The GeneTree DNA Duo Grandparentage (Additional) Lab Test Kit is for additional grandchildren included in the Duo Grandparent Test.
This product is a test option for the GeneTree DNA Duo Grandparentage tests. The best way to understand how this option works is best explained by the following examples:
Situation #1.) If both grandparents and two alleged grandchildren are being tested, then you should order one GeneTree DNA Duo Grandparentage Test and one GeneTree DNA Duo Grandparentage (additional alleged grandparent) test option.
Situation #2.) If both grandparents and three alleged grandchildren are being tested, then you should order one GeneTree DNA Duo Grandparentage Test and two GeneTree DNA Duo Grandparentage (additional alleged grandparent) test options.
