The results came in very quickly, took a couple of days, and I am very pleased with this product. If I need it again, this is what I’ll get. I will definitely recommend this to anybody that needs to do a DNA test.”

  • A Company Worth Choosing

    "I recently needed to order a legal paternity test. What I like about Paternity USA is that they answered all of my questions over the phone and the customer service representatives were very patient. They did not hard sell at all and the representative via email was professional as well. The exams were done relatively seamlessly in two different states. The email results came back promptly with a notarized, mailed document a week or two later."
