A Custody and Control Form often called a CCF, is a five-part carbon copy form used to document the information pertaining to a drug test.  VLocity Group uses electronic CCF.  The driver gets an email with a pdf form attached, the collection site can scan the bar code on the form from the phone and it is all tracked electronically.   This has allowed us to cut the time down to most results coming back in less than 24-hour and eliminate 90% of the human errors.
