No
The device description and intended use clearly describe a traditional Western blot assay kit, which relies on biochemical reactions and visual interpretation, not AI/ML algorithms. The "Mentions AI, DNN, or ML" section is explicitly marked as "Not Found".
No
The device is an in vitro diagnostic test for detecting B. burgdorferi infection, not for treating a disease.
Yes
The "Intended Use / Indications for Use" section states that the kit is "intended to provide supportive evidence of infection with B. burgdorferi," which directly indicates its use in diagnosing a medical condition.
No
The device description clearly lists physical components like nitrocellulose strips, controls, buffers, and substrates, indicating it is a hardware-based diagnostic kit, not software only.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the kit is "intended to provide supportive evidence of infection with B. burgdorferi by determining the specific protein reactivities of human serum specimens". This involves testing human samples in vitro (outside the body) to diagnose or provide information about a disease state.
- Device Description: The device is a "collection of cGMP manufactured critical components needed to perform a Western blot test that will detect B. burgdorferi IgM antibody in naturally infected humans." This describes a test kit designed for laboratory use on biological samples.
- Intended User / Care Setting: The intended users are "clinical laboratory professionals in public health laboratories and clinical laboratories," which are typical settings for performing in vitro diagnostic tests.
The definition of an IVD is a medical device that is used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening. This device clearly fits that description.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The two devices were substantially equivalent when tested with first physician visit, verified infected patient samples and with randomly selected enzyme immunoassay positive patient samples. The Applicant Device claims higher specificity than the Predicate Device with blood samples from random blood donors and from patients with syphilis antibody, rheumatoid arthritis, and systemic lupus erythematosus.

§ 866.3830
Treponema pallidum treponemal test reagents.(a)
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), theTreponema pallidum immobilization test (T.P.I.), and other treponemal tests used to identify antibodies toTreponema pallidum directly from infecting treponemal organisms in serum. The identification aids in the diagnosis of syphilis caused by bacteria belonging to the genusTreponema and provides epidemiological information on syphilis.(b)
Classification. Class II (performance standards).

Device Description
The device is a collection of cGMP manufactured critical components needed to perform a Western blot test that will detect B. burgdorferi IgM antibody in naturally infected humans. It includes nitrocellulose strips upon which sodium dodecyl sulfate solubilized and polyacrylamide separated B. burgdorferi proteins have been transferred, an IgM Positive Control, a Negative Control, an anti-IgM alkaline phosphatase concentrate, a buffer concentrate, diluent powder, an NBT/BCIP substrate, Blot Reading Guide, Package Insert, and Results Record Forms.
Intended Use
The BBI-Biotech B. burgdorferi IgM Western blot kit is intended to provide supportive evidence of infection with B. burgdorferi by determining the specific protein reactivities of human serum specimens previously found to be reactive on enzyme immunoassay or indirect immunofluorescence screening assays. The kits will be made available to clinical laboratory professionals in public health laboratories and clinical laboratories.
Technological Comparison with the Predicate Device
Both devices use the same type of technology. They differ primarily in the strains of B. burgdorferi used, the type of initial antigen preparation, the requirement for a pre-wetting step, the length of incubation times, the standardization of substrate incubation, the method used to identify bands of interest, and the positive interpretation criterion.

Dear Ms. Petit:
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 (770)488-7655.
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 (301) 594-4588.
