Quest Diagnostics Advances Cancer and Alzheimer's Diagnostics Amid Strong Q1 2025 Performance#
Quest Diagnostics Incorporated (DGX is spearheading innovation in medical diagnostics through its recent strategic developments, notably the Multi-Cancer Stratification Test (MCaST) in partnership with MD Anderson Cancer Center and the AD-DETECT™ Alzheimer's diagnostic platform. These advancements coincide with robust financial results in Q1 2025, reinforcing the company's leadership in precision diagnostics and positioning it for sustained growth in evolving healthcare markets.
Strategic Breakthrough: MCaST Multi-Cancer Risk Assessment#
Quest Diagnostics' collaboration with MD Anderson has produced MCaST, a novel blood test designed to assess risk across multiple cancers by detecting circulating protein biomarkers. This test targets nine cancers responsible for approximately 85% of U.S. diagnoses, including colorectal, lung, breast, and pancreatic cancers. Unlike DNA methylation-based diagnostics such as Galleri, which identify existing cancer signals, MCaST aims to stratify patients based on risk, enabling earlier interventions and tailored screening protocols.
MCaST leverages advanced proteomics technologies—liquid chromatography and mass spectrometry—to quantify specific protein biomarkers. This approach offers a non-invasive, cost-effective alternative to conventional cancer detection methods and addresses a critical gap in oncology screening by focusing on risk rather than presence. Commercial launch is anticipated in North America by 2026, pending validation, underscoring Quest's commitment to integrating cutting-edge science into clinical practice Quest Diagnostics Newsroom.
Expanding Neurological Diagnostics with AD-DETECT™#
In the neurodegenerative disease arena, Quest has introduced AD-DETECT™, a blood-based test for early Alzheimer's detection. The test measures plasma amyloid beta 42/40 ratios and phosphorylated tau (p-tau217), biomarkers closely linked to amyloid pathology in the brain. Recent data report 91% sensitivity and specificity, positioning AD-DETECT™ as a practical alternative to more invasive and expensive procedures like PET scans or cerebrospinal fluid analysis Quest Diagnostics - Alzheimer's Diagnostics.
AD-DETECT™ is currently available nationwide through physician channels, with ongoing validation and efforts to secure reimbursement pathways. This product exemplifies Quest's strategy to broaden its diagnostics portfolio into high-value, personalized medicine sectors.
Robust Financial Performance Underpins Strategic Initiatives#
Quest Diagnostics reported a Q1 2025 EPS of $2.21, surpassing analyst estimates of $2.15, alongside revenues of approximately $2.7 billion, reflecting a +12.09% year-over-year growth that outpaces the industry average of 5.85% Morganville Coop. This strong top-line performance is supported by increased testing volumes, including growth in high-margin oncology and neurological tests.
The company reaffirmed its full-year EPS guidance of $9.55 to $9.80, with consensus estimates projecting $9.70, an 8.6% increase over 2024. This optimism is underpinned by strategic acquisitions, new product launches, and ongoing demand in hospital partnerships.
