Family Relationship DNA Tests from £190
We offer a comprehensive range of family relationship DNA tests to help determine biological connections when direct paternity testing is not possible.
Siblings DNA Test
We provide both:
-
Full Siblings DNA Test – determines whether two individuals share both biological parents
-
Half Siblings DNA Test – determines whether individuals share only one biological parent
These tests analyze up to 25 genetic markers and calculate the probability of biological relationship based on shared DNA.
Grandparent DNA Test
A grandparentage DNA test is used to establish a biological relationship between grandparents and their suspected grandchildren.
-
Testing both grandparents is recommended for increased accuracy
-
Testing can also be performed with one grandparent only
For cases involving a grandfather and grandson, we recommend a Y Chromosome DNA test to confirm paternal lineage.
Avuncular DNA Test (Aunt/Uncle Test)
The avuncular DNA test determines whether an individual is biologically related to a child as an aunt or uncle.
This test:
-
analyzes up to 25 genetic markers
-
compares the DNA of the alleged relative (aunt or uncle) with the child
-
helps establish indirect paternity relationships
Cousins DNA Test
A cousins DNA test can help determine whether two individuals share a common family line when closer relatives are unavailable for testing.
Additional DNA Tests Available
We also offer specialized DNA tests for more precise lineage analysis:
-
Y-STR (Y Chromosome) DNA Test
-
recommended for male individuals
-
determines shared paternal lineage
-
-
X Chromosome DNA Test
-
useful in specific cases, particularly for female lineage analysis
-
helps determine shared biological father in certain scenarios
-
-
mtDNA (Mitochondrial DNA) Test
-
traces maternal ancestry
-
confirms a common maternal ancestor
