Why every wellness company wants your blood sample

Blood panel diagnostics, which were traditionally only ordered by one’s physician, are becoming big business in the wellness world. 

Last week, Function Health announced the acquisition of Getlabs, a mobile lab testing network that sends a certified phlebotomist to one’s home or office to collect lab samples, including blood, urine, stool or saliva, before delivering them to a partner lab for processing. 

The telehealth platform launched in 2022 with direct-to-consumer medical testing, including labs for nutritional deficiencies, hormone irregularities and other biomarkers it says are often missed in traditional medical visits. Function’s acquisition of Getlabs seeks to make lab collection easier and faster for its 500,000 members. 

“Ultimately, you can’t really define your health without knowing your personal health data,” Mark Hyman, MD, co-founder and chief medical officer of Function, told Glossy in February. “And that’s really where Function comes in. It allows you to understand what’s going on with your biology in real time, to put your biology online, [and] to have it really give you insights about what’s happening.”

To do so, Function Health has an in-person partnership with Quest Diagnostics, the labs business with more than 6,000 locations across the country. This partnership will continue, but now Function users will have at-home and in-person options: Those who select Getlabs will have their samples delivered to Quest for processing. 

Function Health members pay $365 per year with one round of included blood test labs. Extra tests can be added à la carte. 

Getlabs launched in 2021 with a $3 million seed round from Pivot North Capital, then raised $20 million in Series A funding in 2022. It was led by Emerson Collective and the Minderoo Foundation. Getlabs was helmed by founder Kyle Michelson, who worked as CEO until June 2025 when Claire Hough, former CTO at Carbon Health, took over as CEO. 

The global blood panel diagnostics market was valued at $94 billion in 2024 and could exceed $160 billion by 2030, according to market research firm Grand View Research. The firm has charted a compound annual growth rate of 8.83% for the industry, which is led by North America with 44% of the market. 

According to the firm, the most common reasons to seek a blood panel include testing an individual’s blood sugar, including A1C and glucose testing, followed by cholesterol testing, which is categorized as LDL or lipid testing, followed by Covid-19 tests. Kidney, thyroid, and prostate testing populated the next spots. However, only one nutrient test ranked in the top 10: vitamin D testing. 

This aligns with a 2010 study at Oregon State University that found 95% of adults are deficient in Vitamin D, which has been a primary focus for new supplement brand launches. 

However, as the supplement space has ballooned in size, many health experts warn against “supplement stacking” without first understanding one’s nutrient deficiencies, which is done through blood panels. 

“People are walking around feeling like crap, [and] they just don’t know why,” Hyman told Glossy. “[Then they see their blood test results and realize], ‘Gee, wow, my vitamin D is like [a level] 12. No wonder I’m getting sick all the time, I’m tired, my muscles hurt, and I feel depressed — I thought that was normal.’” 

The blood panel market is currently populated by leaders like Quest Diagnostics, as well as at-home leaders like Abbott and Roche Diagnostics, which offer cutting-edge solutions for at-home testing and glucose monitoring. Grand View Research also identified two emerging players: Guardant Health, which reported $281 million in revenue in Q4 2025, and Bio-Rad Laboratories, which generated $693 million during the same quarter. Both are headquartered in California and offer various at-home lab tests. 

Meanwhile, blood panel diagnostics have become a hallmark of longevity clinics like Love Life, launched by a former Whole Foods founder in 2024, and Miora, the new longevity clinic from luxury gym Life Time Fitness. Membership at Love Life starts at $650 per month, while Miora offers a diagnostics package, which includes a consultation, blood work and a wellness protocol, for $299.

Nearly every heavy hitter in the health data tracking market has added blood panels to their list of offerings. For example, users of the Whoop wrist tracker or Oura ring can purchase blood tests through their app to check for a bespoke combination of biomarkers. Launched in September and October, respectively, both tracker brands partner with Quest Diagnostics to facilitate the tests. Oura charges $99 per test, while Whoop operates an annual membership that starts at $199 and includes one test. 

There are also health platforms based primarily around lab test analysis, like Superpower, which facilitates payment, scheduling and analysis of tests done at Quest Diagnostics locations. The company raised $50 million in Series A funding led by Forerunner Ventures last year. Then there is Levels Health, co-founded by Casey Means, MD — President Donald Trump’s current nominee for U.S. Attorney General — in 2019. The health platform utilizes continuous glucose monitoring devices to track blood sugar and other biomarkers. 

But Function Health isn’t the only health data company eyeing vertical integration. 

In early 2025, Hims & Hers announced plans to introduce at-home lab testing through its acquisition of New Jersey-based Trybe Labs, maker of an FDA-approved, minimally invasive at-home blood-collection device that allows users to collect their own blood at home and mail it to the lab. The company also announced plans to acquire YourBio, a Boston-based maker of its patented TAP device, which uses a proprietary Halo microneedle system to collect blood at home.
