Chain of Custody DNA Collection in Gallatin, Tennessee
Chain of Custody DNA Collection, Explained
A DNA result is only as trustworthy as the trail behind the sample. Chain of custody is that trail, written down at every step.
Overview
How chain of custody DNA collection works
Chain of custody is a documented record of who handled a DNA sample, when, and how. It begins with verifying each participant’s identity and ends when the laboratory confirms the seals arrived intact.
DNA Paternity Solutions performs chain of custody collection in Gallatin, Tennessee for legal paternity, immigration and other cases where a third party must be able to trust the result.
The difference between a result and evidence
Without a custody trail, a court or agency cannot rule out a swapped or contaminated sample. With it, the result can be relied upon by people who were never present at the collection.
