Quest Diagnostics IncorporatedNew York State approval enables nationwide use of Haystack MRD test.
Quest Diagnostics received New York State approval for its Haystack MRD liquid biopsy test, enabling nationwide use for detecting residual or recurrent cancer. The approval follows published research indicating the test's high sensitivity for minimal residual disease monitoring. Quest Diagnostics also entered a national partnership with Attunio Health to support an AI-powered precision psychiatry platform, providing scalable laboratory infrastructure for mental health diagnostics across the United States. The Haystack MRD test now has regulatory clearance across all 50 states and clinical backing from major centers such as Memorial Sloan Kettering and City of Hope, positioning Quest to compete more directly with other cancer monitoring players like Guardant Health and Exact Sciences. On the mental health side, serving as the lab backbone for an AI-powered precision psychiatry platform gives Quest a role in turning biological markers into routine psychiatric decision support, an area where competitors such as Labcorp and Mayo Clinic Laboratories are also active.
