How DDC DNA Diagnostics Center Works

DDC DNA Diagnostics Center offers a slew of different DNA tests, from paternity tests to tests taken for immigration purposes.

There are two ways to go about pretty much any of the available tests:

  • Legal – In situations where your DNA test results incur some legal ramifications, a DDC appointment coordinator will arrange for you to provide your DNA sample at the most convenient location near you. Adoption or confirmation for in-vitro fertilization are good examples.

The professional collector will then complete the paperwork, compile identification, and send your package to DDC DNA Diagnostics Center for testing.

These legal test results are a viable proof of claims in front of immigration agencies and courts.

  • Non-legal – If you have no intention of using DNA results in court and just want them for your personal peace of mind, the non-legal route is the right choice for you. This option allows you to collect the sample yourself, at home, and simply send it for testing.

DDC encourages people to take the legal route, though, since it has noted an ever-present trend of customers taking the non-legal test and then returning for the legal variation once something “comes up.” The waiting period depends on the type of test you’ve ordered. Once the results are done, though, you can inspect them online immediately.

Why Choose DDC DNA Diagnostics Center

DDC is a true asset for anybody in need of high-quality and reliable DNA testing. It doesn’t matter what kind of genetic examination you require, DDC will have it in its portfolio.

Here are some of the service’s highlights:

  • Largest company of its sort
  • Excellent array of tests
  • Legal and non-legal testing options
  • Dr. Michael Baird, the world’s leading DNA expert
  • Most accredited lab in the world
  • Perfect results with 16 inspections
  • Accuracy 100% guaranteed
  • Advanced robotics technology
  • Every test is done twice
  • Same-day paternity tests
  • Ph.D. result revision for every test ordered
  • Strict confidentiality measures
  • Affordable prices
  • Flexible payment possibilities
  • Knowledgeable user support
  • Free pre-test consultation


This is where DDC really gets to shine. Its tests are not overly ancestry-oriented, like with some other companies we reviewed. DDC has an ancestry test featured, but it focuses more on your everyday DNA needs, to put it colloquially.

DDC will first help you with your “modern” preoccupations like adoption, immigration, child support, taxes, and court orders and “dig” through the past, looking for your pre-historic ancestors once all the burning questions receive satisfying answers.

Having said that, these are the tests in its portfolio:

Paternity tests 

These tests compare the assumed father’s DNA with that of the child to determine whether they match or not. If a certified professional is performing it, this test is the ultimate proof of a biological relationship with a 100% accuracy guarantee.

DDC DNA offers three variations:

  • Paternity test with legal results (499$) – It requires all parties involved having their DNA sample collected at a facility with proper certifications (health department, a medical office, hospital…).
testing-DDC DNA Diagnostics Center paternity

The samples will be stored in a tamper-proof packaging and sent to Fairfield, Ohio, where DDC conducts its tests. The test uses cheek swabs, a completely painless and time-saving method.

As soon as the results are in, the document will be mailed to you and you can use it in court or wherever your legal needs require you to.

  • At-home paternity test (starts at 199$) – This test is the best choice if you just want quick information and have no legal expectations of it. The results of this test are not admissible in court.

DDC will dispatch a sample collection kit the same day you order the test. The kit also uses cheek swabs. After sample collection, just send it back via a pre-paid express envelope.

The results will be ready for you online within 24 hours of receiving the sample. You will get an e-mail notification as well.

  • Non-invasive prenatal paternity test (payment plans available) – The test uses solely the blood of the mother, so there are no potential dangers for the baby.

The developing fetus starts “emitting” its cells into the mother’s bloodstream as early as 8 weeks into the pregnancy. DDC has developed a proprietary method of collecting those fetus cells, developing their DNA profile, and matching them against the presumed father’s DNA.

This state-of-the-art test combines the latest trends in DNA SNP technology for the safest possible collection, preservation, and analysis of the baby’s DNA. The results are usually back in 3 work days. The side-benefit of this test is the ability to determine the baby’s gender.

Relationship tests

Being the most sought after, the paternity test has been segmented out into a separate test group, the family relationship tests.

They include:

  • Maternity test (starts at 295$) – Similar to the paternity test, this test compares the child’s DNA with the presumed biological mother.

