Family Relationship DNA

DNA family relationship testing can determine if siblings are unrelated or half vs half or full siblingship. It can also assist the biological links between the relatives; including siblings, grandparents, uncle or aunt.

If the father is deceased, or not willing to be tested.  A grand-parentage test can be done with one or both Maternal or Paternal grandparents. If alleged father is deceased and an autopsy was completed we  work with the coroners to get samples for testing.

Accurate DNA relationship testing collect the sample from the child’s mother as well as from both paternal grandparents. The same principles can be applied to prove maternity by testing the child’s father and maternal grandparents.
