Intended Use

HardyDisk™ Antimicrobial Sensitivity Disks are used for semi-quantitative in vitro susceptibility testing by the agar diffusion test procedure (Kirby-Bauer) of rapidly growing and certain fastidious bacterial pathogens. Standardized methods for agar diffusion testing have been described for Enterobacteriaceae, Staphylococcus spp., Pseudomonas spp., Acinetobacter spp., Listeria monocytogenes, Enterococcus spp., other streptococci and, by modified procedures, Haemophilus influenzae, Neisseria gonorrhoeae and Streptococcus pneumoniae. HardyDisk™ Cefaclor is indicated for in vitro activity against the Enterobacteriacieae, methicillin sensitive Staphylococcus spp., non-beta lactamase producing Haemophilus spp. and Moraxella catarrhalis.

Device Story

HardyDisk™ Cefaclor 30mcg is an antimicrobial susceptibility test disk used in clinical microbiology laboratories. It utilizes the Kirby-Bauer agar diffusion method to determine bacterial sensitivity to the antibiotic Cefaclor. The disk is placed on agar plates inoculated with patient bacterial isolates; the antibiotic diffuses into the medium, creating a zone of inhibition proportional to the organism's susceptibility. Laboratory technicians measure these zones to categorize bacteria as susceptible, intermediate, or resistant. This information assists clinicians in selecting appropriate antibiotic therapy for patients with bacterial infections. The device provides a standardized, semi-quantitative assessment of antimicrobial activity.

Clinical Evidence

No clinical data. Performance is established through standardized in vitro agar diffusion testing (Kirby-Bauer method) comparing zone of inhibition results to established interpretive criteria for specific bacterial pathogens.

Technological Characteristics

Antimicrobial sensitivity disk containing 30mcg of Cefaclor. Operates via passive diffusion in agar medium. Standardized for Kirby-Bauer disk diffusion susceptibility testing. Non-automated, manual laboratory diagnostic component.

Indications for Use

Indicated for in vitro susceptibility testing of rapidly growing and fastidious bacterial pathogens, including Enterobacteriaceae, methicillin-sensitive Staphylococcus spp., non-beta lactamase producing Haemophilus spp., and Moraxella catarrhalis.

Regulatory Classification

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.

Dear Ms. Traylor:

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.

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