The father’s involvement is optional, although highly encouraged since it can exclude the father’s half of the DNA from further testing. Testing the father doesn’t raise the fees required for the test.

As with paternity testing, both legal and non-legal variations are available.

  • Grandparent test (starts at 395$) – It’s used for establishing the paternal DNA line between the child and the grandparents. Thus, the grandparents tested must come from the father’s side. Mothers are encouraged to participate as well since it saves time on additional analysis.DDC can also lend a helping hand if there’s just one grandparent left. If this is your case, you can call the company and elaborate on the specifics. This test is primarily used for inheritance claims, social security benefits, and immigration cases. Both legal and non-legal versions are available.
  • Sibling test (starts at 395$) – It is used when potential siblings want to determine their father-line connection and the father’s DNA is unavailable. In the case of an absent father, the next step would be testing the grandparents. If they’re unavailable as well, the sibling test is the only way to go about it.The sibling test explores 35 autosomal markers looking for a match. This ensures a thorough analysis and precise results.
  • Aunt/Uncle test (no price listed) – The “avuncular” test uncovers the child’s potential biological relation with the father’s sibling. The test is used when the father’s DNA is unavailable and the only relative left is the father’s sibling (sister or brother). An uncle/aunt will share 25% of their genetic material with their nephew/niece. This is an alternative way of determining paternity.
  • Family reconstruction (no price listed) – This test is used to determine a biological relationship through the father’s relatives when the father is not available. The test can only be successfully performed with 3 or more paternal relatives. If there are only one or two, the participation of the mother is required.
  • Male lineage (no price listed) – A paternal or Y-test is used to establish a biological relation to a distant paternal relative.

Legal and non-legal options both exist and the results are usually available in 2-3 weeks.

  • Female lineage (no price listed) – Also known as the mitochondrial test (short mtDNA), it determines maternal blood relationships.

The options and waiting period are the same as with the paternal lineage test.

  • Twin Zygosity test (no price listed) – This test is used to determine whether twins are identical or fraternal.
twins-test DDC DNA Diagnostics Center

The term “zygosity” simply means “the level of similarity.”

This test is a crucial tool if one of the twins needs an emergency organ transplant, as an identical twin is a perfect donor.

  • Native American DNA test (no price listed) – The test is customizable to fit every tribe’s needs and the turnaround times are usually pretty quick.
  • Immigration DNA – The test will provide the proof you need to successfully conclude your immigration process.

DDC features a specialized immigration team, which has been dealing with immigration petitioners, embassies, agencies, and beneficiaries for over 20 years.

Specialized tests

DDC also offers DNA tests for US and Canadian immigration and incorporates 3 separate websites for ancestry, forensic, and animal DNA testing. Every single test DDC offers comes with free pre-test consultations, a Ph.D. review of the results, and a knowledgeable support team ready to answer any question you might have.

Every test is done twice to avoid any potential errors and miscalculations.

Privacy And Security

DDC takes the privacy and security of its clients very seriously. It follows a very strict privacy policy, which entails:

  • Never releasing information about your case to anybody without your explicit permission;
  • Always following your special instructions (if any) concerning communication with other parties regarding the test;
  • Never releasing results of the test over the phone.

