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.

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.

All of the testing was easy. I love the data and feedback I got from testing. The feedback from the doctors was helpful and is a great way to stay on top of my health. I would love to see a reduction on MRI fees in order to take my health to another step.
