Relationship DNA Testing in San Antonio South

DNA relationship testing can be used to determine whether biological links between relatives really exist. Biological mother and father relationships are usually determined with a direct test, but if the parent is absent or has died, less direct relationships, such as siblings or grandparents, can be used to make the determination. This type of test can be performed between siblings, grandparents, aunts and uncles.

The science of DNA analysis and testing has advanced so far that confirming the existence of biological relationships is much easier and more certain than ever before.

Paternity Testing

Our paternity testing lab will help you prove the paternity of your child with a court admissible paternity test that can be used in any court in the United States.

Grandparent DNA Testing

Grandparent DNA testing determines the statistical probability of the alleged grandparent being a child’s biological grandparent. Testing the paternal grandparent(s) is a preferred method to determine parenity when the father is not available for testing

Court-Admissible vs. Non-Court Admissible

You may need proof that a biological relationship exists — or not — to get benefits or be released from having to pay. If so, you need to make sure your DNA test results are admissible in court.

Siblingship Testing

Siblingship testing provides additional evidence of family relationships when an alleged father is unavailable for paternity testing

Maternity Testing

Like paternity testing, maternity testing compares a child’s DNA pattern with that of his or her alleged mother.

Twin Testing