  2. Julia Defreitas | June 6, 2020

    If you were contemplating the need to request the 3-day result turnaround, please do yourself a favor and ask for it just in case. Here’s what happened to us:
    For our situation, we decided to go with the non-invasive prenatal testing. We had already been scammed by another DNA testing company, so we thought “better safe than sorry” and purchased the VERY expensive but legally sound DDC test. My consultant was aware of the awful experience we had with the prior company and assured me we came to the right place for fast, accurate answers. On May 8th, potential father #1 went and left his sample at his local assigned facility, while myself and potential father #2 left samples at our local assigned facility on May 11th. After getting no confirmation email that all of our samples had arrived at the lab for over a week, I sent an email to the customer service department on May 15th asking if they could help find the problem. After receiving no reply for 5 days, I called the help line on May 20th to try and figure out what the hold up was. The woman who answered informed me that they had never received a sample at the lab for potential father #1. She told me to have him call and follow up with where his sample was. When he called a couple hours later that same day, they told him his sample “might have been sent to the wrong department”, and placed him on a 20 minute hold while they tried to figure it out. Eventually they got back on the line and asked him to just schedule a new sample collection appointment instead for the following day, May 21st, and that they would have it overnighted to the lab. On May 26th, I finally received confirmation that his sample had arrived at the lab due to their closure May 22nd thru 25th for Memorial Day (which made the attempt at overnighting the sample to speed up the process a waste) and that results would be available online at 6pm on June 4th. I again sent a detailed email to the customer service department, as well as the woman who had sent me my appointment confirmation email because she was the only other email address I had for the DDC, the night of May 26th. I explained everything that had happened, clearly stating that their losing of the sample was not something we could control, and that we needed results before May 29th because potential father #2 would not be physically available after that morning, and potential father #1 was not going to be within cell service June 2nd through June 28th. Kimberly in scheduling was very helpful in reaching out to customer service to try and get them to contact me, but when they did a couple hours later I was basically just told “Sorry that happened, we asked the lab to monitor your case but that’s all we can do”. I sent another email June 2nd requesting that someone in customer service reach out to me to discuss how they could make this situation better, and still nothing. I ended up receiving results June 3rd, almost 4 weeks after the first sample was taken, over 2 weeks after our initial promised result date, and unfortunately we didn’t expect it to take so long. While I trust that these results are credible, I’m so upset I spent that much money to use a very professional, well liked company and was shown that they could not live up to the timing standards they promised or take responsibility and offer to help a situation they messed up. I would hate for this to happen to anyone else because it has hurt a big part of the excitement I should be sharing with my child’s father, who will not have service until the end of June because he is underway for the Navy, which is something that I’ll never get back. I will continue to reach out to them until someone cares to explain what happened and compensate me in some way for their mistakes. If I was giving this place a review just based on the experience, it’s no more than 1 star.

  3. Tamika Senior | January 6, 2020

    I was adopted as a little girl and never knew anything about my real parent except that they are Native Americans. My adopted parents supported my decision to find out where I came from so I did the family relationship testing to try and find out if I’m related to someone from one of the tribes. I still haven’t reached to anyone even though I know who to talk. It was only important for me to know where I come from.

  4. Lara Woolley | December 15, 2019

    I hired DDC for the purpose of a paternity test my boyfriend refused to take claiming that the child is not his. I was thrilled with the level of professionalism and felt better knowing it was done by experts in a proper institution. Never doubted the results for a second.

  5. Eden | December 3, 2019

    I am very satisfied with the customer service i got. My sales rep Michelle Sexton was very professional and helped me out alot. Rating her customer service at 100% and beyond thank you

  6. Parker Donovan | November 9, 2019

    I’ve chosen this company because it been in the business longer than anyone else on the market. It is reliable and its reputation speaks for itself. I honestly wouldn’t trust anyone else to handles this type of work except for them!

  7. Nabi | October 22, 2019

    One of the most corrupted companies I have ever seen. They are very happily taking your money in a minute, promise you to do the job within couple of days and then will totally forget about you. You will be calling them and they will not even answer your call. I would definitely not recommend anyone to do the DNA test with these guys.

    • KIMYONA LATOYA RAY | October 20, 2020

      I concur!!!!!!! This business is a scam scam scam scam scam. Do not pay for any prenatal paternity testing! They will take your money and take your money and take your money and…..you will have no results!

  8. tori maricelli | September 10, 2019

    I talked to service rep Michelle Sexton and she was great and helped me through the whole process. I did not do a conventional test on one of the subjects. DNA was collected off an item that belonged to one of the parties. All of customer service agents were great and showed me compassion and caring. All went well except one little hiccup which was that one of the lab techs gave me the wrong day on when results would be in. A manager got in touch with me and explained the mix up and apologized profusely. I paid extra to have the test kit sent over night and they paid for me to ship back over night which was fantastic. I had to pay a little extra for testing due to the one sample being taken from an item other than cheek swab. All in all I was satisfied and would recommend and although I hope I NEVER have to do this again, I would use this lab. I would also recommend shipping and receiving OVER NIGHT mail. It was well worth the money and peace of mind we now have. God bless

  9. Lori Braun | April 16, 2019

    This place is horrible. Unprofessional at best. Toying with peoples lives… their emotional state is just down right unacceptable. They promise results and do not follow through. Not once but twice. We still do not have our results as of today. They dont answer the phone, let alone return calls. Leave you on hold for hours. I should have read the reviews first, but seeing how this is supposed to be the best, I didn’t. And my/our families are paying for it. I will be contacting the BBB as well. I want what they have done on record. I also posted a review on their site and it was deleted this morning. This place is a joke.

