No, you do not need the mother’s DNA, however it may be helpful in some cases to eliminate her DNA from the child. This occurs in about 2% of grandparent cases. We do not charge for the mother’s DNA sample when it is submitted at the time of the testing. In the event her DNA is suggested, it can be added after the testing results if desired.

If both grandparents are available to test, you may also want to consider that option, as the testing results are no different than a paternity test using the suspected biological father.

When both grandparents, or the mother,is not available our testing laboratory will automatically adjust the testing to account for one grandparent and one child.

If you are seeking answers for personal information only, then the test can be done discreetly and privately between grandparent(s) and grandchild(ren) without any other person knowing.

If you are needing a legal DNA test then the custodial parent or legal guardian will need to give written consent.

Yes! Only the person who orders the test has access to the information.  We never discuss results with anyone else to ensure your privacy.

Yes! Alternate samples are very common to use when you want to have the testing run in a very discreet way. To learn more about Alternative Samples click HERE.

The testing is based on the genetic profiles we obtain from the DNA samples sent for examination. The results we deliver are based on the testing process and the probability we list 100% accurate as delivered. A probability of relationship greater that 90.9% is considered conclusive proof of the relationship.

The  Since the grandparents DNA profiles contain all the key components of which the alleged father and the grandchild’s DNA is made up of, the strength of the probability may be increased if both Grandparents are available.  Our grandparent DNA test can be as strong of a result as a paternity test.

Many grandparents order this test because they are concerned that they might not be the actual biological grandparents of a child or children. They are rightfully concerned, and only want to know the truth. Being a grandparent requires both emotional and financial support for many years, and if there is a question about the paternity of a grandchild, the grandparents have a right to know with certainty that they are related. Aside from peace of mind, there may also be legal reasons for wanting to confirm a biological relationship if the suspected father of the children is not available.

Reasons to confirm paternity include:

  • Health concerns
  • Death of potential father
  • Custody issues
  • Heritage and inheritance concerns
  • Questionable paternity of child
  • Peace of mind

Yes. If you are needing a DNA test for death benefits, then it will need to be the legal DNA test. If the grandparents are still living and willing to do the DNA test, they would be great candidates if the father is deceased.

If the child at question is a male, and the grandfather is available, we suggest you test male to male. When testing 2 males for a relationship DNA test, they have the extra advantage of including Y chromosome testing, if it is necessary. Y chromosomes are an exact match down the male lineage.

If the grandfather is not available, the lab makes the necessary adjustments to test a grandmother and possible grandson.

If the child at question is a female, a DNA test can be done with the grandmother or a DNA test with the grandfather as either will be sufficient in almost all cases.

Unfortunately not.  The genetic tests that are performed for grandparent DNA tests are only screened for the sole purpose to find genetic matches in the other individual testing against.
