What do my paternity test results mean?

What Do My Results Mean?

The precise language used in your paternity report is very important but, because it’s also very technical, it can sometimes be hard to understand. The report language is familiar to scientists, lawyers, and judges. To help with understanding your results, we’ve also shown you how they might say it on TV, instead of in a courtroom.

Your Report

Each paternity test report shows the following information:
  • Conclusion
  • Combined Paternity Index (CPI)
  • Probability of Paternity
  • Data table of DNA markers (or genetic systems)
The Conclusion states whether the possible father is EXCLUDED or is NOT EXCLUDED as the biological father (see explanations below). The data table lists the different DNA markers (or “genetic systems”) examined by scientists to create the CPI and Probability of Paternity.

Your Result

If the Conclusion reads, “is EXCLUDED as the biological father,” this means that he is NOT the father because the data in the table do not support a paternity relationship. When a possible father is EXCLUDED as the biological father, the Combined Paternity Index (CPI) is 0 and the Probability of Paternity is 0%. What Do My Results Mean? | DNAtesting.com If the Conclusion reads, “is NOT EXCLUDED as the biological father,” this means that he is most likely to be the father because the data in the table strongly support a paternity relationship. When a possible father is NOT EXCLUDED, the Combined Paternity Index (CPI) is 100 (or larger) and the Probability of Paternity is typically 99.99% (or higher). What Do My Results Mean? | DNAtesting.com

Why do TV personalities say “you are the father” while scientists say you are “not excluded as the biological father”?

Scientists use precise language, whereas TV personalities generalize for dramatic effect. DNA paternity testing uses powerful statistics to create a probability of paternity, and the highest probability possible is 99.99% (not 100%). Saying, “You ARE the father,” implies a 100% probability of paternity, which is technically incorrect.  

So, just how powerful is a 99.99% probability of paternity?

A 99.99% probability of paternity is so powerful, that it’s routinely accepted as evidence in favor of paternity by genetic scientists, courtroom judges, and even the U.S. State Department. Although the scientific language is more technical than how they say it on TV, the bottom line is the same: a DNA paternity test probability of 99.99% is strong enough for a judge to confidently allow (or deny) child support, immigration, or even conviction in a criminal case. It’s also why a TV host feels confident enough to say, “You … ARE the father.”

      Thank you for your question. It is important to witness the collection of the samples when doing an at-home test. Were you able to be there when the samples were collected? Have in mind, mistakes can be made both unintentionally and intentionally. Our lab tests the relationship between the samples we receive, in no way can we verify a sample labeled “John Doe” actually came from John Doe. This is why witnessing is crucial to ensure accurate samples are received. I hope this helps answer your question. If you have any more questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

    Hello. I did a dna test with someone that is my siblings uncle. The results showed index: 2.4 an probability: 70%. Does that show a direct relation between me an that person? It was an uncle/niece test that we did. Thank you

    • Identigene says

      Hi Rhonda,
      Thank you for your question. Anything under a 99% or over 0% is considered an inconclusive result. This means no concrete result was reached. Did your biological mother or any other first degree relatives test? Typically in an avuncular test, inconclusive results will happen because there was not enough DNA or other participants to help reach a solid “yes” or “no” answer. I hope this information helps. Please call us for any more questions regarding your test and results. You can reach us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

  2. crystal25 says

    i have a question if you do a paternity test and the result was 99.38% and they said he is not excluded unless there is another party to be tested….what does that mean?

    • Identigene says

      Hi Crystal25,
      Thank you for your question. Typically, the statement refers to testing another possible alleged father, usually a first degree relative to the alleged father already tested. Was the biological mother included in the test? Have in mind, including the mother can strengthen results as well. If you have any more questions, please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

  3. wayne says

    Hi I have had a DNA test done and they said I am the Adjudicated father what does that mean? And I found out that my cousin had sex with the mother multiple times right before she became pregnant does this mean because we have the same blood line that he could be the father and if so how do I get the court to find out? He has another child so his DNA is already in the system would that help?

    • Identigene says

      Hi Wayne,
      Did you test with IDENTIGENE? If not, you may want to consult with the company you tested through for more specific answers to your results. ON behalf of IDENTIGENE, we can inform you that cousins have significantly different DNA, even brothers with the same parents can be tested with enough differences in DNA to obtain results. We recommend testing any two individuals in question for paternity if they are related. I hope this information helps. To set up or order a test, please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. You can also find our kit at your local CVS, Walmart and Rite-Aid locations. Thank you for your comment!

