DNA Solutions Grand-Parentage test will give you a definite answer on whether or not you are biologically related to your grandson/granddaughter.
DNA Solutions uses the latest techniques to give you the most accurate result in the quickest turnaround time, only 8 business days. To obtain the highest statistical result we recommend testing the grandson/granddaughter’s sample and, both grandparents’ samples as well as the mother’s sample, if possible. Testing these samples you will be aiming to the highest statistical and most accurate result.
NOTE: To have the Mother’s DNA sample (from both or either sibling) drastically increases the accuracy of the test and is included in the testing costs.
