Establish biological relationships through grandparents when a parent is unavailable or deceased.
A Grandparentage DNA Test determines whether a child is biologically related to one or both grandparents. This test is commonly used when the alleged father is unavailable, deceased, or unwilling to test. By analyzing the DNA of the child and one or both paternal grandparents, we can establish a biological connection with a high degree of probability.
This test is ideal for families where the alleged father cannot be tested and grandparents are available. It is frequently used in inheritance disputes, immigration cases, and for personal peace of mind.
Our mobile collector meets you at a scheduled appointment and collects painless cheek swabs from the child and one or both grandparents. Adding the mother's sample increases accuracy. The visit takes about 15 minutes. Results are available in 3–7 business days.
Probability results vary based on which family members participate. Testing both grandparents plus the mother yields the highest probability of relationship.
Establish legal fatherhood with a court-admissible, chain-of-custody paternity test yielding 99.99%+ probability of paternity.
Get the same 99.99%+ accuracy for personal knowledge — without the legal chain-of-custody requirements.
AABB-accredited DNA testing accepted by USCIS, U.S. embassies, and immigration authorities worldwide.
