Two different types of Grandparent Testing

Single Grandparent DNA Analysis: This DNA test includes ONE grandparent, 1 grandchild, and parent (optional, but strongly suggested). The conclusive range for DNA results are either >90% (inclusion) or <15% (exclusion) probabilities. However, results may vary between 1% and 99% accuracy.

Duo Grandparent DNA Analysis: This DNA test includes BOTH grandparents, 1 child, and parent optional, but strongly suggested. For the most accurate results in a grand-parentage analysis it is best to include both the alleged grandparents and the child. When both alleged grandparents are included the DNA results can indicate greater than 99% (for inclusions) or 0% (for exclusions) probability of the Grand-parentage relationship.
