The device is a physical disc used in a standardized laboratory procedure for determining bacterial susceptibility to an antibiotic. The interpretation relies on comparing measured zone sizes to established standards, not on AI/ML algorithms.
No
This device is an in vitro diagnostic product used to determine the susceptibility of bacteria to Cefdinir, which aids in selecting appropriate antimicrobial therapy, but it does not directly treat or diagnose a patient.
Yes
This device is used for "in vitro agar diffusion susceptibility testing" to "determine the susceptibility of bacteria to Cefdinir," which is a diagnostic purpose to guide antimicrobial therapy.
No
The device description clearly states it is a physical product: "Antimicrobial Susceptibility Test Discs are used for semi-quantitative in vitro susceptibility testing by standardized agar diffusion test procedures." and "Cefdinir Susceptibility Test Discs are prepared by impregnating high quality paper with accurately determined amounts of Cefdinir". This indicates a hardware component (the discs).
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The document explicitly states the intended use is "for in vitro agar diffusion susceptibility testing." "In vitro" means "in glass" or "in the lab," referring to tests performed outside of a living organism.
- Purpose: The purpose is to "determine the susceptibility of bacteria to Cefdinir." This is a diagnostic test to help guide treatment decisions.
- Device Description: The description details a product used in a laboratory setting (Antimicrobial Susceptibility Test Discs) for a diagnostic procedure (agar diffusion susceptibility testing).
- Regulatory References: The document mentions FDA approval and references standardized procedures from organizations like the FDA, WHO, and NCCLS, which are relevant to IVD regulation and standards.
- Clinical Context: The results of the test (susceptible, intermediate, or resistant) are used to determine the "agent(s) most suitable for use in antimicrobial therapy," directly impacting patient care based on laboratory findings.
All of these points align with the definition and characteristics of an In Vitro Diagnostic device.

Zone sizes used for interpretation of tests, including control organism limits, were determined by the antimicrobic manufacturer, Parke-Davis, a Division of Warner-Lambert Co., and received FDA approval under NDA Nos. 50-739 and 50-749.
Cefdinir Susceptibility Test Discs are prepared by impregnating high quality paper with accurately determined amounts of Cefdinir supplied by the manufacturer. Parke-Davis. Each Cefdinir disc is clearly marked on both sides with the agent and content. Cefdinir discs are furnished in cartridges of 50 discs each. Cefdinir cartridges are packed as either a single cartridge in a single box, or in a package containing ten cartridges.
Agar diffusion methods employing dried filter paper discs impregnated with specific concentrations of antimicrobial agents were developed in the 1940's. In order to eliminate or minimize variability in the testing, Bauer et al developed a standardized procedure in which Mueller Hinton Agar was selected as the test medium.
Various regulatory agencies and standards-writing organizations subsequently published standardized reference procedures based on the Bauer-Kirby method. Among the earliest and most widely accepted of these standardized procedures were those published by the U.S. Food and Drug Administration (FDA) and the World Health Organization (WHO). The procedure was adopted as a consensus standard by the National Committee for Clinical Laboratory Standards (NCCLS) and is periodically updated. The latest NCCLS documents are M2-A6 (1/97) and M100-S8 (1/98).
Discs containing a wide variety of antimicrobial agents are applied to the surface of Mueller Hinton Agar plates [or Haemophilus Test Medium Agar for Haemophilus influenzae or Mueller Hinton Agar with 5% Sheep Blood for Streptococcus pneumoniae] inoculated with pure cultures of clinical isolates. Following incubation, the plates are examined and the zones of inhibition surrounding the discs are measured and compared with established zone size ranges for individual antimicrobial agents in order to determine the agent(s) most suitable for use in antimicrobial therapy. The determination as to whether the organism in question is susceptible (S), intermediate (I), or resistant (R) to an antimicrobial agent is made by comparing zone sizes to those found in the respective organism tables of National Committee for Clinical Laboratory Standards (NCCLS) Document M2-A6 ("Performance Standards for Antimicrobial Disk Susceptibility Tests - Sixth Edition, Approved Standard", 1/97) and of NCCLS Document M100-S8 ("Performance Standards for Antimicrobial Susceptibility Testing", Eighth Informational Supplement, 1/98).

§ 866.1620 Antimicrobial susceptibility test disc.
(a)
Identification. An antimicrobial susceptibility test disc is a device that consists of antimicrobic-impregnated paper discs used to measure by a disc-agar diffusion technique or a disc-broth elution technique the in vitro susceptibility of most clinically important bacterial pathogens to antimicrobial agents. In the disc-agar diffusion technique, bacterial susceptibility is ascertained by directly measuring the magnitude of a zone of bacterial inhibition around the disc on an agar surface. The disc-broth elution technique is associated with an automated rapid susceptibility test system and employs a fluid medium in which susceptibility is ascertained by photometrically measuring changes in bacterial growth resulting when antimicrobial material is eluted from the disc into the fluid medium. Test results are used to determine the antimicrobial agent of choice in the treatment of bacterial diseases.(b)
Classification. Class II (performance standards).

Dear Ms. Weinknecht:
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.
