What is Grandparent DNA Test?
A Grandparentage DNA test is a DNA test that determines if an alleged grandparent and grandchild are biologically related. This testing option is performed when an alleged father is unavailable to participate in the DNA testing process. For increased testing analysis accuracy we recommend the mother of the child be added to the test.
We understand the importance of establishing a child’s paternity. When an alleged father is unavailable to perform a paternity test, a Grandparent test is an effective alternative testing option to help determine paternity. At IDTO DNA, we take pride in providing accurate and affordable testing services to help families confirm biological relationships.
