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. Getting a test that establishes the biological father of a child is easy and simple. With the paternity test, there is also the choice of peace of mind DNA testing or legal paternity testing.
How does a Paternity Test work?
We analyse specific genetic markers in each person’s DNA profile, identifying two alleles at each location—one inherited from the mother and one from the father.
The process begins by comparing the mother’s DNA profile with the child’s. At each marker, one of the child’s alleles will match the mother’s. The remaining alleles are then compared to the putative father’s DNA. A complete match across all markers confirms the biological relationship, as the father contributes these alleles at conception.
If mismatches occur, the individual is excluded as the biological father, as only their own alleles can be inherited by their child.
Frequently Asked Questions
How long does it take to get the Paternity test results?
The average analysis time in the lab is around three working days. However, 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 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. A motherless paternity test can be undertaken, but you must be aware that we will report a lower statistical percentage.
How do I order a Paternity Test?
Here are the options available to you:

How accurate is the Paternity 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.
