Test Options

Confirm a relationship even if a father is unavailable for testing, or confirm another relationship. Testing for both legal and non-legal purposes are available—call DDC for additional details.

Paternity

With paternity testing from DDC, you can find out who the father is and get answers to help you and your family move forward. Paternity testing determines biological fatherhood using easy, convenient testing methods that vary depending on your unique situation.

Get Started

Grandparent

When a possible father isn’t available for testing, one of the possible father’s parents can participate in testing to confirm the relationship. 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.

Get Started

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.

Get Started

Twins

Find out if twin siblings of any age are identical or fraternal.

Get Started

Aunt or Uncle

Determine a possible father through one of his siblings (your potential aunt or uncle). 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.

Get Started

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.

Get Started

Infidelity

If you suspect that a partner has been cheating, a DNA test can help you get answers. Using fabric you provide from underwear, other types of clothing, or sheets, our tests can confirm or deny the presence of male/female DNA.

Infidelity Test Options

Detection & Comparison Infidelity DNA Test: Detects DNA on the fabric (including for multiple people), pinpoints gender(s) of DNA samples, and determines if any of the DNA matches yours

Full Detection & Comparison Infidelity DNA Test: Detects DNA on the fabric (including for multiple people), pinpoints gender(s) of DNA samples, determines if any of the DNA matches yours, and conclusively tests for the presence of semen

Male/Female Lineage

Determine a relationship to relatives or ancestors through the male or female line.

Get Started

Native American

Many tribes require DNA proof of family relationships with an existing tribe member. With a specialized DNA test, you can establish paternity, provide supporting evidence for enrollment or disenrollment, reunite adopted children with their biological relatives, claim child support and other benefits, and more.

Best DNA Testing Options

  • Legal Test
    Legal DNA testing (also known as chain-of-custody testing) provides results that may be used as proof of relationship for child support, custody, immigration, birth certificate, Social Security, or other legal reasons. DDC helps make the on-site testing requirements easier to help you get accurate answers and move forward.
  • At-Home DNA (Non-Legal) Test
    Home testing is an easy and convenient way to confirm a relationship—no clinic visit required. Just order your test kit, follow the instructions, and ship your samples back to our lab and get answers within days of receipt at the lab.

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?

For security reasons, we do not send a copy of your results via email. Instead, a PDF report can be downloaded from your secure online account on our website. We immediately send a notification email to the address on file as soon as the online report is ready to view. If eligible to receive results, you may also request a hard copy of the report for an additional fee.

When will I receive my test results?

Depending on your desired test, you may be able to receive results in as little as 2–3 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.
