  1. What are buccal/mouth swabs and why is this not a blood test?
    Your DNA is the same no matter where the sample comes from. Testing cells taken from a swab will give you the exact same results as cells taken from your blood.
    A buccal/mouth swab resembles a cotton Q-tip. When you rub the inside of your cheek with a swab, your cells stick to the fibers. This is a painless, non-invasive method of collection that is comfortable for children and adults, and can even be done in the privacy and comfort of your own home.
  2. Can I just store my DNA at home?
    There are several reasons why you may not want to do that. DDC has a safe storage environment for your DNA sample. We seal the DNA sample in such a way that the DNA will be preserved. You cannot do this at home. Furthermore, our facility is protected both from the elements and from any possible theft or tampering.

  3. How long does DNA last?
    If sealed and stored correctly, a DNA sample can last for an indefinite period of time.

  4. Can anyone get my DNA without my approval?
    At the time of collection, you are given the opportunity to provide us with the names and social security numbers of persons you authorize to have access to your sample. You may add or remove names from this list at any time. Your DNA can only be released to you or the people on your list. Also, a sample can be released through court order.

  5. Is this confidential?
    Yes. Our DNA Banking service is strictly confidential. No one will know that your DNA is on file at DDC unless you tell them.

  6. What if I want my DNA from you in a few years (or at any time after it is stored)—can I have it?
    Yes. We will release the DNA sample to you or to any other authorized person at any time it is requested. We will require an authorization form to be signed before we can release the sample.

  7. I've heard that it matters what probes are used for testing. Can you explain what that means?
    Probes are markers that look for specific locations in your DNA. DDC uses all 13 probes the FBI uses to identify people. These 13 probes are considered the standard in the human identification industry.

  8. What is an allele sizing?
    An allele size, simply put, is a number that represents the size of your DNA at a specific location on your chromosome.

  9. If I need DNA testing down the road, can you do that for me?
    Yes. DDC offers a wide variety of testing options. Whatever your situation, we can help.
