The Chain of Custody is the reference point for our work here at Armstrong Forensic Laboratory. It tells when you released the sample to us, how you have identified your samples, the types of testing you want on each sample, and many, many other things. When it comes to the formatting of your chain of custody there are many different ways that you can approach the problem. The easiest solution is to download the provided Chains of Custody from our website. At the bottom of every page at, there is a Downloads Section, and all the chains of custody are available there for your convenience. Some of our clients also have their own chains of custody that they send with their samples and these work as well!

The information on the chain of custody is what is most important to us. If you want to send your sample with the relevant and necessary information on the corner of a restaurant napkin, we will take it! A chain of custody will be accepted as valid as long as it contains all of the necessary information for us to process your request upon arrival, and follows the the rules of evidence handling. If it doesn’t contain the necessary information, then we will contact you to get that information, and make certain you and your samples are taken care of.
