r/Function_Health

The overall idea for this company is great, especially when you lack quality doctors that will deep dive into areas of concern that you have over your health. However, I went into this optimistic and ready to learn about myself. I left this company feeling like it was a money grab.

I signed up, paid my $365 and went in for the first round of testing. I will say; the amount of blood that was taken in a single visit is something that I do NOT recommend. I ended up passing out and collapsing on my way out of the door. I am a routine-blood-tester and this has never happened to me before. Regardless, I appreciated the wide range of biomarkers on my health. The clinician notes I appreciated, but the AI felt icky and I didn't care for it.

And here we are today; time for the Mid-Year testing. Well- I found out I was pregnant!
Function clearly advertises that they do not provide testing for pregnant users. I reached out explaining the situation and hoping for a partial refund since I was ineligible for the testing that I pre-paid for.....they gave me $32 back.

I explained to customer support that my first testing covered 123 biomarkers. The second batch was supposed to be "60+ biomarkers" which is about 33% of the testing of the entire membership....and a mere $32 doesn't even cover 10% of this (expensive!!) program.

No matter how much I explained, reasoned, or simply asked for a more reasonable refund, they did not care. They left the chat with the good ole "We appreciate your understanding."
And side note...if I tried to get those 60+ biomarkers of testing done myself it definitely would've cost me more than $32 dollars, come on. The refund was so disappointing.

Gotta be honest- it felt like a money grab. I miss quality customer service and genuine companies that just want to help the person, not simply overcharge them and lazily use AI to provide health advice.

27F, ordered a Fit test online, quite nervous actually has anyone done one before?

I have drastically reduced saturated fat and added fiber since I found out about my LP(a) in March’26.

March’26 vs Aug’26

LDL-C: went from 112 to 97

Triglycerides: 59 to 44

HDL: 60 to 53

ApoB: 88 to 86

TC: 186 to 163

LP(a): 191 (tested only in March)

HbA1c: flat at 5.2

hs-CRP: from 0.3 to <0.2

I am confused as to why ApoB barely moved even though LDL-C and Triglycerides reduced and my diet is pretty clean (so hopefully not fueling small particle count while reducing total cholesterol volume). I understand that a portion of ApoB is related to LP(a) that is fixed and will not reduce from diet changes. I am asking why the rest of the ApoB did not reduce as total cholesterol reduced by 12%.

Anyone dealt with something similar? Especially if diet didn’t move ApoB much.

I am finally considering statin or ezetimibe to get ApoB to be less than 60. I don’t think I can do any more diet related intervention. Based on limited reduction from diet on ApoB, is one better than the other? I am predisposed to type 2 diabetes based on family history.

And the labwork at my doctors in April showded 99 Lpa. I've gained maybe 5 pounds, mostly muscle from eating normal maitnenace calories

Will someone please help with which went into the app to add additional test, it kept asking me to add on a test that have already been included in the annual bloodwork. I’m very confused by this. Are there tests that people feel are necessary to order additionally?

Just curious lol I’m sure it’s normal for not every test result to be perfect

In 2023, I started testing with Function labs, and my PSA levels came back abnormally high for my age. I brought this to my doctor's attention, but he dismissed it and told me not to worry. At my next annual test, my PSA levels were slightly higher, but my doctor brushed it off again. By the third year, my PSA level had risen above 4.2, and I insisted on seeing a urologist. After a biopsy and MRI, they diagnosed me with Gleason 4+3 stage 2 prostate cancer.

I underwent surgery to remove my prostate in June. This service truly saved my life. The doctors were skeptical throughout, saying, "You're too young to have cancer." However, with the data from the labs, I was able to advocate for myself. I'm now cancer-free, and because I'm so young, I've experienced none of the typical side effects from the radical prostetectomy. Things feel almost back to normal. I'm incredibly grateful I started using Function back in 2023—if I hadn't discovered it, I might not have lived to see 40.

I recommend Function Labs to all of my friends.

