Strategic Imperative: The MCaST Initiative#
What is Quest Diagnostics' MCaST blood test and its strategic importance?#
Quest Diagnostics' MCaST blood test is a pioneering effort to provide early detection and risk stratification for multiple cancers, including colorectal, lung, breast, and pancreatic cancers, among others. Unlike many emerging liquid biopsy tests that primarily focus on circulating tumor DNA (ctDNA), MCaST leverages the analysis of circulating protein biomarkers. This distinction is key: protein biomarkers can potentially offer a different window into cancer presence and risk, complementing or even surpassing DNA-based methods in certain contexts by detecting changes that may occur earlier or be more prevalent in specific cancer types. The collaboration with MD Anderson Cancer Center, a globally recognized leader in oncology research, provides significant scientific validation and clinical expertise to the development process, bolstering the test's credibility and potential for widespread adoption upon its anticipated commercialization in North America by 2026 Quest Diagnostics Official Website.
