Individuals in the U.S. can now add Humanity Biological Age's lab-informed insights to select health profile tests purchased through Quest's consumer-initiated testing platform

LONDON, Aug. 25, 2026 /PRNewswire/ -- Humanity Health Inc. ("Humanity"), the longevity science company, and Quest Diagnostics (NYSE: DGX) today announced that Humanity Biological Age, Humanity's scientifically validated model for measuring biological age from biomarker lab test results, is now available in the United States for the first time through questhealth.com, Quest's consumer-initiated testing platform.

Individuals now have the option to select the Humanity Biological Age add-on when purchasing select health profile tests from questhealth.com including Elite Health Profile, Men's and Women's Comprehensive Health Profiles, and Fitness Profile — Elite, with no additional blood draw needed. After completing a health profile sample collection at one of Quest's approximately 2,000 patient service centers across the U.S., customers can upload their lab results from Quest directly to Humanity's platform. The Humanity Biological Age add-on will cost $29 at questhealth.com.

The Humanity Biological Age report gives individuals a scientifically validated measure of biological age from their lab results, alongside their age difference, which shows how that estimate compares with their chronological age. For those who test more than once, it also shows how that difference is trending over time. The report identifies which of the body's systems are influencing the result, including cardiovascular, metabolic, liver, kidney, blood, immune and inflammatory, hormonal, and bone and mineral health. Each is expressed as the number of years it adds to or subtracts from the biological age result. The report also includes general information on lifestyle actions associated with biological age.Biological age is a measure of how well a person's body is functioning, rather than simply how many years they have lived. Developed with Imperial College London, Humanity Biological Age turns the biomarkers measured in routine blood tests into a single, easy-to-understand, biological age number that individuals can act on and track over time.
