Legally Verified DNA Test

Price: $495
Testing: Alleged parent and child/children
Timeframe: within 7-10 working days of receipt of DNA samples

In a verified legal DNA test (which is not NATA accredited), adults participating in the test must have their samples collected by an independent third party such as a Doctor or a Nurse and follow what is called a Chain-of-custody collection procedure. This test can be used when people want reassurance that samples being submitted are indeed from the correct people. During the sample collection process identification must be presented and passport photos will also be submitted and this is all documented at sampling.


International Biosciences cannot unconditionally guarantee your results will be accepted in a court of law. Judges in family courts will always act in the best interests of the child or children. This means that although the results of a legal paternity test cannot be disputed, a judge can still refute the results of a test.

Science Behind The Test

Once we extract a 21 genetic marker profile from the sample of the alleged father and the child (or mother and child in the case of a legal maternity test), we compare the 2 profiles. If we see that all genetic markers on the profile of the alleged father and the child are identical and match at every point, we can confirm that the tested father is the biological father of the child. If genetic markers do not match, then the tested father is not the biological father of the child.

Legal Testing Sample Collection

Unlike a peace of mind test, where individuals are responsible for collecting their own samples, a legal test has a very different procedure in place. A neutral third party sampler will need to be appointed for the sample collection and GTL will send a legal sample collection kit directly to your chosen sampler. Your kit will contain:

  • 2 oral swabs per person
  •  Instructions
  •  Consent forms

Carrying out the test is very straightforward. The Court Approved DNA tests require that an independent witness, such as a GP or health professional, oversees the sample collection process and is able to verify photo ID and maintain chain of custody. The chain of custody is essentially a procedure used in legal scenarios where all samples must be collected in a certain way and the provenance of each sample collected documented. The consent forms need also be filled out and include personal details such as names, surnames, email addresses and provide signatures – consent forms need to be returned back to us along with the samples.

The sampler will be only person handling the swabs. Swab samples need to be collected from every test participant by rubbing the swabs inside the mouth for ten seconds.

The instructions inside the kit will explain the procedure to follow and any precautions required.


What is the cost of a legal test?

• What type of test do you need?
• How many people are taking part in the test?
• Do we need to send out additional kits?
• Where are the test participants based?
Note that any fees relating to sample collection are set by the sampler. Embassies or consulates will have their own samplers. Any fees for sample collection are not included in the cost of our test.

What is the difference between a legal test and a home test?

The laboratory testing processes for Court Approved and Peace of Mind DNA tests are exactly the same. The difference is that Court Approved tests require a witness, proof of identity and special chain of custody procedures. A Peace of Mind DNA Test is not legally binding because there is no proof that samples have been collected from the correct participants.
The Peace of Mind test is intended to be a discreet and private way of allowing families to resolve any questions without involving other parties.
