All the reminders made the experience smooth. I lived the clinician notes at the end.

The results were good to see. I can make meaningful changes in the way I eat, exercise sleep, etc. I believe in the results and the information given. My concerns are mainly for the consistency of getting labs. My Milo peroxide was never done. I got 159 results out of 160. When I didn’t book this within three days the order was removed and results were given.
