There are two different types of Grand-Parentage testing:


This DNA test includes ONE grandparent, one grandchild, and 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.


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 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