    • KIMYONA LATOYA RAY | October 20, 2020

      I concur! This business is a SCAM!!!

  10. Anna | March 31, 2019

    HORRIBLE service. Keep getting the run around on our test results. Paid for results in two days and its a week now and they keep making excuses as to why its not done. DO NOT USE this company!! They don’t even deserve one star. Their collector filled out everything and did the swabs and they are still giving us a hard time getting results. No one ever picks up the phone, on hold for hours then the system hangs up on you.

  11. Savannah Calhoun | January 18, 2019

    This is the worst experience! I decided to get a paternity test with a guy who can be my dad. We sent them off November 27. Two weeks later I had not received any email. I called and they said my samples were received and I would know my results the next day. They required a reswab. I sent the email requiring a new test. I did not receive it until I called after over a week. I finally received it and sent it back the 27th of December. I did not receive a email so I called and was told they hadn’t received them and to call USPS. After waiting on the phone with USPS for 2 hours I found out they received my samples the 28th. I called again and it was confirmed. Here I am on Friday with no results in sight. Hold time is so long!

    • KIMYONA LATOYA RAY | October 20, 2020

      Yep they gave me the run around from October 10th to October 20th and promised me a three day processing time and I still have not received results. Their emails are short and the whole business has a very unprofessional, sketchy vibe too it! Please do not do the prenatal paternity testing. I am trying to save everyone $1500.00.!!!!!!!

  12. Suki | October 4, 2018

    Worst company to deal with ever. Purchased the kit from Walgreens, and sent out the envelope to the facility. I got an email to get in touch with them, i did and they advised for a reswab. Two weeks have passed and i still have not received anything in the mail. I called and they said it usually takes from 3 to 4 weeks to get the new kit… 3 to 4 damn weeks to get a package in the united states. Most horrible company and a experience i have ever dealt with. I do not recommend this company to anyone.

  13. Latonya Waterman | May 5, 2018

    Excellent Service. My fiancee had concerns of whether his oldest daughter was his. We dad father-child and let’s just say I have four sons and now loving my two stepdaughters. Thanks DDC for your excellent services.

  14. Susy day | April 14, 2018

    My deceased ex husband had a woman say he was her daughters father for 37 years. The daughter had a test done using his and her blood test came back (0) not his. Both of my kids are relieved and his family just thought for sure was his daughter. Well not his thank you Jesus now maybe the daughter of the woman’s can finally find the real father after all of the years . Good luck your going to need it .

  15. Caro | March 28, 2018

    Horrible service. I wrote a review on their page and they deleted it. I paid for fast 2 day service and its been 1 week and still waiting on Results.

  16. Constance | March 22, 2018

    I live in NY and bought their paquet from Walgreens. Opened the paquet nothing inside. Called them then they explain that in NY DNA test have to be authorized by a doctor. They proposed to send a new kit to the person with whom I was going to do the test because the person lives in a different state. I paid for everything thing in advance (lab test and the new kits they were supposed to send). More than 3 weeks later, the person haven’t received anything. I called to make sure the name and address were good and if they can give me a tracking number. The person’s information were good but the company couldn’t give me any tracking number or something to prove to me that they sent the kits to him. Called back to cancel everything, they said they will give me back a refund, almost 2 weeks now still nothing.

  17. Richard Green | August 13, 2017

    I just did a paternity test, and it was all quick and as painless as possible.

  18. Keith Jordan | July 28, 2017

    The test went fine an all but me buying the test box myself was a hasle

  19. Wendy Michaels | May 23, 2017

    I just found an aunt I never knew I had! Thank you ddc!

  20. Ganesh Bhattacharyya | April 17, 2017

    I done the test for imigration and the wrong one. Have to do it again to give to court. Customer support was really nice and helped a lot.
