How grandparent DNA testing works when the father is not available.
A typical scenario
The father is unavailable, and his parents want to confirm their relationship with a grandchild.
Who should participate
Both paternal grandparents give the strongest analysis. Where only one grandparent is available, the mother should also participate.
How results are expressed
Results are a statistical likelihood of the relationship.
Collection
Standard cheek swabs, collected at an appointment or with an approved kit.
