Now that you’ve learnt how to create an Assignment, add and collect samples, the next step is to create an Assignment Chain of Custody (COC). Here’s how to do it:
How to create an Assignment Chain of Custody
Open the Assignment with collected samples that you want to create a Chain of Custody for.
Navigate to the Obzerv phase and select Sampling.
You will see the Sample. Click the progress circle for the sample reference numbers you want to create a COC for.
You will get stopped if you have not set a default laboratory office for your samples. If you’re using a Laboratory that has multiple drop locations, Samples can be sent to multiple offices. To learn more, read Adding an Office to your Laboratory.
Click Continue at the bottom of the screen.
You will be sent straight to the Relinquish screen. Add the Receipt Number and Signature. These are optional entries and based on your organisational compliance process.
Click to Relinquish.
The Review page will open. Click to view the COC pdf, References and Containers included on the Chain of Custody.
Click the X to exit the Create Chain of Custody workflow.
You have relinquished the Chain of Custody. Take note of the Chain of Custody Id1.
Remember to Complete the Assignment to submit the eCOC to the laboratory.
You have created an Assignment Chain of Custody! The electronic Chain of Custody will be sent to the laboratory when the Assignment is Completed or when the Samples are Approved.
1The Chain of Custody Id is an automatically generated, human readable number which identifies an electronic Chain of Custody (eCOC) and matches it to the esky of samples. The esky will carry a simplified Chain of Custody, called a sample submission receipt, to allow lab technicians receiving and processing the samples to correctly identify and match samples to their respective eCOC.
The COC Id is created when the COC is created in Obzervr Capture. For your information, it is a twelve-digit number (i.e. 1234-5678-9012), which is made of the following:
1234 – the day and month of the COC;
5678 – a user specific ID;
9012 – random four digits to make the COC ID unique.
