CRG was EXTREMELY helpful, efficient and reasonably priced. I am 100% confident in the accuracy of tests and their ability to return results within an hour or two. This drug testing facility has helped me with preemployment testing, paternity testing and physical exams. I loved working with them! I would refer them to anybody who is looking for an individual test or for large quantities of testing. The staff was professional and I was always greeted by a friendly, professional staff member. I loved CRG Laboratories!
