How can I determine paternity without a paternity test?

Can you determine paternity without DNA testing for paternity?  Not positively. Paternity DNA testing is the only way to know for sure; however, there are tools that may help with providing insight to a possibility of paternity.

There are ways to estimate date of conception, which can be found all over the web. Identigene offers Blood Type Paternity Tests, and Eye Color Paternity tests. Keep in mind these are tools to assist in determining if the alleged father could possibly be the biological father. They cannot give definitive answers about paternity. Only Paternity DNA Tests can accomplish that.

EYE COLOR PATERNITY TEST

Eye color paternity test shows how eye color and inherited trait theory can be used to help determine paternity. This test is based on theories about genes and how they are inherited from biological parents. With this test you enter the Mothers, Alleged Fathers, and Child’s eye colors to determine if paternity is possible.

BLOOD TYPE PATERNITY TEST

Blood type paternity test can also help eliminate a potential father, or determine if paternity is probable. The Identigene blood type paternity test shows how ABO blood type and inherited trait theory can be used to assist with answering paternity questions.  With this test you enter blood types of Mother, Child, and Alleged Father to determine if paternity is possible.

PATERNITY DNA TESTING

These tests are helpful to determine if the alleged father could possibly be the biological father. Paternity DNA testing is the only way to get clear paternity results. Keep in mind also that with DNA technology continuously making leaps and bounds, Paternity DNA Testing has become more affordable than ever.

  1. Is there a way to determine paternity through a sibling? My father is deceased. There are 4 children. The question is if I have a different father than the rest of my siblings.

    • Hi Christine,
      Thank you for your interest in Identigene. As for your question, we can and do offer a sibling test, since everyone gets half of their DNA from the mother and the other from father. We can determine relationship of siblings to:

      • Full vs. Half
      • Full vs. unrelated
      • Half vs. unrelated

      It is always best to give us a call so that we can more effectively evaluate your situation before ordering a Sibling DNA Test.

      The Sibling DNA test runs $399, typically take 5 days to complete and we cannot guarantee conclusive results. The test results for siblings will fall into one of four categories: strongly supported (conclusive), somewhat supported, inconclusive or not supported. We do strongly recommend including a sample from the biological mother (both mothers when relevant) because there is a greater chance that the results will come back inconclusive without her. We can try to do the testing without her sample included whenever she is not available, but without her sample it will be highly likely that the results will be inconclusive.

      I hope this information helps. Feel free to give us a call 1-888-404-4363, Monday-Friday 9AM-8PM ET with any further questions you may have and we will be more than happy to help you!

  2. What other DNA material other than cheek swabbing can be used to determine paternity? Can DNA be obtain from the deceased father?

    • Hi Diane,

      Our lab can test a variety of DNA samples to determine paternity, however, they are considered non-standard samples if the DNA is not collected on our standard buccal swab. Non-standard samples cost an additional $400 per non-standard sample. You’ll want to contact our client support staff to talk to them about the samples that we can test. Their phone number is 1-888-404-4363.

  3. How can I prove paternity with out mother or child knowing they live out of state and I have not seen them for a very long time.

    • Dear Monte,
      If you are testing for paternity, we require the child and the alleged father’s DNA. If the child lives in another state, you can contact IDENTIGENE client support at 1-888-404-4363 and they can mail a kit to the mother’s address and to your address. Our added advice for your situation, it might be wise to consider upgrading to a legal collection so that the swabbing is witnessed by a third party (hired by IDENTIGENE) so that the testing is done properly and it eliminates any questions of participant dishonesty. Please let us know if we can help futher. Thank you for contacting IDENTIGENE.

  4. A russian girl got pregnant for an african friend of mine. He suspects her of cheating while they were dating and asked her several times but she keeps on denying it. Their baby is so cute, but looks very white.
    He really wants to know if the baby is his without a paternity test

    • Hello Barry,
      The only way to know for sure is to conduct a DNA paternity test. Eye color, skin color and blood type are all genetic traits that could help support his reasons for a paternity test. If he is interested in a DNA paternity test, he can purchase one from any major drugstore or online at http://www.dnatesting.com or walmart.com. Please feel free to pass along our client support number, 888-404-4363.

  5. I was wondering if you could give me some advise regarding paternity and do you think it is necessary to have son tested. The couple only met each other in April and baby was born at 31 weeks gestation in October. she was in hospital hardly a day and baby weighed 2.7kg and length was 57cm. the father and son has the same birth mark on the same leg and same spot but i have googled and they state that birthmarks are not hereditary. could you please give me some advise on this as she refuses DNA.

    • Hello Jessica,
      We can only recommend to take a DNA paternity test if someone questions paternity. You can purchase a DNA paternity test at local U.S. drugstores. We do not need the mother to test, only alleged father and child. Please let us know how else we can help. You can always call us at 888-404-GENE with more questions.
