I was so excited to FINALLY find a source for intelligent blood work and evaluation!!! I didn't have a Quest Lab close to me so they helped me find one close to our upcoming vacation location. The evaluation and recommendations were SO INSIGHTFUL and helped me find a functional health doctor. I was worth every cent!!

Scheduling tests is super easy, test options are amazing (so many!), and tech support has been outstanding when I’ve needed it. I’ve shared results with my doctors which has been very helpful in developing my treatment plan.I will continue to use Function Health going forward.

Im very please with everything you do. Your knowledge and promptness to respond in every situation has being of great help for me. I loved the super complete report of my blood work with all explanations about what everything meant and list of what foods to eat including suggestions about the supplements to take to lower my cholesterol . Help when I had questions and kindness all along. I will definitely continue to recommend Dr Hyman and his wisdom. Thank you, Ada Saenz Urbinati

Function Health is the solution to a better understanding of my health metrics that I didn't even know existed before I started following the renowned cardiac surgeon, Dr. Jeremy London! ;)) Not only does Function Health offer one comprehensive test each year (100+ biomarkers over two days), but there's also a mid-year retest (60+ biomarkers) and also the ability to take tests for any of the markers at any time of the year as often as we'd like for a per-marker fee along the lines of $19 for things like Hba1c, insulin, apo(b), and even the standard lipid panel (and there's advanced lipid markers for those interested in retesting those more frequently as well). Function Health is a complete game-changer for me and makes me so much more excited about my health, and actually has dramatically improved my health as well due to the ability to take bloodwork results and then discover how to improve certain marker outcomes by utilizing Google and it's awesome AI-powered data. Follow Dr. Jeremy London on social media to get a $100 discount for the first year to see if this is something you'd like to incorporate into your life as well!
