Anyone know the basis for this cancer claim? Apparently I'm in the 1%

**"**No cancer signal was found at this time. This does not rule out the presence of cancer or predict whether you will develop cancer in the future. Not all cancers can be detected in the blood or by the GRAIL Cancer Test. With that said, in a clinical study, less than 1% of individuals with a “cancer signal not detected” result had cancer."

I got this result in March. April mammmogram led to biopsy which confirmed early stage breast cancer. To be fair, Function say not to skip mammograms, and no woman should. But if your concern is breast cancer you might be better served by paying for breast MRI than a blood test.

Found out I had an omega-3 level of 0.3%, after working on it, a lot of chronic health issued are improving.

I have too many health issues to count, none of my doctors (or Claude) ever thought to test me for omega-3. Now I’ve been supplementing for 2 weeks and I can already feel some improvements.

I never would have made this discovery without Function Health.

For reference, below 4% is seen as high risk.

Is customer service still bad?

Product seems great and there is a sale, but the reviews are so bad on here when it comes to customer service, including the company making it very hard to cancel membership… anyone have any recent experiences?

Guidance Please

Looking for advice on the next best steps regarding function lab results. Some background info: female, 42yo, 160lbs, 5’ 6,” and mom of 3 young kids. I workout 5x a week doing crossfit. My cardio needs work. I have worked out consistently for the last 17 years. My diet could stand to be cleaned up. I try to watch my calories for weight management.

Family history:
My mother had open heart surgery and has also had a few small strokes. On the maternal side, more heart attacks, stints, pacemakers and congestive heart failure in different family members (but very different lifestyle, than myself). I’m thinking I need a statin. But I’m sure this sub can help me hash out what type and the best course of action, please. Some of my cardiac numbers are alarming. Appreciate all the tips and knowledge.

Missing results on first test???

I had labs drawn 3 weeks ago. Only 44 results received. I have already received the clinician summary and it says all results are complete. When I look at the list of tests included I am missing several. Has this happened to anyone else?

Do I get the add on thyroid test?

I have a $50 credit that expires today, so I want to take advantage, should it be helpful.

My TSH came back high. My free T4 and free T3 range“ though. I had labs done three years ago and it’s the same result… TSH is high, free T4 and free T3 were “in range“.

will the extended thyroid lab help me find anything additional, or is it not really worth getting?

My follow up test is being done July 2nd (this week) and my membership ends July 9th (next week). Will I still get my results?

I know there’s a delay in interpretation and getting the clinician notes. Does anyone know how this would be handled?

I'm having my annual physical tomorrow but I'm thinking of joining Function in addition to that?

I heard about Function on the Huberman podcast. Seems like a pretty cool idea to do in additional to my annual physicals. Y'all like it or would you recommend something different? Thank you!!!

Charged $149 for blood draw

Really surprised by this and have reached out to the billing department.

When I signed up it said concierge blood draw is no added cost in my zip.

Is this normal? Did I miss some fine print?

Mid-Year Bloodwork: Can someone help me make sense of my iron panel?

Can someone help me make sense of my iron panel?

I just got bloodwork done and I’m confused because my actual iron looks normal, but my iron saturation is flagged high and my ferritin dropped.

Current results:

  • Iron total: 128 mcg/dL, normal range 40-190
  • TIBC / iron binding capacity: 257, normal range 250-450
  • Iron saturation: 50%, flagged high, range 16-45
  • Ferritin: 54 ng/mL, normal range 16-154

For comparison, in December my results were:

  • Iron total: 117
  • TIBC: 256
  • Iron saturation: 46%, also flagged high
  • Ferritin: 86

So my saturation has been slightly high twice now, but ferritin went down from 86 to 54 and is still technically normal. I’m not anemic — hemoglobin is 13.4 and hematocrit is 40.8. Liver enzymes were normal too.

I’m trying to understand what this pattern usually means. Is this just because my TIBC is on the low end, making the saturation percentage look higher? I am not taking any supplements with iron and did not have an iron rich meal before my bloodwork. I’m taking/looking at prenatals and TTC soon, so I’m wondering if I should avoid extra iron or ask for repeat testing.

