A grandparent DNA test determines whether a couple could be the biological grandparent of a child. It is anindirect way to determine family relationships when an alleged father is not available for a paternity test. Grandparent test results may be used as proof in Social Security benefit and other inheritance claims as well as in some Immigration cases.
DNA samples are collected by a painless buccal (cheek) swab method. Results are reported typically within 3-5 working days.
