Performance, connectivity, confidence

The cobas® Liat® System is powered by a versatile communication engine to securely transmit data across your health network, supported by the most common standardized protocols for lab information systems (LIS) and data management systems (DMS) or middleware.

Communicate results, manage users and fully integrate all devices by connecting the cobas® Liat® System to a modularized point-of-care management software solution for the future - cobas® infinity POC solution.

This solution has been designed centered around the user to:

  • Centralize and optimize workflows for point-of-care coordinators and supporting functions
  • Improve quality of care and data delivery
  • Reduce resources needed for managing the system and give time back for other activities


The unique combination of cobas® infinity POC, together with the cobas® Liat® System and its growing menu of assays, forms the revolutionary total point-of-care PCR solution.
