When I got to Quest for my follow up blood work, Quest didn't have the order. I texted someone at Function Health & it was taken care of in minutes. (At 7:10 AM!!!!)

Communication was great. The scheduling and follow ups for the testing was timely and seamless. Clinician's notes were insightful and provided helpful information.

Q. E.
I love the explanation of the results and the food and supplication suggestions. However I didn't get any results telling me about my progesterone levels. But overall I am pleased with the service.

I found Function Health just when I needed it! Their relationship with Quest Diagnostics and the super easy process made my decision a no-brainer. I compared other company's offerings and pricing and picked FH because 100+ markers and Clinician notes for $365 is a very good deal. I was looking at Quest pricing on my own before I found FH and my total was over $800 but didn't come close to 100 markers. My blood tests results have changed my life. I was using Claude to help me understand why I was feeling as I did when I came across Function Health. Among other things my results showed inflammation and food were problems for me. Tomorrow will be 4 weeks on low histamine foods (and food prep) and the visible change is remarkable! My rosacea has calmed, my digestive system has improved (no bloating, gas). I thought my 4x week salad dinners were healthy. Not so much. Some of the ingredients exacerbated my already inflamed system. I took my 100 marker results to my PCP which resulted in looking deeper into some issues the results found, approval of my food/supplement changes and they wanted to read my Clinician Notes! Easy access to blood testing and other doctor ordered tests will change the US Healthcare system. Most importantly it will change our lives by empowering us with knowledge to help us make healthy changes and enable us to talk to our doctors on a new level of detail.

Amazing and seamless experience from the blood draw to reports delivered to my phone & email. Accessible information and data in language that is understandable.

Everything very smooth and professional but very little “after the tests” interaction. Felt like it was up to me to read and diagnose. The “before the tests” experience was intense hand holding and explanation and reminder heavy
