Results came back quickly. Good detailed information behind each one. The only thing that I was unclear about were the genetic/DNA results that did not have a range and it wasn’t cleared to me if the results were positive or negative, good or bad.

Hard to get hold of the support. I have been trying to get my test once again, no real support in there to help until it got passed, they attempted to a chanrgeback to get there $36 , then no communication after that even i was able to see it happen in my bank account. and until now, the retest is not something they offered yet to fix their Tech stack and non communication on deadline !
