What is Chain-of-Custody- Baseline Testing and Training for Community
What is Chain of Custody?
This is a legal term that refers to the ability to guarantee the identification and integrity of samples from collection through reporting of test results. For the purpose of litigation, it is necessary to prove the legal integrity of all samples and data as part of the chain of evidence. Therefore, it is necessary to have and accurate written history for the sample. This history should include sample bottle preparation, bottle possession, handling, and location of samples and data from the time of collection through reporting. This can be conducted by using chain-of-custody procedures.

4. they are kept in a secured area, with access restricted to authorized personnel only.
The six steps in a chain-of-custody process include:
