I am 62 yrs old and was having some issues with digestion, sleep, recovery, achiness. My naturopathic dr suggested I do the Function Health blood work. I at first balked at the cost but realized the treatment for any issue that crops up would be much more expensive. The testing was fast and easy. I got my results within 3 days and my notes with recommendations in 7 days. What a comprehensive workup!!!! Never got this with my GP!

Very good follow-up pre and post lab tests. In general I’m very satisfied with the service. It gives me the feeling that I’m in control of my own health and discovery with just the right amount of assistance. I think an upgrade to the service would be the ability to ask health questions post-lab tests to be able to tie some of the “dots” together. I understand not wanting to interfere with the person’s primary providers but the ability to ask some medical questions would help tie up loose ends. Overall I’m happy with the service and some of the things I’ve discovered.
