DNA Test For Siblings |
Full or Half DNA Testing

sibling dna testing

Sibling DNA testing can be done on alleged siblings to determine if they are half-siblings or full-blooded siblings. 

Legal Sibling DNA tests are similar to a legal paternity test that a legal chain of custody is established. Building a chain of custody contributes to your DNA test result being a legally admissible document. Here are a few circumstances where a legal Sibling DNA Test may be used.

1. Immigration

2. Social Security when an alleged biological father is deceased.

3. Adoption 

These are some of the most common scenarios when legal Sibling DNA Testing is used.
