The overall value of the laboratory tests, that are not normally ordered by your primary care physician, is incredible. I learned so much more about how these labs impact my health. There is so much more information and the clinical notes pull it all together. And it's an amazing economical value, too!

I am very impressed with my subscription to Function Health so far. In addition to the general testing I purchased the add-on GRAIL Galleri cancer detection test as a way to supplement my ongoing oncology care with additional data. I have ovarian cancer and a genetically increased risk for getting certain cancers, and I felt this test offered some additional peace of mind in my situation. The amount of information provided for each individual result is really remarkable, and to have an explanation of the result to reference in the palm of your hand is priceless. Reading the thorough "why this matters" info provided with each of the test results, I learned more about some things I already knew about myself, and extensive details that I didn't know, particularly from the Alzheimer's add-on tests. I am looking forward to the follow-up testing to see if any changes I made have been helpful.
