At a glance

  • Thanks to advances in scientific techniques, it’s possible to perform a paternity test without the biological mother’s DNA sample.
  • By collecting cheek (buccal) cells from the potential father and the child, the testing laboratory can analyze and compare DNA markers to determine which half of the child’s DNA is inherited from the potential father – with no need to collect a sample from the mother.
  • As the mother’s DNA sample is not required for a paternity test, her consent/permission is not needed to perform the test, provided the potential father has parental responsibility for the child being tested.
  • A mother can also refuse a paternity test. However, her permission is not needed to carry out the test provided her DNA is not being submitted for testing, and the potential father has parental responsibility.

What is a peace of mind paternity test?

A peace of mind paternity DNA test can prove paternity by analyzing DNA from the potential father and comparing it to the child’s DNA.

Every person inherits half of their DNA from each of their biological parents, so this comparison can help us to establish the probability of paternity.

An AlphaBiolabs peace of mind Paternity DNA Test looks at up to 45 DNA markers to identify which half of the baby’s DNA is inherited from the potential father.

When testing the biological father of the baby, both will share identical sections of DNA at each marker. When the tested man is not the biological father, this is not the case.

As the name implies, the results of a peace of mind paternity test are for your information only and are not admissible in court.

Can I do a paternity test without the mother’s DNA?

An AlphaBiolabs paternity DNA test is performed without the mother’s DNA. You will still receive a conclusive result.

This is because by collecting cheek (buccal) cells from the potential father and the child, we can analyze and compare DNA markers to determine which half of the child’s DNA is inherited from the potential father (if they are the biological father of the child).

As the mother’s DNA sample is not required for an AlphaBiolabs peace of mind paternity test, her consent/permission is not needed to perform the test, provided the potential father has parental responsibility for the child being tested (if the child is under 16-years-old).

Any person over the age of 16 must provide their own written consent (a signature) for their DNA samples to be tested.

Without the correct consent, AlphaBiolabs cannot perform a paternity DNA test.

Can a mother refuse a paternity test?

Yes, a mother can refuse a peace of mind paternity test and there are many reasons why a mom might do this.

They might be hesitant about the consequences if their partner is found not to be the child’s father, or they may be uncooperative because they simply do not want the father of the child to be involved in their upbringing.

Relationships may have broken down, the parents may have started new relationships, or mom may have identified another potential father figure for her child.

Whatever the circumstances, the fact remains that it is usually easy to identify a child’s biological mother, but only scientific DNA testing can confirm paternity and name an individual as the biological father.

Although a mother can refuse a peace of mind paternity test, the mother’s permission is not needed to carry out such a test, provided her DNA is not being submitted for testing and the potential father has parental responsibility for any child being tested.

Regardless of who is instructing the paternity test, written authority is needed from any person over the age of 16 whose samples are provided for DNA testing.

If testing a child under the age of 16 only parental consent is required. This consent must be provided on the child’s behalf by a person with parental responsibility.

      Hi Cherie. For a paternity test, we only need cheek swab samples from the child and the potential father. However, consent for a minor MUST be provided by an adult with parental responsibility as defined under the relevant State law.

    I have a friend who was not put on his son’s birth certificate, when him and the mother were together he was caring for the child and providing everything. Since they have separated and he is not on the birth certificate, the mother and her family, who have the child are refusing to allow him access to the child. Would my friend be considered a person with parental responsibility? He is trying to establish paternity so he can have visits with his child.

      Hi Chantel. Unfortunately, we are not able to offer you guidance on this matter, as it is a legal issue. We therefore suggest that your friend speaks to a family law attorney.
