Electronic Custody and Control Forms (eCCFs) are the electronic version of the traditional CCFs. This document is used for drug test ordering, specimen collection processing, and chain of custody documentation for workplace drug testing. The eCCF functions the same way as a paper CCF but speeds up turnaround times by up to 25% and prevents common user errors associated with paper forms. ECCFs eliminate errors due to illegible handwriting, incorrect procedures, using outdated or the wrong paper CCF, or inaccurate accounting/billing information.
