Perfect for my needs. Physician notes were helpful, and love that it is based on optimal, not just accepted average ranges based on an overall unhealthy population.

I highly recommend Function Health and am happily renewing this year. Even though my insurance covers standard lab work ordered by my internist, Function’s basic annual panel goes vastly deeper than typical healthcare baselines. The AI-driven blood panel breakdowns are amazingly thorough, and as an early Oura ring adopter, I love being able to sync my wearable data into one central dashboard. My only critique is the "biological age" metric. While I was thrilled to test 18 years younger, the algorithm doesn't heavily factor in lipids. Knowing I have sky-high cholesterol, that score clearly doesn't reflect my actual cardiovascular reality. Take the biological age with a grain of salt, but for proactive health tracking and unparalleled data depth, this service is absolutely worth it.

I love all the tests that you run. They are so informative. The results give very in depth notes on what each test means. Everyone should do it.

After booking my body MRI with Ezra, I got timely notifications about the scan and how to prepare for this. The Madison Imaging Center had courteous and knowledgeable staff from the front office to Rosie, the MRI tech. The facility was immaculate. After I shared with Rosie about my claustrophobia, she kindly broke the 30 minute scan into 3 sections and was very affirming to get me through this. I was able to take a brief break between the sections to settle and mentally get ready for the next part of the scan.

The platform is a reliable one-stop shop for comprehensive labs and turnaround time on labs continues to improve. Advance screening at his level vs. waiting for symptoms is the reason to do it.

I had a very good experience from the scheduled blood draw to navigating all the many results. My primary care doctor is very happy I am all hooked up with the program. Now, time to do a few pointed deep dives and I will be on my way to peace of mind about my body. Thank you function for helping me feel like I can.
