Laboratory personnel inoculate panels with bacterial isolates; incubate for 16-24 hours. Principle of operation involves observing visible growth or color changes in biochemical substrates. Lowest concentration of antimicrobial agent showing no visible growth is recorded as the Minimum Inhibitory Concentration (MIC). Biochemical substrates identify organisms. Used in clinical microbiology laboratories to guide antibiotic therapy by determining pathogen susceptibility. Results assist clinicians in selecting effective antimicrobial treatments for patients with bacterial infections. ## Clinical Evidence Bench testing and clinical evaluation performed at two sites using 334 gram-negative and gram-positive strains. Essential Agreement (EA) was 99.8-100%; Category Agreement (CA) was 100%. No Major or Very Major errors observed. Reproducibility testing (12 organisms) showed 99.5% agreement within ±1 dilution. QC endpoints were within NCCLS ranges. No clinical data for S. pneumoniae. ## Technological Characteristics Frozen microtiter panels containing twofold dilutions of antimicrobial agents (Minocycline 0.03-32 mcg/ml). Sensing principle: visual observation of bacterial growth or colorimetric change in biochemical substrates. Incubation: 16-24 hours. Manual or automated interpretation of growth endpoints. ## Regulatory 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. ## Predicate Devices - Pasco MIC and MIC/ID panels ([K980955](/device/K980955.md)) - Pasco MIC and MIC/ID panels ([K974362](/device/K974362.md)) - Pasco MIC and MIC/ID panels ([K973317](/device/K973317.md)) - Pasco MIC and MIC/ID panels ([K973695](/device/K973695.md)) - Pasco MIC and MIC/ID panels ([K972567](/device/K972567.md)) - Pasco MIC and MIC/ID panels ([K971951](/device/K971951.md)) - Pasco MIC and MIC/ID panels ([K946126](/device/K946126.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Dillon CONTACT PERSON: Barbara C. Lamoureux Pasco MIC and MIC/ID Panels TRADE NAME OF DEVICE: Antimicrobial Susceptibility Test COMMON NAME : Class II Antimicrobial Susceptibility CLASSIFICATION NAME: Test Microbiology Panel #83 ## SUBSTANTIAL EQUIVALENCE: In review of previous 510(k) notifications for the Pasco MIC and MIC/ID panels (most recently K980955 May 18, 1998 RE: Trovafloxacin; K974362, February 12, 1998 RE: Cefepime; K973317, November 14, 1997 RE: Cefpodoxime; K973695, November 5, 1997 RE: Meropenem; K972567, August 20,1997 RE: Sparfloxacin; K971951, August 15, 1997 RE: Levofloxacin; and K946126, January 17, 1995 Detection of Resistant pneumococci), the FDA has determined RE : the Pasco panels to be substantially equivalent to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments. The term "substantial equivalence" as used in this 510(k) notification is limited to the definition of substantial equivalence as found in the Federal Food, Drug, and Cosmetic Act, as amended and as applied under 21 CFR 807, Subpart E under which a device can be marketed without pre-market approval or reclassification. A determination of substantial equivalency under this notification is not intended to have any bearing whatsoever on the resolution of patent infringement suits or any other patent matters. No statements related to, or in support of substantial equivalence herein shall be construed as an admission against interest under the US Patent Laws or their application by the courts. ## DESCRIPTION OF THE DEVICE: Varying concentrations of antimicrobial agents (usually in twofold dilutions) are dispensed into the Pasco panels and the panels are then frozen. Panels are thawed prior to use, inoculated with the test organisms, incubated the traditional 16-24 hours and then observed for visible growth or color changes as described in the package insert. {1}------------------------------------------------ 3) The lowest concentration of each antimicrobial agent with no apparent visible growth of the test organism is recorded as the minimum inhibitory concentration (MIC). Changes in pH and production of specific metabolites from growth in biochemical substrates are interpreted as described in the package insert for conventional tubed media. INTENDED USE FOR THE PASCO MIC AND MIC/ID PANELS: PASCO MIC AND MIC/ID PANELS are used for quantitatively measuring (with the exception of the Breakpoint/ID panel which provides qualitative measurement or category results) the susceptibility of rapidly growing aerobic and facultative anaerobic bacterial pathogens to a battery of antimicrobial agents and determining the biochemical identification of those organisms. SUMMARY/CONCLUSION OF SUBSTANTIAL EQUIVALENCE TESTING: Test panels containing Minocycline at concentrations ranging from 32 to 0.03 mcg/ml were prepared in-house at Pasco using routine manufacturing procedures. Comparative testing of the Pasco test panel to a reference panel was performed at two sites using CDC challenge strains and clinical Isolates. Test results of the 334 gram-negative Strains demonstrated acceptable Essential Agreement (EA) of 99.8% upon initial testing and 100% upon retesting. No Major (M) or Very Major (VM) errors were observed. Category Agreement (CA) was 100% with twenty-one random minor errors noted. Test results of the gram-positive Strains demonstrated acceptable Essential Agreement (EA) of 100%. No Major (M) or Very Major (VM) errors were observed. Category Agreement (CA) was 100% with six random minor errors noted. QC endpoints from both the reference and Pasco panels throughout testing were within the recommended acceptable ranges listed in the product information and NCCLS with the exception of 7 endpoints which were within 1 dilution of the mode for the strains tested. Reproducibility testing of 12 organisms at each site provided 7 onscale endpoints. Overall reproducibility data demonstrated 99.5% within the acceptable plus or minus 1 dilution. The results of the clinical testing, reproducibility testing and QC performance testing supports Substantial Equivalence as outlined in the FDA draft document "Review Criteria For Assessment Of Antimicrobial Susceptibility Devices" (May 1991). {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.

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 requirement, 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. {3}------------------------------------------------ ## Page 2 Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization.
