Relationship DNA tests are often used to determine paternity when the alleged father is deceased, unavailable or unwilling to take part in a test but relatives such as the alleged father’s brother, sister, parents or the child’s sibling are available.

A paternity test would provide more conclusive results but can only be carried out if we can obtain DNA samples from the alleged father.

Please see below for more information about the relationship tests we offer including a sibling DNA testing kit, twin DNA testing, DNA testing for grandparents, a DNA test for aunt or uncle and our maternity DNA test.

Y chromosome testing, or Y-DNA testing, will confirm whether two males are from the same paternal line while a mitochondrial DNA test, or mtDNA test, will confirm if two participants (male or female) are from the same maternal line.

We also offer Surrogacy DNA testing for situations that require a DNA test for an IVF baby or for adoption and a genetic reconstruction DNA test that can be used to establish paternity or maternity when the alleged father or mother is not available.

Please see below for more information about all our relationship DNA tests.
