Each participant provides a painless cheek swab sample at home. Our state-of-the-art laboratory performs an advanced analysis comparing the genetic profiles of the grandparent(s) and the child. The results include a grandparentage index that measures the statistical likelihood of a biological relationship. Results are delivered in 2-3 business days.
A grandparent DNA test can provide strong evidence of a biological relationship between a grandparent and grandchild, which indirectly supports or refutes paternity. Testing both grandparents produces the strongest results. Including the mother's sample can further improve accuracy.
Testing both grandparents significantly strengthens the analysis. When only one grandparent is available, accurate results are still possible, but including both provides the most conclusive evidence. You can add additional participants when ordering.
