Why fight with your doctor or insurance company to get the tests you want done? Skip the gaslighting and empower yourself. It's affordable and easy.

Heidi-Marie S.
I was really pleased that FH was able to reduce the price of their offerings while providing the same service as last year. The opportunity to obtain additional testing is also impressive. It took considerably longer to get the clinical assessment of my results but that wasn’t a problem. I would have appreciated a more in depth recommendation for lifestyle changes regarding my cardiovascular health as I’m already pretty maxed out in that area. I’ll be taking these results to a credible naturopath for their input as well. FH is a great screening tool to take more control of my well-being. No more waiting on my HMO for random assessments. Thank you FH.

Xenia
I’m absolutely obsessed with Function. It tested biomarkers I had never even thought to check before, and for the first time I feel like I have a truly comprehensive picture of my health. I genuinely recommend Function to anyone who wants to be more proactive about their health and get insights that go far beyond standard lab work.

Lois
I am really valuing this experience thus far. It could have been a little better if I had understood what to expect at my mid-year (not a full retest, but a partial retest and not a full blood draw but a light one).
Response from Function HealthOct 4, 2026
Thank you for sharing your experience, Lois. We’re glad to hear you’re finding value in Function, and we appreciate your feedback about setting clearer expectations for the mid-year visit.
LRK
I had a great experience with Function Health. Easy to use, the app is convenient, scheduling is convenient, and customer service was helpful. I now know a few areas of my health to focus on, and I love having that data readily available! I've already referred 3 people.
