Other DNA Tests When Father Isn’t Available
If the alleged father is deceased, unavailable or simply refusing to be tested other members of the family can be tested to determine a biological relationship.
This is one of the best DNA tests to use when the alleged father is unavailable for paternity testing. It is best to have the mother, child and both paternal grandparents however testing can be done with only 1 grandparent. This test is accepted by social security if the father has passed away.
Testing Brother and/or Sister (Siblinship)
If you want to know if 2 children share the same mother or father but the parent in question isn’t available for testing we can compare the DNA between the 2 siblings. It is always best to have any known parents included in the test. We all get half of our DNA from our mothers and the other half from our fathers. Whenever possible we want have at least one known parent to include in a siblingship however it is not a requirement.
Testing an Aunt or Uncle
An avuncular test can compare a child’s DNA to an alleged aunt or uncle to see there is enough DNA in common to determine their relationship.
