I spent the last six months testing out a new kind of health membership that promises $15,000 worth of lab work for just $499 a year. No insurance or referrals required. It’s called Function Health, and honestly, I’m obsessed.

Function says they’ve cut out the middlemen like insurance companies, hospital billing departments, and unnecessary markups. What you get in return is access. Real, preventative healthcare access that most Americans simply don’t have.

‍Location: 

• You can get the $499 lab test membership with 160+ tests in 48 states. Lab visits aren’t available in Rhode Island, Hawaii, or Puerto Rico. Function Health has partnered with Quest Diagnostics and has 2,000 testing locations across the U.S.

• The AI-Powered MRI add-on is currently available in 100 locations around the U.S., with more locations adding fast. We chose to do the lab tests membership at home in Oregon, and added on the MRI during a trip to California.

To make testing accessible and affordable, instead of building their own facilities, Function teamed up with Quest Diagnostics to facilitate the lab appointments for them.

This is so exciting because it keeps costs low and allows you to get your lab tests done in 48 of 50 States. You can book your lab appointments directly through your Function Health dashboard, choosing a date and location that works for you.

Because there are so many Quest Diagnostics locations to choose from, we were able to book our appointments and get in that same week.

Before your appointment, you’ll receive a few prep instructions:

• Fast for 8 hours
• Stop supplements for 72 hours (to avoid skewing certain results)
• Avoid seafood for 48 hours
• Continue taking any prescribed medications as usual

‍

The Testing Process

‍

Your first round of labs happens over two short appointments within the same week. Each one takes around 15 minutes and involves 10 to 12 vials of blood, plus a urine sample. (Don’t forget to drink water beforehand, I always forget.)

I’ve gone to Quest Diagnostics for blood draws a dozen times, and they’ve always been quick, professional, and painless.

Your Health Dashboard

‍

‍

Once your samples are processed, your results begin appearing in your Function dashboard over the following weeks. I loved checking in every day to see which new biomarkers were ready and learning about each result.

For each of the 100+ biomarkers, you’ll see:

• Your personal result
• Whether you're in the optimal range, high, or low
• A “Why It Matters” explanation
• Self-care tips for maintaining or improving your levels
• Academic references and insights curated from top doctors and scientific research

‍

Your Biological Age, Explained

‍

One of the dashboard highlights is an estimate of your biological age, which reflects how fast your body is aging on a cellular level compared to your actual age.

This matters because accelerated biological aging is linked to higher risks of chronic diseases like diabetes, heart disease, cancer, and cognitive decline.

Function calculates this number by using a method based on the DNAm PhenoAge model by Dr. Morgan Levine, which estimates biological age using standard blood biomarkers such as glucose, albumin, creatinine, C-reactive protein, and blood cell indicators.

While this method provides a useful estimate, it’s not as precise as DNA methylation testing. Function acknowledges this and says they continue to follow the research as it evolves.

‍

Personalized Clinician Review

‍

Once your results are fully uploaded, a clinician from Function’s team will review them and leave detailed written notes inside your dashboard. If any critical results show up, they’ll give you a call.

I found the notes to be very thorough. The results were organized by category, like autoimmunity, blood, electrolytes, heart, immune regulation, kidney, liver, metabolic, nutrients, and urine.

Each section came with a summary and clear suggestions for improvement. There’s also a final recap outlining which results need attention and what steps to take.

‍

Your Action Plan

‍

Inside the dashboard, there is a section called 'Your Action Plan', which gives you personalized food and supplement recommendations based on your results.

For me, my “top 5 foods” are avocado, cranberry, hazelnut, walnut, and almond to support my cholesterol-related markers like LDL Small, HDL Large, and LDL Pattern.

‍

Follow-Up Testing

‍

Three to six months later, your membership includes a second round of testing, this time covering 60 biomarkers. You’ll only need one appointment this time (not two), and it’s included in the same $499 annual membership.

Once those results come in, you’ll get another round of clinician notes, and your dashboard will show a timeline for each biomarker so you can track what improved, declined, or stayed the same. In my case, I was glad to see that two of my biomarkers that were previously out of range had improved, and my biological age also went down.

Add-ons and Additional Testing

‍

Even without any extras, I think this membership already offers incredible value. Especially in the United States, where most health testing feels overpriced or out of reach.

But what makes Function Health stand out even more is that once you're a member, you unlock access to a full list of affordable testing add-ons you can purchase at any time during your membership year.

Here are just a few of the add-on tests I saw available inside my dashboard, along with their prices:

As someone used to the limitations of the American healthcare system, this level of access feels almost unheard of.

Instead of pushing your doctor to figure out what’s wrong or waiting for insurance to approve every single test, Function lets you see all the options and choose what’s relevant to you. And the pricing is competitive too, especially when you compare it to traditional healthcare costs.

AI-Powered Full-Body MRIs

‍

‍

One of the most impressive additions to Function’s offerings is its new lineup of AI-powered MRIs.

These scans now range from a 22-minute MRI for $499 that screens for over 500 conditions, up to the Full Body MRI Ultimate, which includes two 60-minute scans plus a CT scan for $3,999.

Here are all of their MRI options, and why this is so exciting:

‍

Function Health has just acquired the AI-powered MRI company Ezra, and Function came in they slashed prices. Before the acquisition, Ezra’s 22-minute scan cost $1,500. With a Function Health membership, that same scan is now just $499.

That means you can get both the 160 lab tests and a 22-minute MRI for a total of $998. When you compare that to other full-body scan providers like Prenuvo, Function’s pricing comes in significantly lower, and it includes far more value thanks to the extensive blood work.

I am very curious to see how other companies in the space respond to this price drop.

Our Ezra Experience

‍

‍

Ezra, now part of Function Health, is a full-body MRI screening service that uses FDA-cleared AI to offer faster scans. According to their website, Ezra has helped 6% of their members detect potential cancer early.

MRIs do not use radiation. However, if you choose a package that includes a CT scan, that portion does involve radiation, so it’s something to be aware of when selecting your option.

Fun fact, we had actually been trying Function Health and Ezra separately. We started filming our Function Health experience about six months ago, and then last month, we flew to California to try an Ezra scan.

At the time, we had no idea the two companies were about to merge or that pricing would drop right as we wrapped up filming, so this feels serendipitous.

We’d selected both companies on our own because we were impressed by what they offered. Now that they’ve joined forces, I truly think this might be the best health deal in America.

Back when we booked, we opted for their Full Body MRI Plus scan. That scan now costs $1,999 through Function Health or $2,395 on Ezra’s site.

This was before the $499 option existed, so if I had the choice today, I would’ve started with the more affordable 22-minute scan and possibly upgraded to something more comprehensive next year.

If you’re unsure which scan is the right fit for your situation, Function has a helpful section in their FAQs that breaks it down.

‍

To access the discounted Ezra pricing, you need to book through your Function Health dashboard. It will redirect you to the Ezra website, where you can choose a location and schedule your scan.

From what I saw when scheduling our scan, appointments typically book about three to five weeks in advance, depending on availability. However, Ezra seems to be adding new locations quickly, which should help improve access over time.

• Biological age estimates are intersting, but not exact.
  Function calculates your biological age using a scientific model based on blood biomarkers, which is helpful but not as precise as DNA methylation testing. My own estimate dropped from 18 to 14.9 after my second round of testing. It’s fun to see, but I take it more as a sign of improved results rather than a literal read on my body's age. I’d love to try a DNA-based version someday to compare.
  
  
• Facility quality may vary.
  Ezra works with partner imaging centers, and not all of them have luxury vibes. That mattered more to me when scans were priced at $1,500. At $499, I’m happy to skip the fancy extras and focus on the results. Some locations are nicer than others, so it may be worth checking reviews or calling ahead if comfort is important to you.
  
  
• Yes, they gave Cody pajamas.
  When we went, Ezra provided soft, branded pajamas for the scan that you got to take home. It’s not clear whether Function will continue offering this, but if lowering the scan price by $1,000 means skipping the custom sleepwear, I’ll take the trade.
  
  
• I wish there was an option for a clinician call.
  Function provides written notes in the dashboard, which I found really helpful, but I personally would love the option to pay for a quick call or follow-up if I wanted to discuss something in more detail.
