When I first heard about Function Health, I was intrigued by the idea of a platform that goes beyond the typical blood panel and gives you access to 100+ biomarkers—something usually reserved for elite athletes or concierge medicine and typically costs thousands of dollars out of pocket. This is different. For $499 (with optional add ons), you can utilize this service to get more data on your overall health and wellness by testing a wide variety of biomarkers via blood and urine samples.  

So, I signed up, got my labs drawn, and waited for the results that would either confirm what I suspected about my health or open my eyes to things I never knew were going on. Spoiler alert: It did both.

How it works

If you are a female, the testing is cycle day specific. Your first blood draw must be between days 3-5 of your menstrual cycle (you cannot do this exam if you are pregnant). The second exam is a blood draw and a urine sample which should be within a 10 day window after the first blood draw. 

When I went for my labs, my phlebotomist mentioned to me that Function is becoming exceedingly popular and that she sees at least 1 patient a day in her lab who is taking control of his or her health with this platform.  It’s pretty amazing to see that so many people want to learn more about their bodies and how to improve. 

When the specimens are evaluated, the results populate on the function health website as they are ready. They are categorized in terms of what system or role the specific biomarker has within the body. You may see an example of the thyroid below: 

Each biomarker has an explanation behind it as well:

One of the biggest things I appreciated is how Function breaks everything down in a way that’s easy to understand without dumbing it down. You’re not left with just numbers—you get a real sense of what’s optimal for you. I could see where I was thriving and where I needed to course-correct. It validated so many of the choices I’ve made (like avoiding seed oils and prioritizing organ supplements, grass fed meats, clinical collagen and raw dairy), but it also gently highlighted some areas I wouldn’t have thought to look at.

A Personalized Health Map

When you see your results populating through the Function Health platform, it doesn’t just dump numbers on a screen—they organize everything into categories such as heart health, metabolic health, immune function, hormones, toxins, and even biological age. The dashboard is clean and surprisingly easy to interpret. It showed I had:

  • 116 total biomarkers analyzed (via blood and urine)

     

  • 103 in range

     

  • 13 out of range

     

One of the most validating moments? Seeing that my biological age came back as 16.8 years old! That is 16.4 years younger than my actual age at time of testing (33). That felt like the best high-five from all of the major lifestyle changes I made over the course of the last 3 years.

What Surprised Me

Despite feeling generally well and my bloodwork being excellent, I had a few areas that raised eyebrows—especially around autoimmunity. My ANA panel was all over the place:

  • ANA Screen: Positive

     

  • ANA Pattern: Nuclear, Homogeneous & Speckled

     

  • ANA Titer: 1:320 and 1:80

     

  • But interestingly, Rheumatoid Factor was normal, and my inflammation marker (hs-CRP) was low.

     

These aren’t symptoms I feel daily, but they hint at an underlying immune activation that I wouldn’t have known about without this level of testing. It’s a huge reminder that “normal labs” from your primary care doctor don’t always tell the whole story if you don’t have all of these biomarkers tested.

Am I worried about this autoimmunity? No (at least not yet). I have spoken about how I have endometriosis, in which many endo patients also have autoimmunity pop up in their labs.

What I’m Proud Of

There were a lot of wins in my report:

  • Metabolic health? Clean. A1c was 4.8%, fasting insulin and glucose in optimal ranges.

     

  • Liver & kidney? Healthy.

     

    • Female hormones? Balanced across the board. My endometriosis and PCOS sisters know how much of a HUGE deal this is.

       

  • Nutrients like Vitamin D and Zinc? Solid.

     

  • No heavy metal toxicity (huge relief, especially as someone conscious about environmental exposures).

     

  • And best of all: low inflammation and insulin sensitivity. My hs-CRP was 0.2 mg/L.

     

This confirmed that all the intentional choices I’ve made—ancestral diet, daily movement, sleep hygiene, low-tox living—are working.

Evaluation from Function Health

Once all of my biomarkers were in, a clinician wrote a full report based on my results. To be honest, much of the evaluation felt AI generated, but if that’s the case, they certainly had a clinician review the evaluation and customize it to an extent. 

Given my results and experience with Function Health, I chose to take a deeper dive into the findings with my dear friend, Tracey O’Shea, FNP-C — a Functional Medicine Nurse Practitioner and Medical Director at the California Center for Functional Medicine. We explored my labs further through their Functional Medicine Blueprint (Use Code MEG20OFF), a service that helps turn lab results into a clear, personalized plan for your health. 👉 CLICK HERE to see what we found and how it all unfolded.

Would I recommend Function Health?

Absolutely. Especially if you’re someone who values data, wants to take the guesswork out of wellness, Function worth exploring: CLICK HERE to skip the wait list with Function. 

Function Health gave me what I always wanted from modern medicine: feeling as if it was a collaborative effort using a medical practitioner’s expertise, rather than ‘do what I say because I have the credentials’ approach. It’s empowering to have this level of insight so I can be proactive, not reactive. 

If you’re someone who cares about longevity, energy, hormones, brain health, or just wants to take a more proactive approach to your wellness instead of reacting when something goes wrong—this is the kind of testing I recommend.
