Nate
Great to have such deep insights into my health, but I wish the takeaway summary was a bit more actionable. Also, it doesn’t integrate with Apple Health, which I’d need to easily compare to historic results.

Luis Brito A.
So far so good, very informative and I found that when compared to paying for tests elsewhere the value for the money is significant. I like having more than the regular panels to see where all my markers are sitting.

Everything was really good first round. My 2nd annual test actually covered much less then the first one. Everything else was add on. I did purchase sopme add ons and this is the awful part. They didn't get included in my lab appoitment so they were skipped. Now I have to get re poked at a lab. This not only takes time off my work to do but the fact one of my tests is celiac I must eat gluten for 2 weeks. I got really really sick preparing for the last test so now they will not refund me for that because I really do not want to be sick again. I am looking at GoodLabs and Superpower now.
