DNA Relationship Testing

Establishing the existence of biological ties with potential relatives outside one’s immediate family can be done through DNA Relationship Testing. This type of test can be used to establish the existence of biological relationships with potential aunts, uncles, nephews, nieces and grandparents.

DNA relationship tests are normally carried out when the biological parents of a child are not available for testing or are unwilling to do the test. We do not usually recommend carrying out a relationship test if testing one of the parents is possible.

If two alleged siblings want to confirm whether they share the same father, but do not have the option of carrying out a straightforward paternity test, they can opt for a Siblings Test to determine whether they share the same biological father. Another alternative would be testing other relatives of their father to find out if they have genetic material in common by carrying out an Avuncular test (aunts or uncles) or perhaps a Grandparentage Test.

The first thing we will need to know when you require a DNA relationship test is who is available for testing and their gender. This will enable us to recommend the type of test best suited to your needs.

Below is a list of the relationship DNA tests we offer:

• DNA Siblings tests - This type of test will establish whether you are full siblings, half siblings or not related at all. There are 4 main types of siblings tests – read more to find out which one is most suited to your particular needs.
  
• DNA Grandparentage test- This test will compare the profile of genetic markers of the child with that of the alleged grandparents. If there is a biological relationship between them then this will confirm in turn that the grandparent’s child, i.e., the alleged father is the biological parent of the child tested.
   
• DNA Avuncular test - a means of establishing paternity by testing the alleged father’s siblings (i.e. alleged aunt and uncle) together with the child.

The following are the different types of DNA testing methodologies adopted in relationship DNA testing:

• STR analysis - this type of test will establish if a biological relationship exists between two people through the comparison of their genetic profiles.
• Y-chromosome testing- this type of test is done to establish if two males are in any way related from the father’s side of the family.
• X-chromosome testing-determines if alleged sisters have the same father;
• MtDNA test - used to establish if a biological relationship exists between two persons through the mother’s side of the family.
