Kathy
I paid $315 for tests that would have been covered by insurance, thinking I would speak with someone about the results, and instead it is just a chatbot. Feel taken.

Some of my blood tests needed to be redone due to lab foulup. You did not wait for me to reschedule prior to having your clinician review/write summary. Therefore I do not have a complete picture of my overall status. I will also say your incorporation of AI creates gaps in your communitations

I think this is a great deal. I got it on sale so I’m happy with the price. The only thing I don’t like and the reason I gave it a four score instead of five is the fact there’s so many up sells on different blood tests, and they are expensive. There are no price lists for any of the tests unless you are a member so until you become a member and pay for a membership for the initial Blood Testing panel, you don’t see the pricing for the other panels like I said, they are expensive. I think the initial test to give you an idea where to go is great. A doctor breaks it down for you and tells you what’s your strong points and what’s your weak points and what you may need to do to improve, they are very good and very accurate. I really wanted to do the full Alzheimer’s test and the flu cancer test, but those two together were about $1300or $1400. Yes I would recommend it to a friend.

Sarah
Really appreciated the full body - full picture approach to blood work. Helped me make changes to eliminating some foods that were causing a lot of discomfort - without just guessing and after the improvements were made to my diet I felt much better and my second bloodwork test showed it!
