Input: standardized suspension of bacterial colonies grown on solid media. Process: inoculation of panels; incubation at 35°C for 4.5–18 hours in WalkAway SI/40/96 systems. Output: Minimum Inhibitory Concentration (MIC) determined by lowest concentration inhibiting growth. Used in clinical microbiology laboratories; operated by laboratory technicians. Results interpreted by clinicians to guide antimicrobial therapy for Gram-negative infections. ## Clinical Evidence Bench testing only. Evaluation compared performance of the rapID/S plus Gram-Negative Panel with Trimethoprim/Sulfamethoxazole against NCCLS frozen reference panels using fresh/stock clinical isolates and challenge strains. Results showed 97.5% overall Essential Agreement. Reproducibility and precision testing confirmed acceptable performance using the WalkAway system and turbidity inoculum preparation. ## Technological Characteristics Miniaturized broth microdilution panels; Mueller-Hinton Broth; dried antimicrobial agents. Incubation at 35°C. Automated reading via WalkAway SI/40/96 systems. Connectivity: Integrated with WalkAway instrument software. Sterilization: Not specified. ## Regulatory Identification A fully automated short-term incubation cycle antimicrobial susceptibility system is a device that incorporates concentrations of antimicrobial agents into a system for the purpose of determining in vitro susceptibility of bacterial pathogens isolated from clinical specimens. Test results obtained from short-term (less than 16 hours) incubation are used to determine the antimicrobial agent of choice to treat bacterial diseases. ## Special Controls *Classification.* Class II (special controls). The special control for this device is FDA's guidance document entitled “Class II Special Controls Guidance Document: Antimicrobial Susceptibility Test (AST) Systems; Guidance for Industry and FDA.” ## Predicate Devices - MicroScan Dried Gram Negative MIC/Combo Panels ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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) that do not require approval of a premarket approval (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 additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. {1}------------------------------------------------ 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 Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to continue 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.

The MicroScan® rapID/S plus ™ Cram-Negative MIC/Combo Panels are read on the WalkAway 57 System or equivalent (upgraded WalkAway® 40 or WalkAway® 96 instruments). The antimicrobial susceptibility tests are miniaturizations of the broth dilution susceptibility test that have been diluted in Mueller-Hinton Broth to concentrations bridging the range of clinical interest and are presented in micro-titer wells in dried form. rapID/S plus™ panels are inoculated with a standardized suspension of the organism and incubated at 35℃ in the WalkAway® SI System or equivalent for 4.5 - 18 hours. The minimum inhibitory concentration (MIC) for the test organism is determined by the lowest antimicrobial concentration showing inhibition of growth. The proposed MicroScan® rapID/S plus™ Gram-Negative MIC/Combo Panel demonstrated substantially equivalent performance when compared with an NCCLS frozen Reference Panel, as defined in the FDA DRAFT document "Guidance on Review Criteria for Assessment of Antimicrobial Susceptibility Devices" dated March 8, 2000. The Premarket Notification (510[k]) presents data in support of the MicroScan® rapID/S plus™ Gram-Negative MIC/Combo Panel with Trimethoprim/Sulfamethoxazole. The external evaluation was conducted with fresh and stock Efficacy isolates and stock Challenge strains. The external evaluations were designed to confirm the acceptability of the proposed rapID/S plus ™ Gram-Negative Panel by comparing its performance with an NCCLS frozen Reference panel. Challenge strains were compared to Expected Results determined prior to the evaluation. The rapID/S plus™ Gram-Negative Panel demonstrated acceptable performance with an overall Essential Agreement of 97.5% for Trimethoprim/Sulfamethoxazole when compared with the frozen Reference panel. Instrument reproducibility testing demonstrated acceptable reproducibility and precision with Trimethoprim/Sulfamethoxazole with Turbidity inoculum preparation method and the WalkAway® System or equivalent (upgraded WalkAway® 40 or WalkAway® 96 instruments). Quality Control testing demonstrated acceptable results for Trimethoprim/Sulfamethoxazole. --- **Source:** [https://fda-staging.innolitics.com/device/K020248](https://fda-staging.innolitics.com/device/K020248) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
