The document describes a traditional antimicrobial susceptibility testing method (Etest) based on a predefined antibiotic gradient and overnight incubation. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in medical devices.
No
Explanation: The device is for in vitro diagnostic use, specifically for determining antimicrobial susceptibility and Minimum Inhibitory Concentration (MIC) of bacteria. It does not directly treat or alleviate a disease, but rather provides information for diagnosis and treatment decisions.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states "For in vitro diagnostic use." Additionally, the device is described as determining antimicrobial susceptibility and Minimum Inhibitory Concentration (MIC), which are diagnostic activities.
No
The device description is not found, but the intended use describes a system comprising a predefined antibiotic gradient used to determine MIC on agar media by overnight incubation. This strongly suggests a physical component (the antibiotic gradient strip and agar media) is integral to the device's function, making it a combination product or a hardware device with software, not a software-only medical device.
Yes, based on the provided text, this device is an IVD (In Vitro Diagnostic).
The "Intended Use / Indications for Use" section explicitly states:
"For in vitro diagnostic use:"
This statement directly identifies the device as being intended for use in vitro (outside of a living organism) for diagnostic purposes. The subsequent description of determining antimicrobial susceptibility of bacteria further supports this classification, as this is a common type of in vitro diagnostic test.
N/A
Intended Use / Indications for Use
For in vitro diagnostic use:
Etest is a quantitative technique for the determination of antimicrobial susceptibility of both non-fastidious Gram negative and Gram positive aerobic bacteria, such as Enterobacteriaceae, Pseudomonas, Staphylococcus and Enterocccus species and fastidious bacteria, such as anaerobes, Pneumococcus and Haemophilus species. The system comprises a predefined antibiotic gradient which is used to determine the Minimum Inhibitory Concentration (MIC) in µg/ml of individual antibiotics against bacteria as tested on agar media by overnight incubation.
This Etest 510(k) application is for MIC determination of Ceftazidime in the range of 0.016 - 256 µg/ml with Gram negative and Gram positive aerobic bacteria and H. influenzae.

§ 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: K971694 Trade Name: Etest® for Ceftazidime Regulatory Class: II Product Code: JWY Dated: April 29, 1997 Received: May 07, 1997
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 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.

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). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its internet address "http://www.fda.gov/cdrh/dsmamain.html".
Sincerely yours.
