Karen
Clear understanding of labs to be taken and the results came quickly with good description of what each lab means. The value for the money is worth it.

Thank you for sharing, Karen. We’re glad the testing information was clear, your results arrived quickly, and the explanations helped make them easy to understand. We appreciate the kind words!
Kym
The tests took several weeks to complete but I was able to access and review them as they came in. The information in the summaries and evaluation of the results are well-written in an organized manner that makes understanding them easy, far more information than I have received from a doctor's visit because I can take my time to read and re-read as needed. I like the individualized AI Protocols and have experimented with refining them to my needs. Looking forward to continually referring back to them. The cost is reasonable and the tests are far more than I can get with standard Medicare/Tricare insurance, but the level of individualization and information available is priceless for older adults as well as the more youthful among us. I would like a way to print each test result category on its own page - summary and results for each in the same document. Copy/print does not seem to work unless I download a PDF then convert to a Word document to print separately.

Kym, thank you for sharing such thoughtful feedback. We’re glad the summaries, results, and personalized insights have been easy to review and revisit over time. We also appreciate your suggestion for a simpler way to print individual result categories, and we’ll keep that feedback in mind as we continue improving the experience.

It’s good and worth the cost. The app is intuitive and it gives actionable advice that is superior to the advice I was receiving from my primary care physician.

Carolyn
The app works great. The results came back quickly and the physician notes are a big help. There is a lot of information and the lab tests are for more detailed than what I get from a regular annual visit with my doctor. I feel I have a lot more information at my fingertips to help me know what I need to do for my best health. My only desire is an easy way to share the results and doctors notes.
