divider-line-955DNA Family Relationship Testing

DDC is best known for its family relationship testing services. Our laboratory offers the following relationship DNA tests:

  • Parentage tests, including paternity and maternity testing
  • Siblingship
  • Grandparentage
  • Twin zygosity
  • Genetic reconstruction and family studies

A unique feature of DDC’s family relationship DNA tests is the DualProcess™, a comprehensive strategy to reduce errors in testing. All samples we receive are processed for independent testing by separate technical teams. They carefully record each step to ensure that samples are properly identified and tracked throughout. At the end of the process, our laboratory directors review the raw and analyzed data produced by both teams, ensuring the results match. The DualProcess™ eliminates common laboratory mistakes and assures clients of accurate, reliable results.

In addition to family relationship testing, DDC offers recreational ancestry testing services through its subsidiary, Ancestry by DNA™.
