The ranges and health groupings were understandable. The Doctor AI summary was reasonable for my data.

Everything great except trying to print out a concise and clean report for my doctor and other results for myself. The data is great but some website designer could do a better job of making a summary doctor report more easily findable and concise and other data more printable so it doesn’t end up on a zillion pages.

Very easy and fast to get the blood draws. I love the app to quickly look at everything and often. CONS: I found it difficult to find how to print it out or be able to send digitally to my doctor on both the app and on my PC. Dr. Report took months

The blood tests etc are good - it is painful to use the results with a doctor as the results cannot be uploaded electronically to Apple health or any EHR

The blood test checkin was very easy. i would give 5 stars if there was an easy way to send my results with the notes to my doctor.

I liked everything about the service except one aspect: I do not like there is no choice to not sign up for automatic renewal. One should be given a choice rather than having to go on the site and cancel prior to renewal.

I understood the results better than the first test. It is a lot of information for a normal person and I do appreciate the facts. My markers improved which is great! I wish my Dr. was more receptive to looking at the results and giving me guidance on how to improve my markers. She looks at them and just says they look good. My goal is to keep my health in check and make improvements as I age.

This was my first time using a service like this and I enjoyed it. I do wish that it was a little more oriented towards my goals, but I do really like the insights and explanations of the different tests.
