One of my tests had to be redone, and the process for getting that done was seamless.

Nicoli U.
Fast results with details and clear explanations. I really appreciate the data point connection to my previous lab results. I also like the suggested ways to improve. Thank you FH. I am now 16.2 biological years younger and know what I still need to improve and now know how to continue to improve. Having clear data is the starting point of being intentional of optimizing one's health.

Everything is great from the locations for blood draws, the costs for the amount of bloodwork provided and the clinician notes and helpful information on supplements and foods to eat/avoid. The only issue I have is there is not an easy way to forward to this information to my primary care doctor, other than to print out the bloodwork and take it into the office. It's not a true problem, but would be nice if this bloodwork would connect to our primary care providers. I love Function Health!

Convenient and efficient. If not for the endless stream of 'upgrade' marketing, the experience would be commendable.
