DNA testing for paternity is the most accurate scientific method of determining a biological relationship between children and their father.

AlphaBiolabs offer two different types of paternity test.

1. Peace of mind DNA testing for paternity

Our peace of mind DNA test is the UK’s most popular home DNA testing kit. If there are doubts around a child’s biological father, this quick and affordable test can help to provide you with an answer.

Simply order your paternity test and post your cheek cell samples back to us. Your samples will be analysed in-house at our award-winning UK laboratory, and your results will be sent to you the next working day via email. You can also pay an extra £70 to receive your results on the same day if you don’t want to wait.

2. Legal DNA testing for paternity

Our legal DNA tests can be used as evidence in family court cases. This means that they must be performed under specific instructions called chain of custody.

Under a chain of custody, a trained sample collector ensures that the correct individual is providing the DNA sample by checking their ID, taking photographs and obtaining signed paperwork. The samples are then sealed to prevent tampering attempts.

A legal paternity test can still be performed in your own home, but a trained sample collector needs to attend. You can also provide your DNA samples for free at one of AlphaBiolabs’ Walk-in centres.

How does DNA testing for paternity work?

A paternity test proves parentage by analysing cheek cell DNA. When we examine the specific DNA markers in each sample, we can identify which half of a child’s DNA is inherited from the mother, and which half is inherited from the father.

When testing a biological father, both the child and their father will share identical sections of DNA at each marker. If the man tested is not the child’s biological father, there will be differences in the DNA.

How accurate is DNA testing for paternity?

Based on the samples we receive, our paternity test results are 100% accurate. We test all of our exclusion results twice, so you can be confident that the result you receive from us is completely accurate. We’re also a trusted UK laboratory, and our processes are UKAS accredited to give you total peace of mind.
