Function Health joins Google Health, and the hype check still applies.

What Google and Function actually announced

On October 12, 2026, Function Health and Google Health said they are linking up. Later this fall, US users will be able to import their Function lab results straight into the Google Health app, where they will sit next to data from Fitbit Air, Fitbit Edge and Pixel Watch 5: resting heart rate, sleep, heart rate variability and cardio load. Google's AI tool, Health Coach, will use the combined picture to offer what the companies call tailored wellness guidance.

Function co-founder and CEO Jonathan Swerdlin framed it as a shift from fragmented data to something more useful. "Everyone deserves to own their health," he said in the companies' announcement. The same day, Google also unveiled its next Fitbit tracker, the Fitbit Edge, and a separate multi-year partnership with Flo Health, the women's cycle tracking app, with syncing due to start early next year. None of this is a single product launch. It is Google stacking three health data deals into one announcement, which tells you more about Google's ambitions than about any single feature.

The money behind Function Health

Function is not a scrappy newcomer. The Austin company, co-founded by Swerdlin and physician Mark Hyman, sells memberships that run 160-plus lab tests for $365 a year, with optional full body MRI and CT scans added through its 2025 acquisition of imaging startup Ezra. It has also bought mobile blood draw network Getlabs and supplement testing outfit SuppCo.

The valuation explains why Google wanted in. A $298 million round in late 2025 priced Function at $2.5 billion. This past July, General Catalyst added another $450 million in growth financing, pushing total funding past $800 million. That is a lot of capital betting that healthy people will keep paying to retest their blood twice a year. A Google Health plug in gives Function a far bigger audience to sell that subscription to, since Fitbit and Pixel Watch alone cover tens of millions of devices.

What the data integration can and cannot do

Pairing a lab panel with a wearable is a genuinely useful idea in principle. Markers like ApoB, Lipoprotein(a), hs-CRP and fasting insulin are real, clinically used numbers. Tracking how they move alongside sleep and training data, instead of as a one off PDF, is a fair way to notice trends. That part of the pitch holds up.

What does not hold up yet is the bigger claim, that this combination will help people recognize changes in their health earlier. Neither company has published outcome data showing that. Google's own disclosures, printed in the same announcement, say Health Coach's answers may be inaccurate or incomplete, and that Google Health is not intended to diagnose, treat, cure or monitor any disease. That is a standard legal hedge, but it also happens to be the honest answer: an AI summarizing your blood work and your sleep score is not the same as a clinician deciding whether a result actually matters.

The overtesting problem nobody is advertising

We have looked at direct to consumer blood panels before, and the conclusion holds here too: the individual tests are legitimate, but running a wide panel on a healthy person with no symptoms raises the odds of a borderline result that leads nowhere useful except another appointment, another test and, often, more anxiety. Function's own marketing leans hard on biannual retesting, which is good for a subscription business and not obviously good for a patient who was never at elevated risk in the first place.

Making the results easier to see on your phone does not resolve that tension. If anything, folding lab values into a chat style AI coach makes it easier to act on a number before anyone has asked whether it was worth testing in the first place. Mainstream screening guidelines exist precisely because testing everyone for everything, on a schedule set by a subscription business rather than a clinician, tends to generate more follow up appointments than it prevents. None of that makes the individual lab values fake. It just means the question to ask is not "what did my panel find" but "would I have ordered this test myself, and would I act differently depending on the result."

Our take

The Function and Google tie up is a smart business move dressed up as a health breakthrough. Centralizing your own data is genuinely convenient, and nobody should begrudge that. But the partnership answers a design problem, not a medical one. For Google, it is also a distribution play: Function gets access to the installed base of Fitbit and Pixel Watch owners, and Google gets a reason for people to open its health app more often. Neither of those is a bad business goal, but neither one is evidence that the product makes anyone healthier. Before renewing a $365 membership or letting an AI coach weigh in on your bloodwork, decide what you would actually do with an abnormal result, and plan to discuss it with a doctor, not a chatbot.
