DNA Paternity Test without mother

We are often asked whether a paternity test can be performed without mom’s DNA.

In this article, we explain what is required for a paternity test, including whether you need the mom’s DNA and whether the mom can refuse a paternity test.

It is important to remember that AlphaBiolabs cannot perform a peace of mind paternity DNA test without the written consent (signature) of anyone over the age of 16 whose DNA is being submitted for testing.

For a child under the age of 16, only parental consent is required to carry out the test. This consent must be given by a person with parental responsibility for the child.

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).

Do I need the mother’s consent for a paternity test?

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.
