There are a lot of questions regarding what to know about DNA paternity testing, especially if you’re new to it. Paternity testing helps identify the true biological father of a child and provides clear evidence for legal issues or for people just seeking peace of mind. DDC answers several questions about DNA paternity testing without the father.
DNA Diagnostic Center’s (DDC) proprietary process allows a DNA paternity test without the father’s direct involvement. One way is to test one or both of the possible father’s parents or other first-degree relatives such as a brother, sister, or other known child. Non-standard samples from the possible father, such as a blood card if deceased, can also be used for testing. DDC specializes in using the most advanced methods to determine paternity for any scenario.

Paternity Testing Using a Grandparent or Other Relative
If a possible father isn’t available for testing, the best choice is to test one or both of his parents. Another option is to test the child’s DNA against the DNA of a sibling using our Sibling Test or Half-Sibling Test. We can also determine paternity using another close relative of the potential father, such as a brother or sister. All these tests, including the mother’s DNA, significantly optimize conclusiveness. To order a paternity test using the potential father’s relatives, contact our DNA relationship specialists to determine the proper test for you.
Paternity Testing for Court or Other Legal Purposes
A legally-binding chain-of-custody paternity test is the best choice if you require paternity testing for legal purposes. A chain-of-custody form that authorizes the test must be signed and processed for the court to recognize the validity of the results. A chain-of-custody paternity test with court-admissible results, cheek swabs, and necessary paperwork are sent directly to one of approximately 5,000 nationwide DNA collection facilities testing facilities authorized to provide services for DDC. We make the appointments for all participants. At that appointment, the identities of all individuals tested are confirmed, and samples are carefully handled to prevent tampering. Within 24 to 48 hours after samples have arrived at the lab, you receive online results that can be used as evidence for legal matters.
Paternity Testing Using Hair or Other Non-Standard Samples
Non-standard samples such as hair or a toothbrush from a potential father can be tested, although other items such as discarded ear swabs or used tissue are better. When non-standard samples are the only option, we work with individuals to determine the best sample for each situation. Once we receive your sample at our laboratory outside Cincinnati, Ohio, we will determine a profile from the possible father’s DNA. If the sample is sufficient, we compare this DNA profile to the DNA collected from the child’s cheek swabs to determine the probability of paternity. Results from this process are typically available within 5 to 10 business days but may take more or less time, depending on the quality of the sample.
How Accurate is a DNA Paternity Test?
DNA tests are powerful tools when determining paternity in divorce, custody, or child support cases. They help women identify biological and possible fathers and prove they are not biological fathers. The science has been rigorously tested and described in scientific journals. Results from our legal paternity tests are recognized in courts worldwide as proof of paternity.
How Many DNA Tests Are Done Each Year?
In 2006, the National Institutes of Health conducted a study showing that 300,000 paternity tests are performed yearly in the United States. Since then, that number has grown steadily, climbing to 400,000, according to the New York Times. The latter article also notes that men who question whether they are the biological father of the child they’re raising are, in fact, not the biological father about 30% of the time, which is a high percentage.
The AABB, an independent accreditation body for DNA testing, claims the number has surged to 500,000. Most of these tests are requested by child support agencies.
Paternity tests are useful for proving paternity in divorces and other legal cases. If the possible father isn’t available or willing to test, there are options for getting proof of paternity. If you are trying to determine paternity for legal matters, order a legal chain-of-custody test.

I want to do a dna test with my possible father but I don’t want to meet with him in person. Is it possible to send samples in separately?
Hi, Chelsea. Yes, absolutely. Call us at 800-681-7162 (M-F, 8 AM to 8 PM Eastern).
My father had a some at 17-18 years old. The child mother died at birth. He never knew the child but when my brother did a DNA on ancestry.com a family reached out. They are listed as 4th cousin. They dates and stories match of what my father told me but we want to do a more detailed analysis. Will it be possible with my brother DNA and this man who would be our nephew?
Hi, Terri. Is your father still alive and would he be willing to test. That would be your best option. Otherwise, you could do an avuncular (uncle) test.
Hi if the possible father sister wants to get her dna tested against my son’s how would we go about doing so ?
Hi, Lady! Just give one of our experts a call and they’ll be happy to arrange for an avuncular (aunt/uncle) test. That number is 800-681-7162 (M-F, 8 am to 8 pm Eastern).
I think my friend swabbed the father twice and pretend it was the child’s DNA .will she get positive results from this ? Will the results show He is the father?
Hi, Kathy. The lab would detect that both sets of swabs contain DNA for the same person and suspend testing without issuing results. The lab would then request fresh samples.
DDC March 4, 2020 I need further information on if DNA testing can be done with high noted results on a possible aunt/ niece pair. Please let me know as soon as possible please.
Hi, Kim. We do perform avuncular (aunt/uncle) relationship testing such as you describe. To optimize conclusive results, we highly recommend that the mother of the child also participate in testing. Please reach out to one of our case specialists directly for more information: 1-800-681-7162 (M-F, 8 am to 8 pm Eastern).
My son was arrested and is doing 50 years. It gas been five years and a young lady has told me her son could be my sons child. Getting a DNA test using my sons DNA is not an option right now but if this is my grandson I have missed so much time already, but if it is not I dont want to get involved emotionally.
Hi, Dee. Are you asking if you can do a DNA test to see if you are biologically related to the child? The answer is yes, as long as you have the mother’s consent. In fact, it’s best if she contributes her DNA to the test as well. You can learn more at the link below and/or call us directly at 800-681-7162 (M-F, 8 am to 8 pm Eastern): https://tests.dnacenter.com/relationship-testing/grandparent/
I had my father complete the Ancestry DNA Kit, in hopes of it helping us to figure out who his biological father is or was. He results matched him with a man, and it labels it as him as 1st – 2nd cousin. However the two other matches he has in that same category are a half brother and a half sister. Our thoughts are that this man is also a half-brother, but his father has passed away. Is there a way to find out for sure if they had the same father?
Hi, Stephanie. To clarify, whose father has passed away? And are you trying to figure out if the half-brother and half-sister and your father have the same biological father?
Kia ora my name is Tui I am 55 year old. My mother has passed away and my mum’s sister is married to my uncle whose brother claimed to be my biological father he asked me for a DNA five years ago and I ran out of time because he died last Xmas I want to find out truth so my cuz has offered to do DNA test with me but checking here looks like be better to ask his two brothers that are still alive also I don’t want to upset my mum’s sister who married his brother. What can I do. Also there is Maori land involved. He didn’t leave a will so if I can prove geaneology for my children mokos ect as he had no other children. I just want to know if he is my dad. Yours sincerely Tui
Hi, Tui. You’re right that the alleged father’s two brothers are a better option for you. Please contact us to get the discussion started on your best options: [email protected].
I just learned I have a half sister and a half brother but they have different mothers but we share the same father . I have a full blooded brother . What is the best option to verify if the halfs really are my dads children?
Hi, Margaret, if the alleged half-sibs are willing to test, you can do a half-sibling vs. unrelated test with the half sister. Your full-blooded brother can do male-lineage Y chromosome testing with the half-brother to see if they share the same Y chromosome from your father. I suggest you contact our experts for a free consultation to determine what might be best for you: 800-929-0847 (M-F, 8 AM to 8 PM Eastern).
My daughter had a dna test with the brother of the alleged father, how can i find out how to read the results?
Hi, Angie. You should call the lab where you tested for assistance.
My mother is deceased, and the person listed on my birth certificate as my father is probably deceased, also. I only have his name. There is no one I can turn to in order to find out where he was from, or when he was born. I am 76 yrs. old, and I would like to know if I have any siblings or other relatives. What can I do?
Hi, Miriam. You may want to try uploading your DNA to an ancestry-type DNA company that allows its users to share data. There may be relatives you don’t know about who have done the same!
The father of my baby passed away,so i did dna with grandfather.is it good
Hi, Agnes. Results are only valid if a grandparent test was done. The grandfather can’t “substitute” for the deceased father, since they only shared 50% of their DNA and not 100%.
