Quest Diagnostics Incorporated : 2023 Highlights

2023 Corporate Responsibility Report

Quest works across the healthcare ecosystem to create a healthier world, one life at a time. Whether it's fostering a positive experience in our patient service centers, helping hospitals operate more efficiently, or expanding our testing portfolio, our ~48,000 colleagues work together every day to care for our patients, customers, and one another.

In 2023, we made progress toward our Environmental, Social, and Governance (ESG) goals. We developed new tests to advance early disease detection and expanded access to our solutions through various efforts, including our Quest for Health Equity initiative. We relaunched our HealthyQuest program, to further support the health and well-being of our colleagues, and formed collaborations to improve population health.
