Legal Relationship Test

Our Relationship test is performed to determine whether two or more individuals are biologically related.

We compare the DNA of two people to determine which relationship is best supported by the amount of DNA they have in common. For example, if two people are known to share the same mother, our Relationship DNA Testing can be used to indicate the likelihood of them having the same father. We can see if their DNA profiles are more consistent statistically with them being half-siblings or full siblings.

A wide range of relationships can be considered and the testing can be performed on males and females (grandparents-grandchildren, siblings etc).

DNA Solutions Pty Ltd is Accredited for Relationship Testing, our Relationship DNA Tests are valid for:

- Immigration purposes

*Test performed according to the Australian Family Law Regulations*
