DNA Banking Frequently Asked Questions
My family and I are all relatively healthy individuals. Why should we bank our DNA?
We all carry at least hundreds of DNA sequence variants which adversely affect our health. There is no such thing as a genetically perfect person. The fact that each of us inherits half of our DNA from our mother and half from our father makes the practice of medical genetics about families rather than just individuals. Making your DNA available for testing, even after your death, can help improve the health of your family members. Correct interpretation of DNA test results in a family member may only be possible through testing of your own DNA.
How much blood is required for DNA Banking?
The DNA Banking kit contains one 10 ml tube for sample collection. Five to ten milliliters of blood (approximately one to four teaspoons) should be drawn to provide adequate volume for DNA extraction.
Is blood the only sample type that DNA can be extracted from for DNA Banking?
No. DNA can also be extracted from cheek cells, saliva or other tissues. Blood is the preferred specimen type due to its high DNA yield, usually always giving you a significant amount of DNA for multiple testing. There may also be an additional charge for extraction from specimen types other than blood.
Where is my DNA banked?
After extraction, your DNA is stored in at least two secure freezers at two or more separate locations.
Who has control of the DNA sample?
You, as the depositor, are in complete control of the DNA sample. You have the authority to request that sample be withdrawn, transferred, tested or destroyed. Control of the sample will be shifted to your appointed representative in the event that you become incapacitated or after your death
Will my personal information be kept confidential?
Yes. All of the information you provide when banking your DNA is entered into a secure database.
I might be interested in DNA Banking. What should I do first?
Print out the DNA Banking Agreement (pdf). The Agreement contains full instructions and much more information regarding the DNA Banking process.
For DNA samples banked on a person (aka Depositor) who subsequently passes away, who is able to withdraw the deceased Depositor's sample and who can order clinical testing?
The listed Representative(s) for the Depositor can use our Withdrawal Form to request the banked specimen be pulled for clinical testing. In cases where the Depositor has passed away, testing can be ordered by either the deceased Depositor's healthcare provider or could be ordered by the healthcare provider of the next of kin as long as the legal Representative signs for the withdrawal. Since the Depositor is no longer living, the next of kin/Representative can utilize whichever healthcare provider they wish to facilitate the testing process. All clinical testing performed at PreventionGenetics must be ordered by a qualified healthcare provider.
