DNA banking is the collection and storage of a DNA sample for safeguarding and future use. Most DNA testing companies offering DNA banking services provide DNA storage for 15 to 20 years.
When is DNA banking used?
DNA banking is a preventative service for potential needs for your DNA samples in the future. Banked DNA serves as a quick source of identification for unexpected situations, such as searching for a missing person, identifying individuals in high-risk positions (such as soldiers, public safety officers, and overseas contractors), and protecting personal estates from illegitimate claims.
Many times, DNA banking is coupled with genetic profiling to establish a useful resource for genetic identification.
Who is typically involved?
Anyone can participate in DNA banking. Oftentimes, parents will collect and bank their children’s DNA to serve as a permanent record of their genetic identification in case they need this resource. Other typical participants include professionals in high-risk occupations and members of families with medical histories of inherited diseases.
How are the samples collected?
Samples for DNA banking can be collected in several ways. The most common and painless method is the use of buccal swabs.

What is the typical price range for DNA banking?
DNA banking is one of the least expensive DNA services, costing between $100 and $200.
What else should you know about DNA banking?
Most DNA banking is performed using the chain of custody process to ensure that your genetic identification will be court admissible for any potential need in the future. You can learn more by visiting the Do you need a chain of custody test? page.
