I have had relatives suggest Function Health for thorough blood screenings and I finally did it. Now my functional doctor has a better idea of where my health is and where it is headed. Seamless process and I really appreciated the formatting and explanations for each section.

I am so pleased with this experience! Not only was it easy to make the appointments, but the results came back so quickly. I did use the "chat" option to create a program using my results and that went so smoothly. I am going to recommend this to family & friends!

Ease of testing, exceptional coordination and communication (a 5 year old could follow). The availability and readiness of exams. It would be nice to update the intake information with recent doctor feedback so it's considered in future evaluations. Such as my elevated cardio biomarkers. I met with my cardiologist and he okay'd me to retest in another 8-10 weeks and then determine a course. He recommended Repatha but since my CT score was 0 - we agreed to push another 8-10 weeks.

I'm delighted with the ease of ordering and then the notes to explain the results. My Primary Care provider was impressed. These results helped us decide what direction to head for improved health . The nutrients section uncovered very low ferritin and iron when the Endocrinologist blood work showed normal levels. I've been exhausted! My provider did a blood draw for an EBV titer. We hope to solve another piece of the puzzle. Looking forward to seeing some improvements in 6 months!! Thank you for this service that is also affordable!

It was easy to make the appointment. Then getting the blood drawn was also easy. Once you get the results you start looking at what you personally need to do for health changes
