VITEK® 2 AST-Gram Negative Imipenem/Relebactam is designed for antimicrobial

susceptibility testing of Gram Negative bacilli and 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. VITEK® 2 AST-Gram Negative

Imipenem/Relebactam is a quantitative test. Imipenem/Relebactam has been shown to be

active against most strains of the microorganisms listed below, according to the FDA label

for this antimicrobial.

Active in vitro and in clinical infections:

Klebsiella (Enterobacter) aerogenes

Enterobacter cloacae

Escherichia coli

Klebsiella pneumoniae

Pseudomonas aeruginosa

Citrobacter freundii

Klebsiella oxytoca

In vitro data are available, but clinical significance is unknown

Citrobacter koseri

Enterobacter asburiae

The VITEK® 2 Gram-Negative Susceptibility Card is intended for use with the VITEK® 2

Systems in clinical laboratories as an in vitro test to determine the susceptibility of clinically

significant aerobic Gram-negative bacilli to antimicrobial agents when used as instructed.

Indications for use as stated in the FDA summary.
