Designed for patient icon

Designed for the patient, optimized for the lab

The cobas® eplex system sample-to-answer capabilities integrate the whole process from order-to-report to better realize the patient and laboratory benefits of rapid, multiplex molecular diagnostics. 

The ePlex® System offers many unique solutions that were thoughtfully engineered to address the biggest challenges you face in the clinical laboratory and to support hospital systems in delivering patient centered, value-based care.

Reduce medical errors icon

Designed for the patient to reduce avoidable medical errors

Preventable medical errors are now the third leading cause of death in the United States at more than 250,000 per year.1 Automating information transfer has been shown to be effective in reducing many common errors, including patient identity checking and order transcription.2

The ePlex® System is uniquely designed with patient safety features in mind so that labs and physicians can have the confidence that they have the right patient, with the right test, and the right result, every time.

  • Reduce the chance of pre-analytical errors with less than 1 minute hands-on time and guided workflows

  • Transcription errors can be eliminated in both order entry and result reporting with bi-directional LIS

Maximize lab effciency icon

Optimized for the lab to maximize lab efficiency by reducing administrative overhead

Monitoring and reporting quality control testing is both a requirement and a best practice to ensure accuracy of patient results and compliance with lab standards. With on-board QC tracking capabilities and safeguards, you can not only run controls when required, you can also easily track and report compliance.

In addition to automated control tracking, the ePlex® System provides the following compliance and data management tools:

  • Integrated data analytics to easily monitor lab performance
  • On-demand epidemiology reports for export and simplified analysis
  • Fully configurable, auto-release of test results

All of these unique capabilities of the ePlex® System allow you to reduce the time spent on routine administrative tasks and focus your limited resources on high-value activities that impact patient care and the bottom line.
