I used it for a year and the tests were good and thorough. Probably would've given a 3 or 4 star review but...customer service was great helping me with an issue. So its a 5 star. I moved out of the country and they worked with me on my subscription for a fair exit.

LOVE Function Health! While the amount of information in the test results is a lot to go through, it is correlated for easy understanding. You get waaaay more useful, helpful info than with regular Dr.’s results.

The experience has been excellent all-around. From the blood draw at Quest to the reporting from Function Health, it's been great. The reports have been very thorough and insightful, beyond what I expected. If you are concerned about your overall health, this is an excellent investment.

Heidi
I have requested, what I believed to be important, blood tests from my PCP and was told no. This health screening caught problems and gave me solutions and I have made several life changes. My health goals are a greater priority and annual testing gives me feedback on my progress.
