If the alleged father is unavailable for testing, grandparentage DNA testing can provide a reliable alternative for determining biological relationships. By testing one or both alleged grandparents, DNA Vue can help establish whether a child is biologically related to a specific family line. This option is suitable for both personal reassurance and more formal requirements, depending on your needs.

Grandparentage DNA testing can be highly informative, though results may vary based on who is tested. When only one grandparent is available, results typically provide a strong probability of relatedness. When both paternal grandparents and the child’s mother are included, the probability of establishing paternity often reaches 99.9% or higher, offering a level of confidence comparable to traditional paternity testing.
