The Chain of Custody (COC)


Step 1: The collector must identify the donor, either through prior knowledge and/or a State/Government issued photo ID.

Step 2: Have the donor initial and date the specimen ID/security label in the corresponding section as shown in red below. The agency information section (towards the top left) should be pre-printed. If this is not the case or any of the information is incorrect, please fill in or update appropriately. 

Step 3: Begin filling out the Chain of Custody (COC) form with blue or black ink. Be sure to press firmly allowing the ink to show through to each copy of the Chain of Custody. The collector must complete the Chain of Custody form in its entirety. If the form is not fully completed, the specimen may be rejected or results delayed. 

Step 4: Ensure the specimen ID# on the COC matches the specimen ID# on the security label used for the sample. At this time you can advise the donor to provide the specimen.

Step 5: Collector should affix the specimen ID/security label over the device-first by centering the label over the top of the cap (as indicated on the label), than adhering the label flush down each side. This will create a security seal to ensure the specimen is not tampered with.

Step 6: The specimen is to be released to FedEx Express using the provided shipping label and supplies. FedEx Express provides the necessary courier.

Important: Every section of the Chain of Custody (COC) is very important and should be completed in its entirety to ensure fast turnaround time and accurate reporting!