Hi everyone! I recently got my test results back from Function, but my PCP isn’t really interested in doing a deeper dive into them or looking at the bigger picture.

So I started looking for practices in my area that take a more proactive, preventive approach to care. I ended up calling at least 10 places before I found one that was actually willing to provide this kind of care.

I’m curious if anyone else has run into the same issue. If there’s enough interest, I thought it might be useful to put together a list of practices that genuinely offer this type of preventive, comprehensive care so others don’t have to call 10+ places to find one.

Would love to hear about your experiences and any recommendations!

Is there any doctor evaluating the results ? Do they offer any diet / supplement suggestions ?

Is there a forum moderated by a healthcare professional ?

Can I get function health test in Albany NY?

I am prepp

Does anyone have any suggestions does anyone have any suggestions of which add-ons should absolutely be added to the initial blood work?

35M, 6’0”, around 195-198 lbs right now, been lifting and training regularly for years, trying to get down to a lean 185. No history of hypertension, no chest pain or angina, not diabetic, no personal history of any heart disease or previous cardiac events. Family history is really just my grandfather who lived to 93 and had a pacemaker put in sometime in his 70s, nobody else on either side had a heart attack or stroke or anything like that, and the rest of my family doesn’t take care of themselves diet or exercise wise and seems totally fine.

This is my first full panel like this, no previous history to compare trends against, so I don’t know how long these numbers have actually been elevated.

Full panel:
Total cholesterol 181, HDL 46, LDL 116, triglycerides 90, non HDL 135, total chol/HDL ratio 3.9, ApoB 102, Lp(a) 184 nmol/L, LDL particle number 1091, LDL small 182, LDL medium 244, LDL peak size 220.4 angstrom, HDL large 4056, labeled LDL pattern A despite the small/medium numbers being flagged high

hs-CRP 7.1, but I got this draw after about 4 hours of sleep and a hard training session so I know this one is probably inflated and I’m getting it rechecked under normal conditions before reading into it
Glucose 91, HbA1c 5.5, insulin 7.0, leptin 2.0

Testosterone total 513, free 90.3, estradiol 34, SHBG 23, DHEA-S 290, prolactin 19.4 (again drawn after bad sleep and a workout so probably inflated too)
TSH 3.05, free T4 1.1, free T3 3.3, thyroid antibodies both negative

ALT 15, AST 15, ALP 51, GGT 19, total bilirubin 1.4 (this one runs high consistently for me, pretty sure it is Gilbert’s syndrome, confirmed with a genetic test)
BUN 18, creatinine 1.13, eGFR 87

Vitamin D 64, ferritin 119, homocysteine 10.3, zinc 67

Omega 3 total 6.7%, omega 6 total 34.6%, omega 6/3 ratio 5.1, arachidonic acid/EPA ratio 12.1

Diet the last year or two has basically been a pound of ground beef, 3-4 eggs, and a lot of rice almost every single day because it’s easy and hits my protein numbers. I know that is probably a big part of the ApoB and LDL story and I am already cutting the daily ground beef out.

Also ran my raw DNA against this and the Lp(a) number is confirmed by the LPA gene variant (rs10455872), so that part isn’t going away with diet, it’s just genetic. APOE came back 3/3 which I think is the neutral version, not the bad one.

Getting a coronary calcium scan and seeing a cardiologist regardless of what anyone says here, this isn’t a substitute for that. But with barely any family history behind me except a grandfather who lived to 93, I’m trying to figure out how seriously to actually take the Lp(a)/ApoB numbers versus how much the family track record should count for something.

Also curious what people think about the LDL debate in general, I’ve seen people say it’s the whole ballgame for heart disease and other people, especially in the longevity and testosterone spaces, say it’s overrated and even correlates with better cognition and hormones as you get older. Not trying to talk myself out of caution, just want a range of opinions. Same with statins, I don’t think I’m anywhere near needing one yet but curious if anyone with similar numbers ended up going that route or did something else instead.
