My mother died of atherosclerosis four months ago. It prompted me to want to know what was going on in my body. I didn’t want to go back to a traditional Doctor Who in the past ask why I wanted a full blood panel. When I asked they said I didn’t need certain tests. For Literally a dollar a day. I got a full work up, and knew exactly what I needed to fix. It was quick. Results started coming in right away. The app adjusted frequently to show me my results and gave explanation’s for every test that they did. The AI function was great to give you real time answers to your questions.. I will definitely be signing up again next year and adding on tests this year to dial in my health if I didn’t sign up, I don’t think I really would’ve found out what was going on with my health. Also, the fact that they take HSA makes it super easy to sign up.

It is so helpful to have things explained and then to have suggestions for how to change or improve markets for better health. The explanations are very thorough. And I feel like the knowledge I have gained will help me change things that do not serve me or my health.
