Debbie H.
I have done this for two years. Every June I have to spend time coercing them to finish and provide the clinicians report. My husband gets his within 3 weeks but mine seems to take 6 weeks. We take it at the same time or mine is a week earlier. I do everything asked of me and function doesn’t do their part. Every single time and I’m pretty healthy!

I've had an excellent experience with Function Health. Scheduling my lab draw was quick and easy, and the entire process was seamless from start to finish. My results came back faster than I expected, and the report was comprehensive. I especially appreciated the detailed insights and explanations that helped me understand what each result meant and where I could make improvements. It goes far beyond standard lab work and provides a clear picture of your overall health. Highly recommend for anyone who wants a more proactive approach to their health.

Maureen W.
I love that I now have trending metrics in my second year of testing. The insights and recommendations are detailed, and I trust they come from latest research. The fact that I was able to buy the Apoe gene test for a substantial savings was a bonus
