Relationship DNA Tests

We offer a comprehensive range of Relationship DNA Tests including Siblings, Twins, Maternity, Aunt, Uncle & Grandparent testing.

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.

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

Dog Allergy Testing Kit Review
Hello Team, I would love to thank all involved in testing my dog allergies. Since that test she finally lives her life itch free as it enabled us to avoid products causing her allergic reaction. I am very grateful for this report as her health massively improved after we removed all listed products from her diet. Since that time I have been suggesting other dog owners which battle similar issue to use your service. 5* from Blue.

Dog Allergy Test Kit Review
We had our dog allergy tested with you last year. We were advised that it is not a good enough test by our vet and many others online. This however couldn't be more wrong. We used the results to remove foods from her diet and even hypo-allergenic shampoos etc. Since she turned 1 years old we had her allergy tested by blood at the vet to see if she had out grown any of these allergies. The results were exactly the same as we were given by yourselves. Everything in red she is still allergic to. Without your help I'm not sure how we would of been able to help her in her first year. Especially given that she is allergic to almost everything hypoallergenic.

Dog Allergy Testing Review
Please forward my praise to your superiors with regards to your customer attention - thank you for all the communication at all times, and making sure all OK. Much appreciated. 1 day into eliminating salmon oil from her diet (daily supplement I was giving her for for her arthritis) and the turkey menus she is considerably better, all in 24 hrs. Can’t wait to see how she improves within a few weeks of elimination.
