  • 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

Quality Control:
This module provides your laboratory with the ability to store the VITEK® 2 Card Quality Control results and track quality control performance. Cumulative Quality Control reports are easily generated and can list all results with the exceptions flagged or list exceptions only.

Bi-directional Computer Interface (BCI):
With the Bi-directional Computer Interface (BCI) package, the VITEK 2 can receive patient information directly from the Laboratory Information System and transmit microbiology test data directly to it. This minimizes keystrokes and data transcription errors while automatically uploading test data into the LIS. BCI plays an integrated role in providing rapid reporting of identification and antimicrobial susceptibility results.
