Indications for Use

MicroScan® Synergies plus™ Gram-Negative MIC/Combo Panel is used to determine quantitative and/or qualitative antimicrobial agent susceptibility of colonies grown on solid media of rapidly growing aerobic and facultative anaerobic Gram-Negative bacilli (Enterobacteriaceae, glucose non-fermenters, and non-Enterobacteriaceae glucose fermenters. After inoculation, panels are read on the WalkAway® SI System or equivalent (upgraded WalkAway® 40 or WalkAway® 96) according to the Package Insert.

Device Story

MicroScan Synergies plus Gram-Negative MIC/Combo Panels are miniaturized broth dilution susceptibility tests. Panels contain antimicrobial agents (Piperacillin) in dried form within micro-titer wells. Clinical laboratory technicians inoculate panels with standardized bacterial suspensions; panels are incubated at 35°C within the WalkAway SI System (or upgraded WalkAway 40/96). The system monitors growth inhibition; the lowest concentration of antimicrobial showing inhibition determines the Minimum Inhibitory Concentration (MIC). Results are used by clinicians to guide antibiotic therapy for Gram-negative infections. The device provides quantitative/qualitative susceptibility data to assist in selecting effective antimicrobial treatments.

Clinical Evidence

Bench testing only. Evaluation used fresh clinical isolates and stock challenge strains compared against an NCCLS frozen reference panel. Essential agreement for Piperacillin was 94.4%. Reproducibility and precision were validated using the WalkAway SI System with turbidity inoculum preparation. Quality control testing met acceptance criteria.

Technological Characteristics

Micro-titer plate format containing dried antimicrobial agents. Principle: broth microdilution. Energy source: electrical (WalkAway instrument). Connectivity: integrated with WalkAway SI System (or upgraded WalkAway 40/96). Sterilization: N/A (in vitro diagnostic).

Indications for Use

Indicated for determining antimicrobial susceptibility of rapidly growing aerobic and facultative anaerobic Gram-Negative bacilli (Enterobacteriaceae, glucose non-fermenters, and non-Enterobacteriaceae glucose fermenters) isolated from clinical specimens. Specific organisms include E. coli, Enterobacter spp., Klebsiella spp. (excluding K. oxytoca), Proteus spp. (excluding P. mirabilis), Providencia rettgeri, Pseudomonas spp., Serratia spp., Shigella spp., Salmonella spp., and Yersinia spp. Contraindicated for Acinetobacter spp., Citrobacter spp., Klebsiella oxytoca, Morganella morganii, and Proteus mirabilis.

Regulatory Classification

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.”

Dear Mr. Eusebio:

This letter corrects our substantially equivalent letter of April 22, 2002, regarding the trade name which was changed to MicroScan® Synergies Plus to better reflect the intended use of the device.

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.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally Part 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]. Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers, International and Consumer Assistance at their toll free number [phone] or at [phone] or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html.
