Why use a relationship test?
These tests are suited in instances when one of the alleged parents is not available for a DNA test and thus, carrying out a straightforward parent-to-child DNA test is not possible. For example, a DNA siblings test can be performed to establish if a biological relationship exists between potential siblings in cases when the alleged father is not available for testing.
Are you really siblings? Do you share the same parents? Siblings DNA testing is ideal in situations where alleged siblings (brothers and sisters) want to confirm their biological relationship and verify if they are full siblings, half siblings or not siblings at all.
Find out if twins are identical or fraternal accurately and scientifically. EasyDNA offers our twin DNA test to help confirm whether twins are identical twins (monozygotic twins) or fraternal twins (heterozygotic twins). Results for our twin DNA test are 100% accurate.
Are they your biological grandchildren? Grandparentage DNA testing is a type of relationship test carried out between grandmother, grandfather and grandchild to confirm whether the grandparents tested are the biological grandparents of their grandchild.
Doubts about your genetic relationship to your relatives? Relationship queries between aunts and/or uncles and nieces and/or nephews could be solved with avuncular DNA testing which determines the probability that people tested are truly the blood relatives.
Do you need to find out if you share a common maternal ancestor? If this is your case, an MtDNA test is the right test for you. MtDNA testing (mitochondrial DNA testing) is used to determine whether two or more people have a common maternal lineage.
Are you 2 or more males that need to know if you share the same biological father, grandfather or male relative? If this is your case, then this is the test you need. A Y chromosome test is ideal to test a common patrilineal line between male.
Are you females with different mothers who need to find out if they have the same father? If this is your case, the X chromosome test is the ideal test. This test is based on the analysis of the X chromosome profile and uses 10 genetic markers.
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.
Do you need to prove that your children are your biological offspring? A DNA maternity test is used to prove the existence of a biological relationship between an alleged mother and a child. The results guarantee a 99.99% for inclusion of maternity and 100% for exclusion.
A note about relationship tests
Relationship testing is slightly more complex than standard paternity testing and can be used to determine various types of relationships in different situations. Depending on the people available for the DNA test, there are several different methodologies that can be used according to the alleged relationships. Relationship testing is often carried out in the place of a paternity test. Participants often want to establish their biological relationship to the alleged father without testing the alleged father. However, if samples can be collected from the putative father, we recommend a paternity test. More information about this can be found on our website.
