While I really like how quick I received my results it is rather costly with all the add-ons, which I didnt do as it was already too expensive. I will do other add-ons later at a place with better cost options. I also appreciate the summary I received a couple weeks later but still didnt really understand significance of certain results, but will bring up with my chiropractor/nutritionist.

Expected better analysis/correlation of blood markers using AI. Lacking an added value.
