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.

The bloodwork appointment was easy, everything at the lab was seamless and efficient. Results came in quickly, and were easy to understand. The analysis of the results was extremely detailed and very helpful. I learned a tremendous amount about my health and how I could improve it. Highly recommend!
