Function HealthReviews of functionhealth.com

I'm 56 year old woman in menopause that HATES DOCTORS and the current medical community mentality of "here's a pill" for every problem that walks in the door. After a 6 year absence from I used Function Health for a full blood workup and an add on allergy test. Absolutely fantastic experience! Found out doctors recommending "allergy" pills and nasal sprays were ALL WRONG. I have food sensitivities; I eliminated those foods and what do you know, I can BREATHE AGAIN! Test results were exceptionally thorough as well as clinician notes. I've adjust my lifestyle and diet accordingly and can't wait for a 6 month follow up. HIGHLY HIGHLY RECOMMEND. Your regular doctor will NEVER do this thorough bloodwork. Ever.

Hidden fees, don't believe their pricing on their website. Function Health charges $613 for their health check in New York. It's $365 plus an additional $248 billed at the lab. I didn't realize this until I got to the lab and they told me that I would have to pay the additional amount. The ridiculous thing is they can't provide any service to you at all without the additional fee. So of course I emailed them to ask for a refund and they still haven't got back to me. It's been almost one week and I am so angry and disappointed.

Function Health is misleading in many ways. For your second blood test you only get 25% of the bio markers that were in the first test. If you want trend analysis, you need to buy more. That is not clear in their advertising. Also, you never engage w Dr, including notes and summary. All of it is an AI language model, Disappointing

Good price for the tests and attractive interface. I have generally been frustrated about some of their policies like taking away the ability to have lab results uploaded to My Quest as well as Function which limits our access and what we are able to control about our data as Quest supports API functionality, though Function does not. There may be security concerns as Function claims, though with both Quest and Function being HIPAA, I don't really see it. All they can really say is having our results available in more than one place is less security, but many of us want the ability to use the Quest API to easily sync our results with other systems. Maybe that is less secure, but it is done by our own choice and hopefully we are choosing secure systems. We download our PDF's and share them wherever we want so all Function is doing is making it harder to use our data outside of their system. Almost every blood testing organization allows for API syncing, so function is an outlier on this decision though they are new and still developing. I want to like function, though I wish they would allow us to continue to get our data in My Quest while they continue to develop their product. It took me months of messaging them about this to finally get an answer that didn't feel like I was just being brushed off. I appreciate that I finally got a better answer, but wish it hadn't required so many messages to get a better answer. "Thank you for sharing your perspective so candidly. I hear your frustration, and I want to acknowledge how strongly you feel about having control over your own health data. You’re absolutely right that both Quest and Function operate under HIPAA regulations, and your feedback about data access, flexibility, and trust is valid. Our current approach isn’t intended to limit your autonomy or discourage the use of external tools, but rather reflects how our platform is structured today around data security, compliance, and consistency of results delivery. That said, we understand how this can feel restrictive, and we recognize that ease of access is an important part of the member experience. While you can download and use your results PDFs as you choose, I understand your point that this may not feel like the most seamless or empowering option. Feedback like yours is important, and we do share concerns like this internally with the teams responsible for platform decisions and future improvements. We genuinely appreciate you taking the time to explain how this impacts your trust and willingness to continue with Function. If you’re open to it, I’m happy to pass your feedback along so it’s heard by the appropriate team."

Function health was not up front about lab locations. I did not find out until after signing up that the closest lab locations was over 90 miles from my house. They would not give me a full refund even though I did not receive any services from them despite a request for refund being submitted only a couple of weeks after signing up. Horrible customer service and transparency. Try to understand lab locations before signing up so you don’t get ripped off as well.

I signed up with Function in January 2025. The product from them was pretty good. Sure, its a little pricy and the doctor notes were underwhelming. However, the app is very user friendly, and they display your data in a way that makes it easy to find, read and understand. Booking your lab visits is convenient (all through the app) and very forgiving of last minute cancellations and re bookings. I was able to get some add on testing that proved to be beneficial to my every day life and I was most appreciative of the product they provided. I recommended it for others. My favor for them ended when 2025 did. I only intended on using their service for one year (as I cannot afford to use them every year) but I looked forward to going back eventually when the time was right for me. In mid January I realized I was charged $365 by Function on Dec 31st 2025 and quickly found out it was a "recurring charge". Now that may have been something I skimmed over when I was signing up but I quickly used their AI chat box to request a refund and it easily obliged and told me to wait a few business days for the refund. A few days come and go and I get a refund for $233.35, a partial refund. I message Mr. Ai chat bot that I was expecting a full refund. Since idk.. I'm not using their service this year but unfortunately Mr. Ai informed me that I needed to cancel my membership within 48 hours of being billed. So, I email a human about my problem, and the man was nice, professional and responded 1-2 times a day. That is where I was informed that I was a "member" and this is an annual charge...He claimed function sent an email 2 weeks prior, alerting me of the upcoming charge. I have checked my email several times and I cannot find that email. I was asking questions like "when did I become a member?" "How do I cancel my membership? Did I sign any contract? Will I currently be billed next year?" Why are you keeping $130?". I couldn't find any of this information on their app because it is not displayed. Disappointing to find this all out in the 11th hour to say the least. I was told their 48-hour cancellation policy is black and white so no refund for me, they just get to keep the remaining $130 for funzies because I caught the charge to my credit card 3 weeks later instead of two. My credit card company is handling the issue now, so the outcome remains to be seen. Overall, I find it really rich that a company that designed a great user-friendly convenient app was unable to clearly display any profile settings, membership status and financial records. Poor communication is one thing but to then not honor my request for a refund is disappointing when I didn't even purchase/receive anything from them I'm sure they make a lot of money off unassuming customers like myself. Good product, bad communication and bad customer service. Update: Function Health did end up giving me a full refund which gives them an extra star. Wish it happened earlier but I appreciate several members of their team reaching out and making the situation right. Thank you.

BEST ACTION I TOOK ALL YEAR! With the results obtasined I was able to share tghem with my private doctor and settle issues that were haunting me. its a great toolk to get ALL the annual info and thern have Function Health anylize it . Beter than any "second opinion"

I was a curious about my biomarkers as I age. More importantly, I was curious about what to do to correct any levels that suggested a problem. Function Health provides two blood draws a year. The first is about 10 vials of blood or so and they provide all sorts of instructions about how to prepare, what to stop, what to drink in advance, etc. The results are returned in an easy to read, understandable format a few weeks later. Three to four months after the initial draw, they remind you to schedule a second blood draws, about half as many vials and they follow-up tests of key markers. Their website and materials do a great job of laying out exactly what they are going to do, and then they execute it and send a report, which I gave to my physician. The only thing I didn’t like was when scheduling the second visit the system makes you select or decline about 40 additional tests before you can schedule. That was annoying.
