If the alleged father is deceased, forensic DNA testing can be considered using items which may contain the alleged father's DNA. Forensic DNA testing can be performed any anything that has biological material from the father such as an old toothbrush, electric razor, blood stains, saliva stains, and bone or teeth from an exhumation. If it is not possible to obtain a forensic sample for the alleged father, testing his direct relatives can be considered. If his parents are alive, the grandparentage test can be performed. If he has any siblings, then an aunt or uncle test can be performed. If the alleged father has other children, then a full or half sibling test can be performed.
