Thank you for your thoughtful review. We appreciate your support.
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.

We’re thrilled to hear the testing provided valuable insights and supported conversations with your doctor. We’re glad you found the process seamless and the explanations helpful. We truly appreciate your thoughtful review.
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!

Thank you for taking the time to share your experience. We’re thrilled to hear that the scheduling process, timely results, and AI Chat experience were valuable to you. We truly appreciate your recommendation and your support.
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.

Thank you for taking the time to share your experience. We’re pleased to hear the testing process was smooth and easy to follow. We appreciate your feedback about incorporating updated health information into future evaluations and will share it with our team.
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!

Violet, thank you for sharing your experience. We’re glad the results and Clinician Notes provided useful information to bring to your healthcare provider and helped guide your next steps. We appreciate having you with us and look forward to seeing what your next results show!
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
