Intended Use

Etest® is an agar-based gradient technique for quantitative antifungal susceptibility testing of Candida species. It uses a predefined concentration gradient of the specific antifungal agent to determine the Minimum Inhibitory Concentration (MIC) in ug/mL inhibiting the growth of the test organism under defined conditions. This 510k submission is for an application for in wire diagnostic use of Etest for MIC determination of fluconazole, itraconazole and flucytosine with Candida species.

Device Story

Etest is an agar-based diagnostic tool for determining the Minimum Inhibitory Concentration (MIC) of antifungal agents against Candida species. The device consists of a predefined concentration gradient of an antifungal agent (fluconazole, itraconazole, or flucytosine) on a test strip. In a laboratory setting, the strip is applied to an inoculated agar plate. As the antifungal agent diffuses into the agar, it creates a stable concentration gradient. After incubation, the MIC is determined by observing the point where the zone of inhibition intersects the strip. This quantitative result assists clinicians in selecting appropriate antifungal therapy for patients with Candida infections. The device is intended for professional use in clinical microbiology laboratories.

Clinical Evidence

No clinical data provided. The submission relies on the established performance of the Etest agar-based gradient technique for MIC determination.

Technological Characteristics

Agar-based gradient diffusion technique. Consists of a test strip containing a predefined concentration gradient of antifungal agents (fluconazole, itraconazole, or flucytosine). Quantitative measurement of MIC in µg/mL. In vitro diagnostic device.

Indications for Use

Indicated for quantitative antifungal susceptibility testing (MIC determination) of Candida species using fluconazole, itraconazole, or flucytosine. For in vitro diagnostic use by prescription.

Regulatory Classification

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.

Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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 (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). {1}------------------------------------------------ #### Page 2 This letter will allow you to begin marketing your device as described in your Section 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 information about the application of labeling requirements to your device, or questions on the promotion and advertising of your device, please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 594-3084.
