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.

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