What we do

Making the lifesaving advanced diagnostics more accessible through Quest Advanced^®

By combining our national footprint and innovations in genomics and molecular testing, we’re making it easier for providers and hospitals to bring advanced diagnostics into their daily practice to save lives. The power of Quest Advanced doesn’t stop at the broad portfolio of tests, its true strength sits in the clinical support and service that ensures providers have the confidence that they can do what’s best for their patients.

Building IT and data analytics tools that make healthcare work better and insights go farther

As the leading national provider of diagnostics testing, we have a tremendous wealth of data that are instrumental in enhancing healthcare. Whether it’s improving outcomes and reducing costs by helping providers utilize the right test at the right time, or by identifying gaps in care to ensure that people are getting the care they need, we’re at the forefront of turning data into meaningful results. 

Behind this data is our Quanum^® suite of technology solutions that enables secure and seamless ordering, processing, and sharing of test results to ensure that healthcare providers can access information easily and quickly make important care decisions.

Creating the lab operations and infrastructure of the future

Taking action towards health equity

The COVID-19 pandemic laid bare the health disparities that have been growing within our society for all to see. Infection rates and death rates disproportionately impact people of color, as well as those living in communities of low-income households. Recognizing the need to address health inequality more broadly and to take action to provide COVID-19 testing services, Quest Diagnostics and the Quest Diagnostics Foundation committed more than $100 million to launch Quest for Health Equity.
