VITEK® 2 Gram Positive Inducible Clindamycin Resistance is designed for antimicrobial susceptibility testing of Staphylococcus species. VITEK 2 Gram Positive Inducible Clindamycin Resistance is a qualitative test. It is intended for use with the VITEK 2 and VITEK 2 Compact Systems as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents.
The VITEK® 2 Antimicrobial Susceptibility Test (AST) is intended to be used with the VITEK® 2 and VITEK® 2 Compact Systems for the automated quantitative or qualitative susceptibility testing of isolated colonies for the most clinically significant aerobic gramnegative bacilli, Staphylococcus spp., Enterococcus spp., Streptococcus agalactiae, and S. pneumoniae.
VITEK® 2 Gram Positive Inducible Clindamycin Resistance is a qualitative test designed for antimicrobial susceptibility testing of Staphylococcus species. A positive ICR test is indicative of inducible MLS, resistance, which confers resistance to macrolides, lincosamides, and type B inducible MLS, resistance, which confers resistance to macrolides, and VITEK® 2 Co laboratory aid in the determination of in vitro susceptibility to antimicrobial agents. The antimicrobial presented in VITEK 2 AST Cards is in concentrations equivalent by efficacy to standard method concentrations in mcg/ml. The VITEK 2 AST Cards are essentially miniaturized versions of the doubling dilution technique for determining the minimum inhibitory concentration (MIC) microdilution methodology.
The bacterial isolate to be tested is diluted to a standardized concentration in 0.45% - 0.5% saline before being used to rehydrate the antimicrobial medium within the card. The VITEK 2 System belomatically fills, seals and places the card into the incubator/reader. The VITEK 2 Compact has a manual filling and sealing operation. The VITEK 2 monitors the growth of each well in the card over a defined period of time (up to 18 hours). At the completion of the incubation cycle, a report is over a delined pend of the (up to To Tronice). It the interpretive category result for each antibiotic contained on the card.

The Premarket Notification (510[k]) presents data in support of VITEK 2 Gram Positive Inducible Clindamycin Resistance. An external evaluation was conducted with fresh and stock clinical isolates and stock challenge strains. The external evaluations were designed to confirm the acceptability of VITEK 2 Gram Positive Inducible Clindamycin Resistance by comparing its performance with the CLSI Disk Approximation Test reference method. The data is representative of performance on both the VITEK 2 and VITEK 2 Compact instrument platforms, as evidenced in the AST equivalency study presented in the VITEK 2 Compact 510(k), K050002. VITEK 2 Gram Positive Inducible Clindamycin Resistance demonstrated acceptable performance of 99.3% overall Category Agreement. Reproducibility and Quality Control demonstrated acceptable results.
*Note: This device clinical trial was initiated prior to the March 5, 2007 issuance of the revised guidance, which is why the older guidance document is cited.

§ 866.1645 Fully automated short-term incubation cycle antimicrobial susceptibility system.
(a)
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.(b)
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.”
