, you should contact the Centers for Disease Control and Prevention (CDC) at [phone].

This letter will allow you to begin marketing your device as described in your 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.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at [phone]. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
