Device Description
VITEK® 2 Gram Positive Erythromycin for Streptococcus pneumoniae is designed for antimicrobial susceptibility testing of Streptococus 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 mog/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.
More Information

No
The description focuses on automated quantitative/qualitative susceptibility testing using a miniaturized doubling dilution technique and monitoring growth over time. There is no mention of AI or ML algorithms being used for interpretation or analysis.

No.
Explanation: The device is a diagnostic tool used to determine the susceptibility of bacteria to antimicrobial agents, aiding in treatment decisions but not directly providing therapy.

Yes

Explanation: The device is used for automated quantitative or qualitative susceptibility testing of isolated colonies to antimicrobial agents, which aids in determining the appropriate treatment for infections. This directly contributes to diagnosing the susceptibility of bacteria to drugs, which falls under the definition of a diagnostic device.

No

The device description clearly outlines physical components like "VITEK 2 AST Cards" containing antimicrobial medium and mentions the "VITEK 2 System" and "VITEK 2 Compact" instruments which are hardware. The submission is for an addition of interpretive criteria, which is software-related, but the core device involves hardware for testing.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states it is for "in vitro susceptibility testing of isolated colonies" and acts as a "laboratory aid in the determination of in vitro susceptibility to antimicrobial agents." This directly aligns with the definition of an in vitro diagnostic device, which is used to examine specimens taken from the human body to provide information for diagnosis, treatment, or prevention of disease.
  • Device Description: The description details how the device tests bacterial isolates in a laboratory setting by rehydrating antimicrobial medium within a card and monitoring growth. This process is performed in vitro (outside the body).
  • Performance Studies: The performance studies compare the device's performance to a "CLSI broth microdilution reference method," which is a standard laboratory technique for in vitro susceptibility testing.

All these points confirm that the VITEK® 2 Gram Positive Erythromycin for Streptococcus pneumoniae is designed and used for testing biological samples in vitro to aid in clinical decision-making, making it an IVD.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

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 Erythromycin 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 Erythromycin for Streptococcus pneumoniae demonstrated acceptable performance of 98.4% overall Category Agreement. Reproducibility and Quality Control demonstrated acceptable results.

(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.”

. A 510(k) for VITEK 2 Gram Positive Erythromycin for Streptococcus pneumoniae (K063492) was cleared by FDA on 21Dec2006. This premarket notification is for the same AST with the only modification being a software algorithm change to utilize the existing FDA intermediate breakpoint for Erythromycin and S. pneumoniae, and thereby lift the VITEK 2 Systems limitation regarding the inability of the Systems to report intermediate results for Erythromycin and S. pneumoniae strains. There has been no change to the VITEK 2 AST-GP Erythromcyin for S. pneumoniae formulation since K063492 was cleared. The analysis was modified to conform to standard practice of reporting results for all available FDA breakpoints for an antibiotic/organism combination. The clinical trial data submitted as part of K063492 was re-analyzed using the modified algorithm analysis. There was no new clinical data gathered for this 510(k) notification. The modified algorithm for this AST will be included in a future software release (VITEK 2 Systems software version PC 4.01).
