Inspired by a personal health scare, PreciseMDX co-founder and Silicon Valley tech veteran Guy Livneh was determined to dramatically improve the entire testing journey for labs, providers and patients. It took months for Guy’s care team to not only get access to the right kind of tests, but to receive the results critical to his path to recovery. It shouldn’t have to be this difficult for anyone, Guy believed.
With the COVID pandemic elevating the urgency for labs and providers to streamline and expedite testing for patients, Guy and his business partner of 30 years Mark Dorner jumped on the opportunity to help labs digitally transform the entire journey, making it easier to provide customers with access to more tests for more patients, with faster results.
Just one year later, PreciseMDX’s best-in-class platform integrates labs, medical device manufacturers, shipping and fulfillment companies, clearing houses, state authorities and biotech companies for a new era of digital connectivity, giving way to happier patients and healthier bottom lines.
“We remove all the complexities of launching a complete digital health environment for diagnostic testing and population health management, allowing labs to deliver a seamless consumer experience that patients expect and deserve”
