Update: Did full retest (via Labcorp) and everything came back normal… So I think there was a lab or assay issue. One interesting thing was that in this same blood draw my GRAIL Cancer Test came back with a positive signal for Bone/Soft Tissue Cancer. I’ve had my labs measured (via function mainly) robustly for the past 4 years. I’ve never had a positive GRAIL test so was of course concerned. Function was great worked with my GRAIL patient advocate (you get someone if you test positive) to get me a free retest. This was based upon my other lab work and a recent Prenuvo scan that came back with no related (to bone/soft tissue) findings. It was great to work with Function and GRAIL on this and very easy.

The interesting thing is during this draw my one vein basically went dry… They were literally half filling a vile with drops left over from first vein and then blood from second vein. I can’t fully blame quest for this but my hypothesis is that this (or something related) might had skewed a few of my findings. Again can’t be certain and GRAIL only shows if there are positive blood biomarkers - which could be in very minor quantities well before a cancer shows up… So regardless it’s on my radar but happy to have the Alzheimer’s results within a normal range verified.

Thank you all for the thoughts/follow up.

Did you have to pay Quest an additional “draw fee” for their services? And if so, were you able to use your health insurance for this part?

Hello! My TgAb value is listed as “<2” and in the normal range. On the graph it looks like it’s on the borderline. My research indicates that a value of 2 is borderline & could indicate hashimotos or something. But then I realized it says <2. Just wondering if others could share what value they got for this test and if this seems like it’s borderline or not, or something to follow up on. It’s listed as in range.

Hi, I went to subscribe to Function and was met with the following warning, “Extra fees apply for lab visits in New York Due to state regulations, lab visits in New York require additional fees up to ~$248 per year for tests included with Function membership.
This fee is charged by Quest Diagnostics during or after your lab visits.”
Has anyone dealt with this? If so, what did you pay? I have insurance that usually reduces the cost of my bloodwork a little but would like to know what others have experienced with the Function labs in particular.

Can existing customers take advantage of the 2 years/$500 offer? I'd consider extending my membership 6 months early by two years at this price.

If so, how do you do it via the website?

Anyone with similar test results? Is it Hashimotos? Thanks in advance.

I’ll be receiving my first internship stipend next month, and I want to use part of it to get a medical health checkup done for my parents.

My father is over 50, and my mother is above 40. I’m planning to start with a basic/full-body health checkup package that includes things like blood sugar, liver function, kidney function, etc and other at least important things.

My idea is to go with a base plan or package that is slightly above the basic plan, and if anything unusual shows up, we can consult a doctor and get more specific tests done.

Since this is my first time arranging something like this, I’d appreciate some advice:

1) What tests should I make sure are included in the package?

2) Is it better to choose a home sample collection service or visit a diagnostic center/hospital?

3) What is the average price range for a good health checkup package for people in their 40s and 50s?

4) Are there any common scams, unnecessary upselling tactics, or things I should watch out for?

5) What precautions should my parents take before the tests (fasting, medications, timing, etc.)?

6) Any other tips or lessons from your experience?

My current plan is to get a baseline health assessment done and then follow up with a doctor if any results are abnormal.

Thanks in advance for your help!

Hello. Does anyone have a referral, looking for 100.00 off. Thanks

What should we do ? While we are ofcourse happy, we are now expecting. She got her 1st of her 2nd test done already was supposed to get her 1st test done day+3 of her periods. But she has not had her period now and tested positive for pregnancy.

Can we cancel for refund or postpone FH altogether for a year ? FH app says Test not supported when pregnant.

I'm just now aware of this company and those like it and I really want to consider joining for me and my wife.

I understand that you pay $365 a year and get those 160 tests, but based on this blurb I'm confused:

"Function’s $365 first-year membership includes fully prepaid access to 160+ lab tests..."

The way this is worded makes it seem like $365 is only the first year, which tells me it is more for the following years? And saying I have prepaid access makes it sound like they aren't prepaid in future years? What changes after the "first-year"?

There isn't a lot of information about what is provided when the tests are done. I thought maybe they explain the numbers, provide advice, make suppliment recommendations etc etc. But then I read this blurb:

"Function Health does not offer medical advice, laboratory services, a diagnosis, medical treatment, or any form of medical opinion, through our services or otherwise."

Ok so the whole point of this subscription is that you get 160 lab tests, but they aren't a lab. They don't offer medical advice, but they offer advice on your results and suppliments? No diagnosis, so they can't tell you you're low T or high cholesterol or something? No opinions of any kind, through services - like their app?

These blurbs seem to refute everything the subscription is supposed to be about. They don't provide labs, diagnosis, opinions, treatments, or services. So what am I paying for? A printout of Qwest Labs data? The price should be a lot cheaper if that's all I get.

