Home Grandparent DNA Test

A grandparent DNA test can determine whether a child is biologically related to a set of grandparents.The test is often performed when a child’s alleged father is unavailable for paternity testing and the child’s grandparents have doubts about whether the child is truly related to them.

A grandparent DNA test is based on the fact that a child inherits half of his or her genetic profile from each biological parent. When one of a child’s parents is missing or deceased, we can look to the grandparents to determine if they contributed DNA to the child’s genetic profile.
