The summary describes a traditional in vitro diagnostic method (Etest) for determining antimicrobial susceptibility based on a predefined antibiotic gradient and overnight incubation. There is no mention of AI, ML, image processing, or any computational analysis that would suggest the use of these technologies.
No
The device is described as being for "in vitro diagnostic use" and is used to determine the Minimum Inhibitory Concentration (MIC) of antibiotics against bacteria, which is an analytical measurement performed outside the body, not a direct treatment or diagnosis.
Yes
The "Intended Use / Indications for Use" section explicitly states "For in vitro diagnostic use" and describes its function in determining antimicrobial susceptibility and Minimum Inhibitory Concentration (MIC), which are diagnostic activities.
No
The device is described as a "system" comprising a "predefined antibiotic gradient" used on "agar media." This strongly suggests the involvement of physical components (agar plates, antibiotic strips) beyond just software. The description focuses on an in vitro diagnostic method, not a software application processing data.
Yes, this device is an IVD (In Vitro Diagnostic).
The "Intended Use / Indications for Use" section explicitly states: "For in vitro diagnostic use". This is the primary indicator that the device is intended for use outside of a living organism to diagnose or detect a condition.
Furthermore, the description of its function – determining antimicrobial susceptibility and Minimum Inhibitory Concentration (MIC) of bacteria – aligns perfectly with the definition of an in vitro diagnostic device, which is used to examine specimens from the human body to provide information for diagnosis, treatment, or prevention of disease.
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 Enterococcus 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 ug/ml of individual antibiotics against bacteria as tested on agar media by overnight incubation.
This application is for MIC determination of Benzylpenicillin in the range of 0.016 - 256 ug/ml or 0.002 - 32 ug/ml with streptococci other than S. pneumoniae.
Previously cleared applications include non-fastidious Gram positive aerobic bacteria, S. pneumoniae and anaerobic 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).

The seal features a stylized caduceus, a symbol often associated with medicine and healthcare, composed of three intertwined lines forming a shape resembling a bird in flight. The text "DEPARTMENT OF HEALTH & HUMAN SERVICES - USA" is arranged in a circular pattern around the caduceus, indicating the department's name and national affiliation. The seal is presented in black and white, emphasizing its official and formal nature.

Re: K980335 Trade Name: Etest® Benzylpenicillin Regulatory Class: II Product Code: JWY Dated: May 6, 1998 Received: May 8, 1998
Dear Ms. Bolmström:
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 (OS) 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. 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 at (301) 443-6597 or at its internet address "http://www.fda.gov/cdrh/dsmamain.html"
