The global biomarker market, valued at $77.6 billion, is seeing a surge in companies offering extensive health screenings. These companies promise to improve your healthspan by analyzing vast amounts of data. Some, like InsideTracker, assess overall health through hundreds of data points. Others, such as function Health and Superpower Health, use AI and expert analysis. To cut through the hype, we consulted two experts to discuss the implications of these tests.
The Experts:
Keith W. Roach, MD, is an associate professor of clinical medicine at NewYork-Presbyterian.
Christopher Kelly, MD, a general cardiologist from UNC health, specializes in cardiovascular imaging and co-authored Am I Dying?!: A Complete Guide to Your Symptoms-And What to Do Next.
What is a Biomarker?
christopher Kelly, MD: “A biomarker is a biological substance that can be objectively measured and tracked to provide information about a health condition. A few common examples include LDL cholesterol, which is a biomarker of metabolic health and prostate-specific antigen, which is a marker used to screen for and monitor prostate cancer.”
“Essentially, every blood test that we do can be considered a biomarker.”
Keith W. Roach, MD: “There are a whole lot of them.Essentially, every blood test that we do can be considered a biomarker.”
Why the Sudden Interest in Extensive biomarker Testing?
Many people are now paying meaningful amounts for comprehensive biomarker testing. But why is this trend emerging now?
Dr. Roach: “I think people can sometimes be frustrated by what seems like 19th-century technology from the doctor, where we use a stethoscope and we ask a few qu
Frequently Asked Questions
- What are the benefits of biomarker testing?
