Paternal grandparents can help establish paternity legally or for peace of mind when the alleged father is unavailable for testing. In this post, we outline testing options to determine a biological relationship with grandparents if the alleged father is unavailable. Millions of children in the U.S. cannot establish paternity due to the unavailability of the alleged father for testing.


What is a Grandparent DNA Test?

A Grandparent DNA Test determines the biological relationship between grandparents and their grandchild or grandchildren through genetic analysis. The child’s mother’s participation increases the efficiency of the analysis.

Our partner AABB-accredited laboratory performs all legal DNA Grandparent testing services. Family courts, birth certificate offices, and immigration agencies nationwide recognize your results due to the lab’s accreditation

All DNA samples undergo testing and analysis between 18-24 genetic markers or loci for accuracy.

Why perform a Grandparentage Test?

A DNA grandparent test is performed when alleged father of a child is unable to participate in paternity testing process. Testing the one or both paternal grandparents can help to prove if a biological relationship exists.

Some of the common circumstances to perform this testing options are:

  1. