The Duo Grandparent test can be used as an indirect way of establishing paternity. For example, in the father's absence, we can use a DNA samples from his biological parents to establish paternity. If both potential grandparents are available for testing, then you should choose the Duo Grandparent test rather than the single grandparent test, as it provides a greater chance of receiving conclusive test results.

You should only use the Duo Grandparent DNA test if it is not possible to get a DNA sample from the potential father. If the potential father is available, then you should consider a Paternity DNA test. Paternity DNA tests are available from DNA Clinics and boots.com

IMPORTANT:

We recommend including a DNA sample from the child’s biological mother, as this will reduce the chance of an inconclusive result. There will be no additional charge to include the mothers DNA sample, but fees will apply for any additional test participants. Please contact us if you require additional mouth swabs to include further test participants or would like to discuss which option best suits your circumstances.
