Kinship Tests

What is it?

A DNA kinship test will test the relationship between two or more individuals to assess if they are biologically related. Examples of the types of relationships that can be tested include:

  • Grandparents compared to a grandchild
  • Aunt and/or uncle compared to a niece and/or nephew
  • Full siblings
  • Paternal half siblings
  • Maternal half siblings

NOTE: A kinship test is often more complicated than a standard paternity or maternity test and may involve more consultation with LabCorp’s knowledgeable customer service staff to ensure that the most appropriate individuals are being tested.

Why should I use it?

Kinship tests are used to provide reliable parentage testing when one parent is deceased or unavailable.

Kinship tests are often performed for people seeking a Green Card who have a family member that is a US citizen. There are certain instances in which it will be beneficial to test individuals other than just the Petitioner and Beneficiary in Green Card requests. More information about this process is available on the US Citizenship and Immigration Services (USCIS) Web site.
