Relationship Tests
Have you been questioning your biological relationship to another relative? Do you need absolute certainty that you are biologically related? Our relationship DNA test could provide the answers you need.
Why use a relationship test?
DNA relationship testing can be used to verify the existence of biological relationships between relatives. We offer different types of relationship tests including Sibling DNA testing, which can be used to confirm whether alleged siblings are related or not. Relationship tests can also be extended to include other family members, such aunts/uncles and grandparents.

Grandparentage Test
As part of our portfolio of relationship tests, the grandparentage DNA test can be used when grandparents need to confirm the biological relationship to their grandchild. This test shows the statistical probability that the grandparents are genetically related to their grandchild.
- A simple and fast test
- Bypass the parentage test

Human DNA Tests
Aunt & Uncle Test
The aunt-uncle DNA test (or avuncular test) will determine whether a genetic relationship exists between aunts and/or uncles and their niece and/or nephew. Avuncular test results will show you a probability of relationship between tested parties.
- Avuncular test results
- A user-friendly home kit

Human DNA Tests
Mitochondrial DNA Test
MtDNA testing is the ideal test for you if you wish to establish whether you and another person/people share the same maternal line, for example the same mother, grandmother, great grandmother etc. MtDNA rarely undergoes genetic mutations and thus, offers very accurate results.
- Highly accurate results
- Discover shared maternal lines
from $349
Human DNA Tests
Y Chromosome Test
Y chromosome testing is done when two or more male individuals wish to confirm whether they share the same father or if they have a common paternal relative. This test, carried out exclusively between males, is a highly accurate and conclusive sibling test.
- Establish your paternal line
- Quick and painless
from $299
Human DNA Tests
Genetic Reconstruction Test
A genetic reconstruction test is designed to establish if a child is biologically related to direct blood relatives on their father’s side of the family. The test is performed when the father in question cannot be directly involved in the test and a direct father-child paternity test cannot be carried out.
- Confirm your biological paternal line
- High-quality results with a convenient home kit
from $433
Human DNA Tests
Maternity Test
Proof of maternity/evidence of the biological relationship between mother and child can be provided with a DNA maternity test. Affordable and with highly accurate results, our maternity test will provide the answers you need in just 3-5 working days.
- Results in 3-5 working days
- Affordable and highly-accurate results

A Note About Relationship Tests
Relationship testing is particularly useful in situations when the alleged father is not available for a standard paternity test and the siblings want to establish whether they share the same father or not. It is also possible to use other members of the family, such as aunts, uncles, nieces or nephews, to determine whether there is any biological relationship. These tests are more complex than paternity tests; moreover, the type of test will depend on who is available for testing and their sex.
DNA relationship testing can be used to verify the existence of biological relationships between relatives. Types of relationship tests include Sibling DNA testing which can be used to confirm whether alleged siblings are related or not. Relationship tests can also be extended to include other family members such as aunts/uncles and grandparents.

For instructions on how to collect your samples visit our DNA sample collection guide. If you need to submit a sample other than an oral swab, we suggest that you read the information we provide about our DNA forensic testing services.
Our sample collection kit, used for both legal and home paternity testing, enables you to collect cheek cell samples using sterile oral swabs (note that prenatal testing is an exception and is done using blood samples).
The procedure is done in a matter of seconds and is absolutely painless. We encourage using oral swab samples where possible as we have a very high probability of successful DNA extraction with these samples. If you are unable to provide us with oral swabs, then you might want to consider our forensic DNA testing services for forensic samples as an alternative.
Your user-friendly, home DNA sample collection kit is sent to your preferred address. Kits can be posted anywhere in the UK, including Northern Ireland, Wales and Scotland. After yous DNA samples are received, they are always processed in an ISO 17025 accredited laboratory. Finally, your results are sent by email within 3-5 working days.
We offer home, legal testing, prenatal testing as well as immigration testing for paternity. EasyDNA has completed successfully more than 300,000 tests in our 10 years of experience.
Our home DNA test starts from as little as £99. This all inclusive cost covers:
- Your complete, user-friendly, home DNA sample collection kit is sent to your preferred address. We can post your kit anywhere in the UK, including Northern Ireland, Wales and Scotland.
- Analysis of your DNA samples in an ISO 17025 accredited laboratory.
- Your results, which are sent by email. (Note that hard copies can be sent at a small additional cost).
EasyDNA carries out many of its paternity tests without the mother’s sample. However, we urge our clients to send the mother’s DNA sample when and if she is available. This will help us give you results with a higher of probability of paternity. Testing of the mother comes at no additional charge. Read more information about testing the mother’s sample.
To be noted that the NHS does not provide free paternity DNA testing.
Under section 45 of the Human Tissue Act, it is an offence to take any human tissue or DNA sample from a person without their qualifying consent. The person from whom the sample is taken must also be made aware of what that DNA sample or human tissue will be used for.
This law applies to the whole of the UK. Please ask us if you need any more information on the Human Tissue Act.
