Grandparent DNA Testing

Grandparent DNA Testing

Determine the Paternity of a Child by Grandparent DNA Testing

A grandparent DNA Test helps establish the biological relationship of a child with his or her grandparents. This test indirectly determines the family relationship of a child in cases where father is not available for paternity DNA test (mostly father is deceased or missing).

Grandparentage DNA Test

How a grandparent DNA Test works?

At times grandparents are concerned that they might not be the actual grandparent of the child. They initiate this test simply to know the truth. A grandparent DNA test determines the biological relationship of a grandchild with the grandparents. Grandparent DNA testing is particularly useful when the alleged father is not available for testing.

In a grandparent DNA test, DNA samples are collected using buccal swabs (mouth swab) from the grandparent(s) and the grandchild. At the laboratory, the DNA is extracted from the cell and specific regions of the DNA (STRs) are amplified by a process known as PCR (polymerase chain reaction). The DNA profile (pattern) of the grandparent is then compared to the DNA profile (pattern) of the grandchild. A statistical analysis is performed to obtain a “grandparentage index”

  • If you need DNA test results for a legal reason (court admissible ), at-home testing is not an option. For court-admissible results, you must call/email us to schedule appointment for sample collection at our location.
  • If you do not have legal authority to act on behalf of a minor child, the burden is on you to obtain all necessary consents before submitting the minor child’s DNA for testing

A grandparent DNA test is done by recreating the alleged father’s DNA profile by using his parents DNA profiles Using the DNA profile that has been recreated it is compared to the child’s DNA profile to calculate the statistical probability of the tested grandparents being the biological grandparents of the child.
