The report after labs is lacking. It almmost repeats what I already know from the test. I have also had issue with renewing membership

Hi Nancy, we are sorry to hear that you are having issues with your membership renewal, our team has reached out via email to assist you further.
For context, your Mid Year set of tests does retest 60+ of the 100+ biomarkers initially included in your Yearly test. Our team of clinicians recommend testing these 60+ biomarkers every 6 months as they are most influenced by change during that timeframe.

Good for low cost labs
I think the service is good for low cost labs. But beyond that, there's little advantage. The reports are very generic and hardly follow functional medicine principles likely because of liability. There was no discussion of positive or negative trends in my report. There needs to be much more history gathering. Especially, recent changes that could have affected the lab values. As an example, if I'm on TRT then labs need to be examined in that context. As far as recommendations, it seems to be pill for condition supplements which does not follow functional medicine. This is also obvious in the reports as each system is evaluated without the big picture. So, I will continue the service because I do my own evaluation. But there's so much to improve.

Function Health- the good and bad
Function Health is an incredible transformation to how we think about our health and wellness. It provides a comprehensive health report and tests over 100+ biomarkers.
My only criticism is the doctor's follow up report. It's all AI generated...doesn't feel there's any personalization or tailored suggestions.
Response from Function HealthOct 9, 2025
Thanks for your thoughtful feedback and for recognizing the transformation Function Health is bringing to proactive wellness.
We hear your desire for more personalization. While AI helps us summarize complex data, every report is reviewed by a licensed clinician and we’re actively working to make them feel more tailored to each member’s goals and history.

To Much Waiting for amount of money it is
Easy to read. WAY to long to get results. You can go direct and get results from almost all of these test by Ultralab or other places in a matter of days. Its unclear to me how and why it takes weeks or months to get some results. Having worked in the lab samples sitting around for so long are suspect to storage issues and chain of custody and degredation

Idiotic customer service
The platform is great and the idea behind the business is great. But customer service is almost unbearable! I need to repeat 4 times my simple request of getting a copy of Anytime Tests which I ordered to retest the out-of-range markers from my annual test! So far I have not got a copy of the Anytime Tests after numerous tries. The customer service team do not read well and do not think at all! It is an absolute shame that such low quality service is being rendered for a high-tech leader in the healthcare industry! There should be a phone number for us to call and a way for us to escalate our complaints instead of dealing with idiotic reps via texting for weeks! Will not recommend the service if the customer service does not employ people who can read and think!

Good Information | Inconsistent Customer Service
Function Health is heavily advertised on social media. I've seen many ads on Facebook. Their basic service is $500 for a comprehensive set of tests which measure a variety of different "biomarkers." This is how they describe it: "100+ lab tests and insights from top doctors."
I'll start with the positive first. The results are posted online for you in an easy to read format that includes a comprehensive report about the state of your health. They even provide you with suggestions for next steps to take to improve your health. I'm not sure where those "insights from top doctors" come in! Perhaps they're incorporated into the report. I'm quite sure that there are no doctors personally looking at your results!
And now the reason why I gave Function Health just 3 stars. Their customer service is somewhere between mediocre and abysmal. First of all, they don't offer any phone support. $500 is a lot of money to spend not to be able to speak to anyone on the phone! They have text support (through a web form) but, in my experience, the quality of that support varies greatly!
I've spent the last few days chatting with several people--but not in real time--about what I thought were some pretty basic questions. When they're not flat out ignoring my questions, they
often can't seem to grok what I'm asking. The questions I've posed are very basic! Out of frustration I turned to ChatGPT and got a perfectly lucid, easy-to-follow answer to my query. When I posted the results, in a follow-up question, to confirm that they were accurate, they completely ignored the question!
When I say the chats are not in real time, I mean that I may have to wait 12 hours or more for a reply. And, as I pointed out, that reply, especially as of late, often doesn't even address my questions! I've asked repeatedly if I could please talk to someone; but they just keep reiterating that they only do support through chat and text.
As for the actual testing, it mostly happens through Quest Diagnostics. Apparently there are many locations around the country but, as the popularity of Function Health surges, they are often staffed by over burdened phlebotomists. In other words, it's like a blood drawing assembly line. That being said, my experience was okay since I was aware of this going into it and tried to bring some lightness to the interaction (which helped).
So, in summary, I'd give Function Health an A for the end result (the comprehensive report), a C+ for the actual testing (mostly blood drawing), and a D for customer service.
UPDATE: After repeated attempts to get my questions answered, Ashlyn reached out to me. She was very helpful and apologetic. She provided me a number where I could text the company with future queries and also mentioned that she'd passed on my feedback about the poor customer service I experienced. Hopefully, this will help them to improve their communication and provide a more timely method of getting help!

Full Disclosure (about the link above): I get a kickback if you decide to sign up for it. Obviously, an honest review is more important to me than hyping the company for a fast buck! But, as you can tell from reading my review, I do value the end result, even if their customer service could be improved. There are alternatives to Function Health with better customer service but the ones that I found were over $1000 dollars, some of them into the thousands of dollars.

Disappointed that Physican "Integration" is Just (Many) PDFs
I am disappointed with how lab results and related information are shared and organized. While I value the insights the functionhealth platform provides, it has significant obstacles that limit its effectiveness.
1. Difficulty Sharing Results with Physicians
There is no easy way for me to share my lab results, with your accompanying notes, with my various physicians other than providing them with a PDF.
You do not provide my physicians access to the results via platforms like MyChart or Quest, which complicates the sharing process.
Without an accessible, organized ONLINE system for my doctors to view and interact with my result, I fear I will not receive the level of guidance and assistance I need. Without online access my doctors cannot see trends.
2. Organization of Lab Results
The results provided are not organized in a clear or intuitive manner. I find it difficult to interpret the layout, and I believe my physicians would feel the same. I had one blood draw but have three pdfs!
A more user-friendly format or a summary dashboard tailored for healthcare professionals could help bridge this gap.
3. Delays in Test Availability
I am disappointed that the OmegaCheck test has been delayed for six months. I was hoping to review this data sooner as part of my current health assessment.
4. Lack of Physician Integration
When your report lists recommendations, such as six potential supplements to reduce fibrinogen, I am advised to consult my healthcare provider. However, without an accessible platform for them to view my data in an interactive and organized way, I am left to manage these decisions on my own. Do I get all six??
This undermines the purpose of the service, which I assume is to facilitate informed, collaborative care.
Suggestions for Improvement
Physician Access: Create an option for physicians to access patient results online, similar to (ideally on) platforms like Quest or MyChart. This could include secure logins for ongoing access.
Improved Organization: Redesign the presentation of lab results to be more intuitive and actionable, perhaps with physician-friendly summaries or decision-support tools.
Faster Test Availability: Work on reducing delays for critical tests like OmegaCheck to ensure timely insights.
Patient Support: Offer resources or consultations for patients who cannot rely on their physicians to act on the data provided.
Feedback: There is little opportunity to provide feedback other than by chat or a closed-type questionnaire. That's why I am this site -- because I can't get through to functionhealth.
Closing Thoughts
While functionhealth offers valuable information, the current limitations make it challenging to fully integrate these insights into my healthcare. I believe addressing the above issues would significantly enhance the platform’s usability.
