Paternity Testing

What Relationship does Paternity Testing Prove?

Paternity Testing determines whether a man is the biological father of the child or children in question. The test compares the DNA of a mother, a child (or children) and a possible father.

Children inherit half of their DNA from their mother and half from their father. If a man shares certain DNA sequences with a child then there is a 99.99% chance the man is the biological father of that child. If a man does not share those DNA sequences with a child then he is not the biological father.

Which Family Members should take the Paternity Test?

For a Paternity Test from NorthGene, we need DNA samples from the mother, child (or children) and the possible father.

We can proceed with DNA from just the father and child but any children under the age of 16 must have the mothers consent to take the test. If the UK Courts have ordered the test or the father has parental responsibility we can proceed without the consent of the mother.

Are the Paternity Test Results Conclusive?

The Paternity Test result will show either:
– the man is 99.99% likely to be the biological father* of a child or
– the man is definitely not the biological father.

*Paternity Testing can never be 100% certain that a man is the biological father of a child. This is because of the large number of genes shared within the general population.

On rare occasions (in cases where the test is between a single parent and child), the DNA profiles which NorthGene analyse do not generate a strong enough statistic to produce a conclusive outcome. In these instances our team will recommend either the participation of the other parent or the use of a more sensitive testing kit, however this will incur an additional charge.

One Final Note

If a close male relative* of the man tested is a possible father of the child, that relative must also take the test. This will ensure the accuracy of the result.

*A close male relative is a father, brother or son.
