A DNA test can be used to either:

  • prove that 2 people definitely are not related
  • show the probability that 2 people are related

You’ll need to give either a blood or saliva sample.

What you can use a DNA test for

DNA tests can be used to:

  • solve a dispute about child maintenance
  • apply for contact with a child
  • apply for a visa so that a child can settle with you in the UK
  • find out who inherits an estate when someone has died

Booking a test

You can arrange a DNA test yourself.

Depending on what you’re collecting DNA evidence for, you’ll need to check you’re going to the correct laboratory.