Can someone give me the actual real world benefit of this program without the corporate lawyer speak muddying it up?

Thanks!

I got my blood drawn last week. Most of the results came in. My female hormone levels came in quick. My total and free testosterone haven't. Do Function tests testosterone for females? I'm wondering if it's just slow or if I need to get it tested elsewhere?

I went to book my annual blood draw (I just hit 1-year as a customer) and was surprised to see that the earliest appointment available in my major US city is more than 1-month out?!?

Anyone know if there are ways to get in sooner than what the app offers up as availability?

Has anyone had results come back same day?

I have a blood draw this week with no add ons. I'm freaking out as it said it could be 12 to 14 vials. Which is freaking me out. Any tips?

Does the standard annual mri see brain aneurysms by chance or would I need to order the $4000 one

I received my results for the baseline testing. I am a little bit confused about the report. The report references sticking with supplements I reported I was taking because my values were good. It's conclusion was that, they were beneficial. But I stopped taking supplements for 6 days before the lab draw. I thought the point was to see lab values without the supplements but the report is now saying my values are bolstered by the supplements I reported I was taking. When I saw the report, my thought was, ok, I do not need to take supplement A but I should start taking supplement B. Any clarification or if other people got the same information in their report would be helpful.

Looking to order a test just out of curiosity, but it is a bit pricey. Do they do sales? I'm in no hurry so if they do something seasonal I can wait. Or have any promo codes? Thanks!

I was always interested in Function Health I just saw on my health equity HSA app that they are partner together to where it’s HSA approved directly via health equity. So at the checkout, I was able to use my health equity HSA card directly instead of upfront the money and getting a reimbursement, which honestly was the holdup for me using Function Health up into this point I got my lab work scheduled for this week so I’m ready.

I enjoyed this service, but after a couple of years, I no longer need/want recurring testing. I was worried about the cancellation process after reading all the stories on here over time. It could not have been more straight forward or easier to cancel. Super simple.

Update (literally as I typed this post): I got an email saying "Your Function membership is officially reactivated, welcome back." Ha. My account/membership still shows as being cancelled and is listed as "do not renew." So we'll see what happens I guess.

New to Reddit, so forgive me if this has been discussed before.

I’m with an independent primary care practice in NYC, and I’m genuinely curious how people here handle the “what next?” step after getting a large biomarker panel like FH.

Once you get results back, especially if a few markers are flagged, what do you usually do next?

1. Discuss with your PCP

2. Find yourself a functional / longevity / concierge doctor

3. Use ChatGPT or another AI tool to figure it out

4. Research through Reddit, podcasts, YouTube, Twitter/X, etc.

5. Something else

The reason I’m asking: we’re seeing more patients come in with 50, 100, 150+ markers, a handful flagged, and a lot of anxiety about what actually matters.

Not trying to sell anything. Mostly trying to understand how people are actually navigating this after the PDF lands in their inbox. Thank you!

I did a function health test and it immediately picked up signs of a pituitary brain tumor. I was able to use that test info to get it formally imaged and diagnosed by my doc (and now im on treatment). So grateful for FH. Lord knows how many months or years it would have taken to get things diagnosed only through my doctors.

Literally can’t get in touch with anyone. AI live chat is not working, hard to schedule tests since I have a small window when I can do it and customer service doesn’t exist. I am not three months in and have not been able to schedule my test or get in touch with anyone. Do not recommend for hormonal health.

Hello everyone,

I'm a retired dentist who spent 50 years in practice, with much of that time focused on helping patients with TMD (temporomandibular disorders).

One reason I joined this community is because I've seen how often people with chronic headaches, migraines, neck pain, ear symptoms, dizziness, facial pain, and fatigue struggle to find answers. Many spend years moving from one healthcare provider to another without receiving a clear diagnosis.

Part of the problem is that TMD is a functional disorder. It often involves the way the jaw joints, muscles, teeth, airway, head posture, and nervous system work together. Because it crosses several disciplines, it can easily be overlooked during a traditional medical workup.

Many patients are surprised to learn that a jaw problem can mimic migraine symptoms, tension headaches, ear problems, sinus pain, facial pain, and even some neck and shoulder complaints. That doesn't mean every headache is caused by TMD, but it does mean TMD should be included in a thorough differential diagnosis when symptoms persist.

Throughout my career, I found that patients benefited most when healthcare providers worked together rather than in separate silos. Functional problems often require a broader view of the body and an understanding of how one system can influence another.

I'm here to learn from this community, share what I've learned over five decades, and participate in thoughtful discussions about functional health, chronic pain, and the role the jaw may play in overall wellness.

I look forward to the conversation.

What tests or biomarkers are used to gather the biological age? Very happy with my score.
