DNA Tests Available > Cousin DNA Testing
The Cousin DNA test will establish whether two individuals share a common ancestor – which makes them first cousins, second cousins, third cousins, fourth cousins or even fifth cousins. Cousin DNA testing should only be used when closer relatives are not available for testing in order to establish the link.
The Cousin DNA Test can accurately identify relationships as far removed as 5th cousins. The DNA Clinics DNA test is the most detailed and accurate Cousin DNA testing service available.
A cousin is technically a relative with whom a person shares a common ancestor, when that ancestor is not a parent, sibling, child of a sibling, or sibling of a parent. The most popular and well known form of cousinship is ‘first cousins’ when the two individual share the same grandparents.
As a relationship between two people becomes more complex, it becomes more confusing as to what the potential relationship is that exists.
Tracking individuals through a family tree can help establish where the potential link between two people lies.
There are ‘levels of cousin’, or ‘degrees of cousinship’ and also ‘removals of cousinship’. These terms can cause further confusion and it is important to establish exactly what the potential relationships are before ordering a Cousin DNA test.
If you would like some guidance on how to check the level of cousinship, please follow the link below:
This Cousin DNA test can be performed between individuals who believe they are related to a common ancestor and accurately identify the relationship between the two participants as far removed as 5th cousins.
There are many varieties of Cousin DNA Testing, depending on the situation known:
At DNA Clinics, a Clinical Advisor will work with you to establish exactly what the situation is and what the known facts are, thus determining the correct form of test for your family.
The test analyses up to 720,000 DNA markers on the DNA strand for each test participant. These markers are compared and the matches calculated to provide evidence of what relationship most likely exists.
The test is based on the fact that the closer related and individual is to another person, the more DNA they will have in common.
Paternal and Maternal lines can also be mapped using Y Chromosome analysis and Mitochondrial DNA tests.

If siblings are available for testing then Sibling DNA tests should be used if possible. In addition, despite the accuracy of Cousin DNA tests, no DNA test can replace the tests that directly test the DNA of a biological parent. If it is the father of a child that is in question, then a Paternity test should be used if possible and forensic testing considered if samples are available.
Whether a different DNA test is recommended by your Clinical Adviser, will depend on the question you are trying to find answers to and who or what samples are available for testing.
Are we first or second cousins? Are we related? How can I prove we are cousins?
Are we third cousins? Is he my cousin’s son? Is she my cousin’s daughter?
Is she her father’s cousin? Is he her father’s cousin?
