Grandparent DNA Testing is especially useful when the alleged parents of a child are not available for paternity or maternity testing. Testing the alleged grandparents of the child in question can provide an answer. If the alleged grandparents are the biological grandparents of the child in question, then they are likely to possess common genetic markers. Unlike DNA paternity or maternity tests, which will always provide a conclusive result, Grandparent DNA Testing will reveal a probability of relationship, which may range from <1% to >99%. Who needs to test? Single Grandparent DNA Test   This type of DNA test includes one alleged grandparent and grandchild. Dual Grandparent DNA Testing   Includes two alleged grandparents (paternal or maternal) and grandchild.

For the most accurate results in Grandparent testing, it is best to include both of the alleged grandparents and the grandchild. When both grandparents are included in the DNA test, results may yield greater accuracies. As a general rule, results may vary between <1% and >99% accuracy.
