Have you been questioning your biological relationship with another relative? Do you need absolute certainty that you are biologically related? Our relationship DNA test could provide the answers you need. 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 as aunts/uncles, and grandparents.
