What is a COC form?

COC stands for Chain of Custody and it is the form a licensee gets from FirstLab and is required to present to the collection site in order to do a drug screen. The COC documents all aspects of the drug test, the name and identifying ID number of the licensee/individual providing the sample, the type of test/sample (usually urine or hair), the date, time, location and contact information for the collection site, name and signature of the collection site representative, whether the test is observed, what option is selected to be tested, the seal used to seal the specimen bottle, and all details pertaining to sending the sample to the appropriate lab for testing. The COC form stays with the specimen during the entire testing process because it has all of the identifying information.
