Grandparentage DNA Testing in Riverside, San Bernardino Counties and San Gabriel Valley

Affordable Grandparentage DNA Testing

DNAGrandparentage DNA Testing is often one of the better relationship DNA tests to perform to determine paternity of a child if the alleged father is deceased.



The best testing scenario is a test that includes the mother, child and both of the alleged father's parents. By including both of the alleged father's parents, the alleged father's DNA profile can be reconstructed. Comparing the alleged father's reconstructed profile against the child's DNA, can allow this testing scenario to give results as accurate as a paternity test.



A test can be done if only one paternal grandparent is available, although it is recommended that both paternal grandparents test. With only one paternal grandparent, the missing fathers DNA cannot be reconstructed. In this situation, the paternal grandparent and child will be tested and their genetic information will be compared.



Grandparents seek DNA testing on their grandchildren for 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. 

With a Grandparentage DNA Test, you can conclusively determine if a child is your biological grandchild or not.
