Paternity DNA Testing

The Paternity test is the most popular form of DNA test performed at DNA Clinics. Also, our kits are sold in partnership with Boots, making them the No. 1 best-selling paternity test kit in the UK. So getting a test that establishes the biological father of a child is easy and simple. In addition, there is also the choice of peace of mind DNA testing or legal paternity testing.

How does a Paternity DNA Test work?

We analyse a number of genetic ‘locations’ in each person’s DNA profile. Each person possesses two (of many possible) alleles at each genetic location. We identify the alleles using numbers. These ‘numbers’ come from the parents at conception. One comes from the mother and one from the father. In turn, we can create a list of numbers for each person taking part in the test.

First, we compare the DNA profiles of the biological mother and child. At each location, one of pairs of the child’s numbers will match up with a number from the mother’s sample. Next, we then compare the remaining numbers from the child with the putative fathers. If he is the biological father, the remaining numbers should match up with each number from the child’s sample.

We will include the person as the biological father of the child if the numbers match at all locations. This proves they have passed these genetic markers to the child at conception.

In turn, locations where there is no match, we will exclude a person as the biological father. This is because it is only possible to pass on to your children the alleles which you have in your own DNA.

Frequently Asked Questions

How long does it take for the Paternity DNA test results?

The average analysis time in the lab is around three working days. But this does not include the quality checks needed for sample integrity or your consent paperwork. So, from receipt of your samples at Crystal Health Group, it takes on average of about three to four working days. If there are any unforeseen delays, for example, such as the paperwork we receive not being quite right, we will contact you as soon as possible to let you know.

Does the mother need to take part in the Paternity DNA Test?

Providing you with the answers you need is our number one priority. As a result, we recommend that you include the biological mother of a child in your paternity test. Also, there is no additional charge for this as it improves the accuracy of the result. As mentioned, a motherless paternity test can be undertaken, but you must be aware of the lower statistical percentage given.

How do I order a Paternity DNA Test?

Here are the options available to you:

* Please note, you can only use self-collection kits for peace of mind purposes only. This test cannot be used for legal purposes.

How accurate is the Paternity DNA Test?

Paternity testing has come a long way since the early 2000s. The improvements in testing methods and lab equipment means that test results are extremely accurate. For example, for a positive paternity test result, we provide up to a 99.9999% probability for inclusion for a biological father. In other words, this person is at least 1 million times more likely to be the biological father of the child tested rather than an unrelated individual from the same ethnic group. Also, this relates to a test which includes the mother’s DNA sample.

When the mother is not tested, this percentage can decrease to 99.99%. But we will still report this as a positive paternity result. This is because this is still a high percentage of probability and practically proves paternity.

So, what about a negative result? The probability is 0% when excluded as a biological father. This means that there is zero percent chance that the person tested is the biological father of the child.

What if any alleged fathers are related?

In this case, you must discuss the situation with our Clinical Advisor Team. For example, the situation might be that potential fathers are brothers or father and son. However, we might still be able to undertake this test for you. A Clinical Advisor will talk you through the options available.

Local DNA Clinics, and mobile locations throughout the UK

For your convenience, we have a network of DNA Clinics throughout the UK. As a result, we can provide paternity test appointments for you in your local area. Alternatively, we can arrange for a certified sample collection officer to visit your home or other convenient location of your choice.
