Non-exclusion (inclusion)

Definition

A finding that the alleged parent's blood group profile is compatible with parentage. Non-exclusion does not prove parentage: it means only that the person cannot be eliminated on serological grounds, and many unrelated individuals may share the same compatible profile.
