Intended Use

VITEK® 2 Gram Positive Meropenem for Streptococcus pneumoniae is designed for antimicrobial susceptibility testing of Streptococcus pneumoniae. VITEK 2 Gram Positive Meropenem for Streptococcus pneumoniae is a quantitative 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.

Device Story

VITEK® 2 system performs automated antimicrobial susceptibility testing (AST). Input: pure culture of Streptococcus pneumoniae suspended in saline (0.5 McFarland standard). Process: organism suspension loaded into VITEK® 2 cassette; instrument automatically fills, seals, and transfers cards to incubator (35.5°C). System monitors bacterial growth via fluorescence-based optical scanning every 15 minutes; detects activity of specific surface enzymes. Algorithm uses discriminant analysis of growth patterns to calculate MIC. Output: quantitative MIC and qualitative susceptibility interpretation. Used in clinical laboratories by trained personnel. Benefits: provides rapid, automated determination of antibiotic susceptibility to guide clinical treatment decisions.

Clinical Evidence

External evaluation conducted using fresh and stock clinical isolates and stock challenge strains. Performance compared to CLSI broth microdilution reference method. Results demonstrated 97.3% overall Essential Agreement and 92.9% overall Category Agreement. Reproducibility and Quality Control testing yielded acceptable results.

Technological Characteristics

Miniaturized AST card containing antimicrobial medium; concentrations equivalent to standard broth microdilution. Automated incubation and optical monitoring system. Compatible with VITEK 2 and VITEK 2 Compact platforms. Quantitative MIC determination.

Indications for Use

Indicated for testing Streptococcus pneumoniae with Meropenem at 0.125-1 µg/mL using VITEK® 2 GP panel Susceptibility Plates (calling range ≤ 0.06- ≥ 4 µg/mL). For prescription use only.

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.”

C. VITEK® 2 Gram Positive Meropenem for Streptococcus pneumoniae is designed for antimicrobial susceptibility testing of Streptococcus pneumoniae. 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 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% saline before being used to rehydrate the antimicrobial medium within the card. The VITEK 2 System automatically 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 generated that contains the MIC value along with the interpretive category result for each antibiotic contained on the card. VITEK 2 Gram Positive Meropenem for Streptococcus pneumoniae demonstrated substantially equivalent performance when compared with the CLSI broth microdilution reference method, as {1}------------------------------------------------ defined in the FDA Class II Special Controls Guidance Document: Antimicrobial Susceptibility Test (AST) Systems; Guidance for Industry and FDA, Issued Feb. 5, 2003. The Premarket Notification (510[k]) presents data in support of VITEK 2 Gram Positive Meropenem for Streptococcus pneumoniae. 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 Meropenem for Streptococcus pneumoniae by comparing its performance with the CLSI broth microdilution 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 Amoxicillin for Streptococcus pneumoniae demonstrated acceptable performance of 97.3% overall Essential Agreement and 92.9% overall Category Agreement. Reproducibility and Quality Control demonstrated acceptable results. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
