Having access to such extensive bloodwork has revealed many issues that have never been discovered from previous minimal testing by my doctor. I eat well, exercise and take no medication and have bloodwork done every Spring and have never had my doctor express any concerns. I did the Function testing on October 31/25 and had 10 of my 15 heart markers out of range. I had 5 other markers seriously out of range(total of 20 out of 120 tested). My thyroid is still functioning at normal levels but I have Hashimoto’s disease (autoimmune disease)that will eventually impact my thyroid function. I love the AI component so I can ask very specific questions without having to input my test results. The recommendations for supplements and dietary changes that I am now following will hopefully bring some of my out of range markers closer to normal. I was very surprised and initially disappointed to see that I had 20 biomarkers out of range but I am now looking forward to retesting in a few months. I am Canadian and spend 4-6 months a year in Florida. Our health care system is very stressed with many people are without a family doctor and you may wait years to get one. We have moved twice in the last 10 years and my family doctor is now 2 hours away and it takes weeks to get an appointment. After comparing the thoroughness of the Function testing to my testing done by my family doctor in the Spring, my husband and I joined a private NP practice. On my first visit I shared my results and the supplements that I was taking and she was very impressed and wanted to retest a few markers sooner and ordered some other tests. We have told our friends and family(American and Canadian) about the incredible value of becoming a member of Function Health.

Thank you for sharing such a detailed experience. We’re glad the testing helped uncover important insights that hadn’t surfaced before and that the AI chat has been useful in answering specific questions along the way. It’s encouraging to hear that you’re taking action with nutrition and supplements and looking ahead to retesting. We truly appreciate you sharing Function Health with friends and family and are grateful for your trust.
