Love having a more complete idea of my health than regular doctors provide. The final analysis and food- supplement guide is great!

Well organized and friendly staff at the Diagnostic center. Only issue is the reporting sucks for sharing with other health professionals.

I think everyone can benefit from a thorough review of their bloodwork. The clinician notes break everything down and explain what it all means. They also let you know if there are things that require follow up and why they matter. Excellent value.

I appreciate getting more in-depth information about my blood markers and knowing what is in range and what still need improvement. I would recommend to those who want a more in-depth look at their own personal health markers.

It took a few tries, but I finally found someone at Function Healthwith whom I could connect to help me navigate the site. That changed everything. The clinician notes are amazing with insights that few clinicians would be able or have the time to provide in a standard in office evaluation.
