Tailwinds for Quest Diagnostics

Growth Momentum in the Base Business Continues: Quest Diagnostics has been experiencing robust volume growth in its core business (excluding COVID-19 Testing), banking on the growth of new physician and hospital customers, a more favorable test mix with increased use of advanced diagnostics and acquisitions. The Hospital Lab Services is posting growth above historical levels, supported by dynamics that lead to strong continued demand for reference testing. In the third quarter of 2024, the company delivered strong volume and revenue growth from its Medicare Advantage plans.

Quest Diagnostics is well-positioned to capitalize on the sustained high healthcare utilization rates and continue driving new customer growth.
A strong consumer focus is helping it capture growing opportunities in consumer-initiated testing and demand for expanded access to basic health care. Its repeat customer rate has surged 30% from less than 10% two years ago, reflecting demand for comprehensive health, chronic disease and STI (sexually transmitted infection) testing.

Strong Potential of Advanced Diagnostics: Quest Diagnostics’ expanding portfolio of advanced diagnostics is driving robust adoption, leading to a favorable test mix and growth in test per requisition. Within brain health, AD-Detect blood-based Alzheimer’s disease testing has been the key driver, while women’s health is gaining from prenatal and hereditary genetic testing, consistent with recent quarters. Testing demand for genital tract infections, including several STIs, also remains strong.

In July 2024, Quest Diagnostics teamed up with Becton, Dickinson and Company to create flow cytometry-based companion diagnostics (CDx) for the selection of the best treatment for patients with cancer and other diseases. The acquisition of Haystack Oncology positions the company in the higher-growth clinical area of ctDNA (Circulating tumor DNA) solid-tumor MRD (minimal residual disease) testing.
