Grandparent DNA Test

Grandparent DNA testing can be very valuable in terms of establishing relationships. Any time the alleged father of a child is not available for testing, the next best type of testing is a grandparent DNA test using both of the alleged father’s biological parents. With both of the alleged father’s biological parents involved, we essentially have 100% of the alleged father’s DNA. Typically, we can compare the child in question to both alleged paternal grandparents without testing the mother. In the event that a test containing both biological parents of the alleged father does come back inconclusive, which is rare to begin with, we can add the mother of the child into the test to strengthen the result. If and when both biological parents of the alleged father are not available, we can use one. When comparing one grandparent, either the grandfather or grandmother, to the child, we prefer to add the mother of the child into the case initially in order to lessen the likelihood of an inconclusive result. If the mother of the child is not available, we can test only one grandparent and one child, however, the probability of an inconclusive result is much higher.

A grandparent DNA test is helpful any time the alleged father of a child is either not available for testing or if he refuses to be involved in the test. If you are having DNA testing performed for any legal or paperwork purpose, such as for survivor benefits in the case of a deceased alleged father, please verify first that the organization you are working with will accept test results from a grandparent DNA test. In some cases, they will not.
