Achieve absolute automation from sample tube onward

Molecular Testing in 3 easy steps


Flexible sample loading, processing and testing

  • Allows for mixed batching, making it possible to performup to 3 tests in the same run with no pre-sorting required
  • Optimizes sample utilization, allowing you to process up to 3 different tests from the menu using a single patient sample
  • Simplifies testing workflow by using universal processes, consumables and reagents so you can run any test when you want
  • Offers a broad and expanding assay menu to meet your needs today and in the future
  • A dedicated priority lane enables fast and easy handling of high-priority samples

Transform your testing experience

Offering highly efficient workflows from sample processing to result interpretation, the cobas® 8800 System puts the future of molecular testing in your hands. Our broad assay menu is held to the rigorous performance standards you expect from Roche, and our real-time PCR technology delivers reliable results every time.
