Alternative Sample DNA Testing in Gallatin, Tennessee
Alternative Sample DNA Testing When a Swab Is Not Possible
A cheek swab is ideal, but it is not always available. Personal items can sometimes carry enough DNA to answer the question.
Overview
How alternative sample DNA testing works
Alternative sample DNA testing extracts DNA from items other than a fresh cheek swab. Common examples include toothbrushes, hair with the root attached, used razors, and certain personal items.
DNA Paternity Solutions offers alternative sample testing for families in Gallatin, Tennessee, typically when a participant has passed away, is unreachable, or cannot provide a swab.
Realistic expectations about personal items
Success depends on the item, how it was stored and how much DNA survives. Some samples work well, while others may not yield a usable profile. Discussing the item before sending it helps set expectations.
The process
Handling an alternative sample

- 2

Useful details
