Grandparent

A grandparentage DNA test is used to establish a genetic family relationship between a possible grandparent and grandchild or to establish paternity if the child's alleged father is not available for testing.

LEGAL TESTS

When should I use a legal grandparent test?

A grandparent test establishes whether a child is likely to be related to an assumed grandparent or grandparents.  Such tests can be used to establish a family relationship when the child’s alleged father is not available for testing. The alleged father’s genetic profile can be reconstructed by evaluating the DNA samples obtained from his biological parents. In order to obtain the best results, the mother of the child and both alleged grandparents should be submitted for testing. If the testing is to verify the motherhood of a child, please request a callback for additional information.

What type of sample is collected in a legal test?

The most common sample type is a buccal swab. This sample is collected using a cotton swab that is gently rubbed on the inside of your cheek. Blood samples are also acceptable.

AT-HOME TESTS (NON-LEGAL)

At-home DNA tests are commonly called non-legal tests. DNA samples for at-home tests are collected by individuals in the privacy of their own home. They provide the same information as a legal DNA test, but they are not intended for use in a court of law. If there is a possibility that the results might be needed for legal purposes, a legal test should be performed.
