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.

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.

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;

    I received my test results that I’ve been waiting months to get this morning the woman had told me my password was my phone number and I’ve been trying all day to get my report now every number says that y’all are closed so I can’t talk to anyone until Monday! Also I don’t know what happened but my security question is saying she put in the wrong city I was born CAN YOU PLEASE HELP ME NOW???

  2. Murphy | December 28, 2021

    I paid $1,300.00 ft or a DNA test that should have the baby’s gender included. Unfortunately, the baby’s gender was not detailed. I paid a substantial amount of money for a test to include information and it makes me question the accuracy of the test if you can’t tell me the gender of the child. Reading the document I noticed my results were available on 12/22 but they did not release them until 12/27, they were just sitting around on someone’s desk. They sent me the results 1 minute before they closed so I could not call and speak to anyone about it. I called the next day and a representative named Melody told me that they were not able to give me that information because I possibly calculated my gestational weeks incorrectly. Once I was transferred to a supervisor she tried to argue with me and told me she doesn’t have time to go in circles. This is the worst customer service and lab work I’ve ever experienced.

      I was wondering if the result of the test is correct? did you test again after giving birth?

  3. Tiffany Northern | October 26, 2021

    I reached out to many testing centers for a prenatal dna test. I ultimately decided to go with DDC. While waiting around for the test to arrive at the testing center I unfortunately had a miscarriage. I’ve reached out many times in regard to this matter and reimbursement on my deposit and haven’t gotten anywhere. I thought such a highly rated company would have better customer service.
