In cases where the alleged father is deceased or unknown, the paternal grandparents can be tested to determine the likelihood they are the child's true paternal grandparents.

How certain are the results when the tested grandparents are NOT true paternal grandparents?
The DNA Test for Grandparentage proves conclusively that the tested individuals are NOT the true paternal grandparents of the child. In such cases, the tested grandparents' genes do not match the child's genes on at least two different genes. The probability of grandparentage is 0%, and we are 100% certain that they are NOT the child's paternal grandparents.

How certain are the results when the tested individuals ARE true paternal grandparents?
The average probability of grandparentage for the GENETICA DNA Test™ is far in excess of 99.9%. We guarantee greater than 99.9% probability of grandparentage in all tests (or, we prove that the tested individuals are not true grandparents).