  4. nicole says

    Have 6year old and 1 year old different DNA strengths CPI one is 35,000,000 to 1 and other is 25,000,000 to 1 does age play a part in strength?

    • Identigene says

      Hi Nicole,
      Thank you for your question! The CPI statistic is a unique number generated between two people and their DNA. The CPI and the percentage of probability will match up. For example, if a person is excluded from paternity, the percentage will be 0% and the CPI will also be 0. When a person is considered the biological father, the percentage will be over 99% and the CPI will read as a number over 100. In a way, the CPI is a different way to report the percentage of probability. The strength can more easily be read in the percentage following the result statement.
      I hope this information helps. If you have any more questions, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

  5. Ike says

    I did one on myself for for my son its been 4 days and i haven’t receive the results back. should i be worried

    • Identigene says

      Hi Ike,
      Has it been four days since you sent the samples? If so, have in mind the mailing frame is 5-7 days (if using our envelope) until it arrives in our lab. If you provided an email address, you will receive a notification to let you know testing has begun. It will take 2 full business days for testing AFTER samples arrive. I hope this information helps. If you have any more questions, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. You can also check the status of your case by logging in online. Thank you for your comment!

  6. salll says

    I bought an at home kit from the drug store but do I still have to create an online account and pay the lab fee there?

    • Identigene says

      Hi Salll,
      In order to get results and get testing started, you will need to pay the additional $89 lab fee. Online registration and payment is a fairly new feature now available to you. However, we are more than happy to assist you set up your account and take the payment over the phone as well. You can reach us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET.

    • Identigene says

      Hi Joe,
      Thank you for your comment! If there is any possibility of a first degree relative, such as a father or brother, we highly recommend having them test as well. Please call us at 1-888-404-GENE Monday-Friday 9AM-6PM ET for any more questions or concerns! Thank you.

  8. octavia says

    My daughter did a dna test against tge guy I thought was her father. It came back 5% that he is the father. Meaning 94% he is not. What does this mean? How is this possible

    • Identigene says

      Hi Octavia,
      Based on the results, it sounds like the alleged father was excluded from paternity. Were you able to witness the collection of the DNA samples as well as the sending off of the samples? Have in mind that mistakes can be made intentionally and unintentionally. It is important to witness the samples being collected as well as sent off in order to ensure the correct samples were received. We cannot verify a sample labeled “John Doe” is in fact from John Doe. If you have a question or concern, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

  9. says

    I would like to know if my brother and I take this DNA test will this verify if we are full brother and sister or half brother and sister? Our mother recently passed and the father is refusing to take the test so I was told since he is the son of this fella and first born, it would be another way of getting results. Will I get a true and accurate result this way? I do not think I could get a court order after all these years and it would probably be costly too. Please advise. Thank you CP

    • Identigene says

      Hi Cherlyn,
      We do offer a test for siblings, however, it is not the same kit as the paternity test found in super centers. In order to get that set up, we recommend calling our friendly client support team. We do also recommend to have the biological mother tested in order to increase the chances for a conclusive result. The sibling test is $399 and can include up to 5 people, usually first degree relatives. For more information please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

  10. Ella says

    I did a paternity test with my estranged husband. I have no memory of having intercourse with him near the time of my son’s conception. My son looks exactly like the man I was seeing at the time. The DNA test said that my estranged husband is the father, but the CPI is only 97.83. Also, my husband and I match on 14 points of the test. What does this mean?

    • Identigene says

      Hi Ella,
      Thank you for your comment! While looks are important, it is not accurate to base relationships solely from visual traits. Were you able to witness the collection and sending of the samples? Have in mind that mistakes can be made both intentionally and unintentionally. With your result being a 97.83%, it is considered an inconclusive result. Was the biological mother included in the test? If not, we recommend including the mother because she can help strengthen the result of the test. Is the other potential father a relative of your estranged husband? If so, this may be a reason to have both of them tested.
      Human DNA is very similar, for this reason it is very common to see some matches with many others, not just your husband.
      If you have any more questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

      • Priscilla says

        I did a paternity test on my husband and his daughter but the biological mother was not inculded because she does not know. But if the test comes back saying 98.37% I know it means its inconclusive but does it mean there is more of a chance that he is than that he isnt the father. We did it this way cause through court its more expensive?

        • Identigene says

          Hi Priscilla,
          Thank you for your patience! You are correct, with a 98.37% it is considered an inconclusive result. Typically this will happen because the mother did not participate. However, your result is leaning towards him being considered the father. The only way to conclude this for certain (or any result) is to include the mother or test anyone else that may be related to the alleged father if they may be a potential candidate for paternity as well. I hope this information helps, and please call us if the mother’s sample can be sent in. That is the easiest and best chance to obtain a conclusive result. You can reach us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you.

