can a grandparents dna be used to prove paternity
Special Services - DNA Grandparentage Test. A grandparentage test is used to determine whether a grandmother or grandfather is the true biological grandparent of a child. A grandparentage test is usually used when the parent of the child is not available for testing. In situations where the alleged father is unavailable for testing (e.g. alleged father is deceased or unwilling to participate), the alleged father's parents can be tested to determine whether they are the true biological grandparents of the child.
