Roche Tissue Diagnostics

Founded as Ventana Medical Systems, Inc., in 1985 by University of Arizona pathologist Dr. Thomas Grogan, the company was acquired by Roche in 2008. Known today as Roche Tissue Diagnostics, we have revolutionized cancer diagnostics worldwide through state-of-the-art  testing automation. We provide more than 250 cancer tests and associated instruments, making us the leading global supplier of cancer diagnostic systems to the pathology market.

We are improving patient care through tests that determine which patients are most likely to benefit from specific therapies. Through companion diagnostics, we are linking the most accurate diagnosis with the most targeted and relevant therapeutic available for each patient. We partner with Roche Pharma and other pharmaceutical companies to develop predictive diagnostics that provide patients with personalized treatment options, such as immunotherapies which encourage the body’s immune system to target and kill cancer cells.

Through excellence and innovation in science and engineering, our people are leading the discovery, development and delivery of diagnostic systems and tissue-based cancer tests that are guiding the future of healthcare. This culture of constant innovation at Roche Tissue Diagnostics fuels our vision: to empower our customers by providing the highest quality, most innovative cancer diagnostic solutions. We are passionate in our pursuit of diagnostic solutions that improve the practice of medicine because when we empower pathology professionals, we brighten the outlook for patients.
