I was very impressed by how easy and fast both the bloodwork was and the results. I visited a specialist at a University hospital and your results helped immensely with my meeting. The AI generated suggestions were right on with what the drs suggested!

I was very impressed with the lab report and the extensiveness of it. I took it to my doctor and we worked through it to come up with a good supplement program I would not have otherwise done. I now feel like my supplements are being custom tailored and optimized for my health. I am recommending Function Health to family and friends. Thank you!

This was ultimately a less expensive way for me to check in on my health in America even with really great health insurance through my work. I am pretty uncomfortable with how much ai is utilized in this company, but i suppose that’s how they can do this for a lower price. i was however extremely put off by having to click no to 10 (or more) super pricey add ons to complete my order. please condense this into one page! the ai bot who created my Clinician Notes misread my information originally and gave me advice as if i had abnormal hormone levels and this was signed off by a doctor, but a few weeks later they realized a mistake was made and revoked the notes and created new ones. that was weird but okay. the ai seems pretty trained to see veganism as bad for your health and tried to tell me to never eat soy. that was really icky and misinformed. ultimately this was worth it and im really thankful to have the knowledge this provided me and am now on a protocol with my doctor to address my two deficiencies!!

They need to disasscoiate with Quest Diagnostics - getting /going to an appointment there is so ghetto. I also don't feel like I got any answers on my core issues (osetoarthritis and dimished ovarian reserve) - just bloodwork, but no answers on what to do for my unique issues. I probably could have gone through health insurance to get the seame lab results so not really sure of the value, though I do enjoy the biological age feature for fun and learned a bit more about my chloesterol in depth,
