Quest Diagnostics integrates cancer testing into Flatiron's OncoEMR for 4,700 US clinicians in pilot with American Oncology Network.

Quest Diagnostics has integrated its advanced cancer tests, including the Haystack MRD ctDNA test and Comprehensive Genomic Profiling, into Flatiron Health's OncoEMR electronic health record system. This pilot program with American Oncology Network (AON) enables nearly 200 AON sites and 4,700 clinicians to order and receive test results more efficiently within their existing workflows. The integration simplifies complex molecular oncology testing, helping physicians make faster, informed treatment decisions. Quest plans to expand this integration nationwide later in 2026, aiming to improve cancer care accessibility and reduce administrative burdens for community oncology providers.