Not asking for a diagnosis — just curious if anyone has had normal iron + normal ferritin but high iron saturation, and what your doctor ended up saying.

All blood tests come out clear. Should I try ATP/mitochondrial tests ??

I’ve had mild ME/CFS symptoms for over a year, but things became severe over the last 6 months following surgery complications. After a massive crash last month, I went from being bedridden to currently housebound. All these months I have been dealing with my surgery complications which have exaggerated my chronic fatigue, meaning I haven't stopped doing examinations after examinations.

Anyway, my routine bloodwork keeps coming out very good. Autoimmune markers (ANA, etc.) are clear, thyroid is clear, kidneys are clear, liver enzymes are clear, insulin/glucose are clear, basic hormones are clear, inflammatory markers are clear, cardiovascular are clear. I do need to improve my ferritin a bit though. I also have a brain MRI scan planned just to rule out other things.

Since all the major systems SEEM to be fine, I researched a bit and found that there might exist a link with cellular energy disfunction? Like the issue is actually happening at a cellular level with ATP/mitochondrial energy production. Tbh, fatigue "on a cellular level" is precisely how I personally experience my kind of fatigue, so it sounds plausible.

There is a clinic where I live that offers an Organic Acids Analysis (OAT), a Plasma Fatty Acids Analysis and stuff like that. I am attaching the charts from their tests here. These panels map out the Krebs Cycle (Energy Production), cellular carbohydrates/lipids/proteins metabolism, oxidative stress markers, neurotransmitter metabolites, and Omega-3/Omega-6 pathways.

Regardless of the money these tests cost, I would like to know whether there is any scientific reason for me to delve into this approach. Since I have not found answers with the typical tests, why not take a more exploratory view? There are also a few papers discussing this view.

I am just wondering and I am also hoping. Has anyone else here done a full OAT for their ME/CFS? Did looking at your Krebs cycle or fatty acid pathways or metabolites actually help you find targeted supplements? And, therefore, help with treatment??

Please help with anything you know or personal experiences!!

P.S.: I am a bit new to this new shitty life and new to this sub reddit so if this topic has been brought up already, please send me the original link and I will read it through! Thanks!

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?

Additional fees for labs in NY?

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.

Thyroglobulin antibodies value?

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.

New research out of Harvard links prenatal PFAS exposure to PMOS (formerly PCOS)

“Scientists are increasingly concerned that certain everyday chemicals may be interfering with our hormones – and possibly for generations to come. According to a recent publication in Environmental Research, mothers who had higher concentrations of certain “forever chemicals” in their blood were more likely to have daughters that developed polycystic ovary syndrome (PCOS) [now PMOS*] and moderate-to-severe acne by their later teenage years.

Dr. Zifan Wang, Research Associate in the Mahalingaiah Lab (Harvard T.H. Chan School of Public Health) and others followed 322 mother‑daughter pairs enrolled in Project Viva, a long-term Boston-area study that included mothers who were pregnant between 1999 and 2002, to reach these conclusions.

Using blood samples and survey data, they found that mothers who had higher levels of a chemical called EtFOSAA in their blood were 2.7x more likely to have a teenage daughter with PCOS. Mothers with higher levels of PFNA were 2.3x more likely to have teen daughters with moderate‑to‑severe acne.

Of note, when the researchers looked mothers who had been exposed to all six PFAS together as a mixture, they didn’t see a clear overall link with PCOS or related traits.

EtFOSAA and PFNA are both chemicals that belong to a larger group called PFAS (per- and polyfluoroalkyl substances). Commonly, these chemicals are used in products like nonstick cookware, stain‑resistant fabrics, and food packaging. PFAS build up in the environment and the body over time and don’t break down easily, raising concern about long‑term health effects.

This study suggests that exposure to certain PFAS during pregnancy may play a role in daughters’ reproductive health years later, the scientists explained, but it doesn’t prove cause and effect, and the sample size was relatively small.

More research with larger groups and longer follow-up is needed, they said – especially because most mothers in the study were non-Hispanic White and college-educated, which limits how broadly the findings can be generalized. Still, their findings add to the growing concern about PFAS in our environment, and they support efforts to reduce exposure.”
