DNA testing on their grandchildren for either of two
common reasons: they have doubts about the paternity
of their son's or daughter's child, or they would like
to prove that they are related to a grandchild whose
family denies the relationship and bars them from developing
a relationship with the child (Read
more about these situations.
) With a DNA grandparentage test, you can
conclusively determine if a child is your biological
grandchild or not.
testing is usually performed when the possible
father is not available for a DNA
paternity test. In such cases, we can test the biological parents of the possible father and compare their DNA with the child's
DNA to see if the possible grandparents have passed down
their genetic material to the child through the
father. Conversely, we can also test for maternal
grandparentage to confirm biological relationships
in situations where a mother and child were separated
early in life, but the mother is no longer available
for a maternity test.
