No
The description focuses on a qualitative technique using an antibiotic gradient and overnight incubation, with no mention of AI, ML, image processing, or data-driven analysis.
No
The device is described as an in vitro diagnostic (IVD) system used for antimicrobial susceptibility testing, which provides information about microorganisms' susceptibility to antibiotics, rather than directly treating a condition.
Yes
The document explicitly states "For in vitro diagnostic use" and describes the system's purpose as "antimicrobial susceptibility testing," which is a diagnostic procedure to determine the susceptibility categories of microorganisms.
No
The device description explicitly states that the system "comprises an antibiotic gradient with MIC break-point concentrations" and is "tested on agar media using overnight incubation." This indicates the device includes physical components (antibiotic gradient, agar media) and a process involving incubation, which are not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
The "Intended Use / Indications for Use" section explicitly states: "For in vitro diagnostic use".
The "Device Description" also describes a system used for "antimicrobial susceptibility testing", which is a type of in vitro diagnostic test.
N/A
Intended Use / Indications for Use
For in vitro diagnostic use: System U3™ is a qualitative technique for antimicrobial susceptibility testing of nonfastidious Gram negative and Gram positive aerobic bacteria, such as Enterobacteriaceae, Pseudomonas, Staphylococcus and Enterococcus species. The system comprises an antibiotic gradient with MIC break-point concentrations and is used to determine the susceptibility categories of microorganisms to different antimicrobial agents, as tested on agar media using overnight incubation. This 510(k) application is for System U3/Norfloxacin susceptibility testing based on the MIC breakpoints of Susceptible ≤ 4 µg/ml, Intermediate 8 µg/ml and Resistant ≥ 16 µg/ml for use with non-fastidious Gram negative and Gram positive aerobic bacteria.

§ 866.1640 Antimicrobial susceptibility test powder.
(a)
Identification. An antimicrobial susceptibility test powder is a device that consists of an antimicrobial drug powder packaged in vials in specified amounts and intended for use in clinical laboratories for determining in vitro susceptibility of bacterial pathogens to these therapeutic agents. Test results are used to determine the antimicrobial agent of choice in the treatment of bacterial diseases.(b)
Classification. Class II (performance standards).

Re: K983486 Trade Name: System U3 for Norfloxacin Requlatory Class: II Product Code: JWY October 2, 1998 Dated: Received: October 5, 1998
Dear Ms. Bolmstrom:
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 aqainst 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 Requlations, 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 Reqister. 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 requlations.

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. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification"(21 CFR 807.97).