  11. Sarah says

    I seen on server websites that you all have giving wrong results or they have taking a test twice and gotten 2 different results. . My boyfriend took one without me knowing && it said he is not the father && I kno i wasn’t with anyone else. He said maybe he did it wrong cause he feels our lil girl is his

    • Identigene says

      Hi Sarah,
      Thank you for your comment. There have been cases where people do in fact take two tests and receive two different results. Have in mind that paternity fraud is real, and does happen. Mistakes can be made intentionally and unintentionally. You can visit this page, which will explain receiving different results from two labs: https://dnatesting.com/i-got-different-results-from-a-different-lab-how-is-that-possible/

  12. briane says

    my boyfriends mother did a test for him. it came back cri 0.0385 it says the probability of relatedness is 3.7% and the likelihood the alleged relative is not the biological relative is 26 to 1. this means they are not related right? because I still have the babies mother trying to tell me hes the dad

    • Identigene says

      Hi Briane,
      Based on the numbers you have given me, a 3.7% is considered an inconclusive result. This means that a solid “yes” or “no” could not be reported. Is there a possibility of another first degree relative being an alleged father? Was the mother included in the test? We highly recommend having the biological mother tested in order to increase the chance of a conclusive result. If you have any more questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

  13. Tara says

    My son had sex with this girl and then 2-3 days later had sex with another guy (unprotected) now she has a child and we dont know which guy is the father. Can these DNA test tell which one is the father, and once you receive the results how do you read them. I have been looking online and I cant figure it out :( Thanks

    • Identigene says

      Hi Tara,
      Has the baby been born? If so, we can definitely do a paternity test which you can get from your local Walmart, Rite-Aid, CVS or independent drugstores. When you receive results for the test, we report a “conclusion statement” which will give you the result or whether the father is considered the father (not excluded) or is not the father (excluded). We do also offer pre-natal DNA testing, however it is a more intensive process and would need to be cleared by the doctor. If you have any more questions about either one of these tests or reading results, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

  14. aalysha says

    Hi yesterday tested me, my baby, and a possible father and sent it in today. I made an account but I didn’t find out about the setup until after I sent it in will that mess up me getting the results.? Also there is another possible father of my child that I did not test will that mess up the results.

    • Identigene says

      Hi Aalysha,
      If you have sent in the order form and payment you will be fine. Whether you fill it out online or by mail will not affect your results delivery. You will still be able to log on and view your results if you provided a username and password on your order form. Is the other potential father related to the one you have sent in? If so we recommend testing both of them along with the mother. If not, you can always wait to see the outcome of your first alleged father test and you can always send in the second alleged father’s DNA within the first 30 days of testing and add him to the test. I hope this information helps. If you have any questions, please call us at 1-888-404=GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

  15. Tia says

    I had the alleged father and my child take the test. She took the test and I witnessed it and I put it in the envelope. I then flew to meet the alleged father so he could take the test. 4 days later the alleged father took the test and I witnessed it and I put it in the envelope. I then mailed it myself 2 days after that. My question is; can xraying the DNA already in the box from the airlines cause a negative result? Can keeping the DNA too long in the envelope cause a negative result?

    • Identigene says

      Hi Tia,
      Thank you for your question! We are glad to hear you witnessed the sample collections from all parties. This can help prevent mistakes whether intentional or unintentional. DNA will not change from exposure to radiation from x-rays, so your samples are fine. DNA is also good for up to 6 months after the samples have been collected. I hope this helps answer your question. If you have any more questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

  16. Catherine says

    My boyfriend used one of your DNA test on my daughter without me knowing. I know I have not been involved with anyone else. The results say that they match on several different markers, but it says it’s a 0 to 1 possibility that he is the father. How is that even possible? I’m pretty sure some of her genes come from me also. How would it change if the mother is added to the equation?

    • Identigene says

      Hi Catherine,
      Thank you for your question. In this case, we recommend the collection of the samples is witnessed to ensure the correct samples were sent in to our lab. Know mistakes can be made both intentional and unintentional. We cannot ensure a sample labeled “John Doe” is in fact John Doe’s DNA. This is why witnessing collections is important when there is any doubt of result outcome. Your child does get half the genes from each parent. This is why including the mother is always recommended, but never required. (unless the case requires her to obtain a conclusive result) With your result, you achieved a conclusive result, which means including the mother was not necessary to obtain a solid “yes” or “no” answer. If you have any more questions, please call us at 1-888-404-GENE, Monday -Friday 9AM-6PM ET. Thank you for your comment!

  17. aalysha says

    No they are not related. And I don’t know if I provided a username but I know I provided a password the username is my email address

    • Identigene says

      Hi Aalysha,
      Correct, the email address (if provided) would be your username. Have in mind you can send in samples for a second alleged father after the first one is tested. You have 30 days to add participants to an existing case. Thank you for your comment!

  18. Justin says

    I have a weird question…I heard that someone supposedly had a baby with their Uncle. Now what I want to know is if I were to make that person take a DNA test if you would be able to tell that they are related?

    • Identigene says

      Hi Justin,
      I am having some trouble understanding which relationship you would like to test. The one between the child’s mother and her uncle or the child and the alleged father. Whichever one it is, we do have tests available. Depending how many people are available for testing, we can suggest a test for you to take and order. In order to better help your situation, please give us a call at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. We are more than happy to take your call and give you the best option for your case! Thank you for your comment and patience.

  19. Robyn says

    Hi. So back in 1988 my mother had paternity testing done on a couple men to determine my father. There was a ton of scandal and heartbreak surrounding this. I am now in my 30s and can continue not knowing. So i have begun the process all over thru identigene… my question is how do i find out who all was originally tested when the state did it and how can i get it f one again quickly ? My mother swears only 5men were tested and now one of the men says there are more than that… please help me identigene? There were only 7markers tested and the lab back then i researched and they have lost so many lawsuits due to false reports its sickening…

  20. cath says

    I had a DNA sibling test done on my daughter’s to try and see if they are full sisters or half. I included a sample from me too. The results came back at 89% and a conclusion that this would mean they are full sisters. I was under the impression that as my sample was included the percentage should have been higher? Thanks

    • Identigene says

      Hi Cath,
      Thank you for your comment! With an 89% result, it is considered an inconclusive. More than likely, this means that there was not enough DNA to give a stronger result. Are there any other first degree relatives willing to test? We highly recommend including more first degree relatives in order to obtain a conclusive result. Please call our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-6PM ET so we may assist you and talk about more specific options. Thank you for your patience!

  21. Rayon says

    I did this test. But I wasn’t the one that sent it off. So I want to know if your test consider race. In terms of mix children. My son has an Asian mother and I am black. I don’t know if she switched the samples. So does the test considers race into it?

    • Identigene says

      Hi Rayon,
      It is important to mark the envelopes correctly. One of the requirements is ethnicity for each participant. If you are unsure of a possible switch within samples, we recommend letting our lab know by calling our friendly client support at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

  22. Tabitha says

    My ex did a DNA test for our daughter but the results came back saying he was not the father. I was not there to witness him taking the test nor did they ask me to take the test. And I didn’t sleep with anybody else could the test results be 100%?

    • Identigene says

      Hi Tabitha,
      Thank you for your patience! We do highly recommend to witness the collection and sending of the samples to our lab. We also do not require the biological mother to test, it is however highly recommended. If there is any reason to believe the samples may have been tampered with, we highly recommend doing a court-admissible test. Mistakes can be made both intentionally or unintentionally, this is why it is important to have the collection witnessed. Our lab cannot verify if a sample labeled “John Doe” did in fact come from John Doe. If you continue having any questions or concerns, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

    • Identigene says

      Hi Lanika,
      With a result of 99.99% probability, this means the tested alleged father is considered to be the biological father. This is the highest probability a DNA test can result in. If you have any more questions on your results, please call us at 1-888-404-GENE, Monday-Friday 9AM-6PM ET. Thank you for your comment!

  23. Christina says

    I was wondering. . . A home dna paternity test was done. The mother did not provide a sample. The child and posible father did, but The mother was the one who mailed it. Now we saw the sample go into the envelope. . . But is it possible the mom could of gotten another test behind our back, submitted her sample in place of the father? I ask because the child shows the x int the bottom box….except the posible father shows x/y ? Was the father’s sample checked to see if it was from a male or female?

    • Identigene says

      Hi Christina,
      Thank you for your patience! Our lab does test for gender. If the alleged father sample is tested to be a female sample, our lab will request a recollection to make sure all correct samples are collected. We highly recommend having the collection of the DNA witnessed as well as when the samples are sent off. To prevent mistakes, whether intentional or unintentional, we recommend having a court-admissible test done. Court-admissible tests require a disinterested third party to witness and administer the test. I hope this information helps.
