Grand-parentage DNA testing


Grand-parentage DNA testing

The DNA Bioservices Grand-Parentage testing is designed for definitive answers when establishing a relationship between an individual and an alleged grandparent. Our simple collection kit is fast and easy.

There are two different types of Grand-Parentage testing.

Single Grand-parentage DNA Analysis:

  • This DNA test includes ONE grandparent, one grandchild, and a parent (optional but strongly suggested). The conclusive range for DNA results are either >90% (inclusion) or <15% (exclusion) probabilities.
  • However, results may vary between 1% and 99% accuracy.

Duo Grand-parentage DNA Analysis:

  • This DNA test includes BOTH grandparents, one child, and parent optional, but strongly suggested.
  • For the most accurate results in a grand-parentage analysis, it is best to include both the alleged grandparents and the child.
  • When both alleged grandparents are included, the DNA results are guaranteed to indicate either >99% (inclusion) or 0% (exclusion) probability of the Grand-parentage relationship
  • Grand-Parentage Testing is for clients who want to determine parentage when an alleged father is unavailable, and no post mortem sample is available.
  • Samples can be used from grandparents to reconstruct the alleged father's DNA pattern.
