Best DNA Test Options For You
Siblings
Discover if siblings share the same father or if your children are from the same man, or confirm a possible relationship discovered through ancestry testing. The mother of the child is also encouraged to submit her DNA as well to help strengthen the results, but her participation is not required.
Maternity
Maternity DNA testing determines whether the woman tested is the biological mother of the child tested. It works like a DNA paternity test, except this analysis compares a child’s DNA profile with their mother’s. Even if the father is not tested, DDC can prove whether the child’s DNA matches the mother.

Frequently Asked Questions
Where can I take my DNA test?
Your DNA collection method will vary based on the type of test you need. Some tests allow for results to be collected at home, while others may require results to be taken at one of our 5,000 testing locations. Please refer to your test’s guidelines for details on where you can collect your DNA.
Is a mother’s DNA required for a relationship test?
Many relationship DNA tests can be completed without the mother’s DNA; however, we recommend including the mother’s DNA if possible to increase the possibility of a conclusive result.
What type of samples do you use?
DNA is collected by test participants using cheek swabs (also called buccal swabs). Cheek swabbing is a quick and painless way to collect cheek cells containing DNA. This is not a saliva test.
How will I receive my results?
Non-legal test reports can be downloaded from your secure online account on our website. For legal reports, we can email or send a hard copy to the address that you specify.
When will I receive my test results?
Depending on your desired test, you may be able to receive results in as little as 3-4 business days after your sample is received by our labs.
Can I use my test results in court?
If you want to use your test results for legal purposes (child support, custody, etc.) you will need to use a Legal DNA test that follows a strict chain-of-custody process and supervised DNA collection. Home test options are not eligible to be used for legal purposes.
Do you offer payment plans for your DNA tests?
We offer payment plans for some of our testing options. Speak with a member of our compassionate, knowledgeable customer service team and discover testing options and payment plans that are best for your situation.
