Vitek® 2: Healthcare

Vitek® 2: Healthcare

The VITEK 2 system has everything healthcare laboratories need for fast, accurate microbial identification, and antibiotic susceptibility testing.


The innovative VITEK 2 microbial identification system includes an expanded identification database, the most automated platform available, rapid results, improved confidence, with minimal training time.

The VITEK 2 system next-generation platform provides greater automation while increasing safety and eliminating repetitive manual operations. The rapid response time means results can be provided more quickly than with manual microbial identification techniques.

VITEK 2: Overview

The VITEK 2 system offers:

  • Windows® based, user-friendly software
  • bi-directional interface
  • epidemiology report module
  • ADVANCED EXPERT SYSTEM™ (AES) software for on-line result validation
  • a new generation of test cards
  • a comprehensive database

Automated systems:

  • VITEK® 2 XL
  • VITEK® 2 60
  • VITEK® 2 Compact 60
  • VITEK® 2 Compact 30
  • VITEK® 2 Compact 15


  • Microbial Identification - bacteria and yeast identification (ID)
  • Antibiotic susceptibility testing (AST) and resistance mechanism detection
  • Epidemiologic trending and reporting

Features and Benefits

The VITEK 2 system can:

  • Reduce time to microbial identification and antibiotic susceptibility testing results
  • Offer an extensive identification and susceptibility menu
  • Reduce waste with a miniaturized card-format that measures 10 cm x 6 cm x 0.5 cm and weighs only 16 grams
  • Meet the needs of any size laboratory

VITEK 2 systems use Advanced Colorimetry™, an identification technology that enables identification of routine clinical isolates. Advanced Colorimetry provides:

  • High discrimination between species
  • Low rate of multiple choice and misidentified species
  • Minimal number of off-line tests

The system includes an ADVANCED EXPERT SYSTEM (AES) that analyzes MIC patterns and detects phenotypes for most organisms tested. This helps optimize laboratory efficiency for lean laboratory management. Rapid results allow clinicians to discontinue empiric therapy and prescribe targeted therapy, resulting in improved patient outcomes and enhanced antibiotic stewardship.

With its ability to provide accurate “fingerprint” recognition of bacterial resistance mechanisms and phenotypes, the ADVANCED EXPERT SYSTEM (AES) is a critical component of VITEK 2 technology.

VITEK 2 technology with the ADVANCED EXPERT SYSTEM offers:

  • Knowledge base developed from >100,000 references
  • >2,000 described phenotypes
  • >20,000 MIC distributions
  • >100 resistance mechanisms detected
  • >99 organisms
  • On average, provides a resulting range of five to seven MIC doubling dilutions per antibiotic
  • Extended MIC range to enable low-level resistance detection
  • Resistance-oriented results that highlight unusual phenotypes
  • Deduced antibiotic results to meet formulary requirements
  • Checks every result every time
