Grandparent DNA Testing from DNA Laboratory DNA Security

When the father of a child is not available for DNA testing, the grandparents can be tested. This DNA test is possible because if the grandparents are the biological parents of the biological father of the child, then they possess the same paternal genetic markers of the child in question. The genetic analysis for a grandparent test is the same as that used in our standard DNA Paternity Test. For cases when the grandparents are not excluded, a probability of grand parentage is determined.

Establishing Paternity & Grandparent age - How does a DNA Test work? When the mother of a child and both grandparents are tested along with the child, then the power of this DNA test is comparable to a paternity test that includes the alleged father. If the mother is not available for analysis the test is slightly weakened and is comparable to a standard paternity test when the alleged father is tested, but not the mother. If only one of the grandparents is available for testing then the power of the DNA test is substantially weakened. When only one grandparent is tested it becomes impossible to exclude the child as the grandchild. This is because if the tested grandparent does not contain the required paternal genetic marker, the paternal marker may be present in the absent grandparent.

DNA Security, Inc. is proud to make available the EASY ANSWERS DNA test kit to provide individuals with a choice regarding privacy when resolving genetic issues, such as determining grand paternity.
