Michelle
Function makes keeping up with my health easier than requesting labs repeatedly from my doctor. If I got all these tests along with the corresponding doctors’ visits, it would cost me the same or more.

Signed up during Function Day! Easy to use app, great communication, easy reminders with all the information contained within, thorough details and information on lab results and the MRI through EZRA. Great pricing! Amazing overall!

LJ
Very impressed that results and clinician notes were available the next day! My results were all within range which provides such peace of mind. Definitely going to continue since doctor will never order all these tests. I did share the notes with her which she appreciated.

I am so grateful that I chose to spend the $3,500 to get tested for everything under the sun. It was the best decision I've made for my health, ever.

Miranda
So thankful for an affordable service that allows me to get a full picture of my health - I’ve spent years trying to figure out my source of joint pain and being able to see all biomarkers together actually led my doctors to an official diagnosis that probably would’ve taken several more visits and referrals to reach a conclusion! SO thankful!
Response from Function HealthAug 9, 2026

Erin G.
This is my 2nd year with the base testing offered by Function Health. I chose it for a better overall understanding of my personal blood work and what preventative steps would be helpful in protecting long term health. The testing, overview and suggestions have proving very helpful in directing health action items as well as possible long-term issues. It has worked for me and will continue on into 2027.
