What if the father is missing or deceased?
Several DNA testing options are available if the father is missing or deceased: viability test, grandparentage, and genetic reconstruction.
If an alleged father is deceased, we might be able to use some biological samples, such as a preserved tissue sample from a coroner’s office. We need to first perform a viability test to determine if there is enough useful DNA in the sample. If enough useful DNA is present, we can use this sample and proceed with the standard paternity test. Please call us at 1-888-362-2592 to discuss this possibility with an experienced case manager.
If no biological samples from the father are available, we can look at close family members to determine if a child belongs to that family. A grandparentage test is the first option to try. The following persons must be tested:
Paternal grandmother (Alleged father’s mother)
Paternal grandfather (Alleged father’s father)
Child
Child’s mother
If the paternal grandparents are not both available, the next option is a genetic reconstruction. At least two close relatives of the alleged father are needed to participate in this test. A close relative is a full brother/sister and/or a biological parent of the deceased/missing alleged father. In addition, the mother and child must participate. The result of this test will show the probability that the child is related to the tested parties.
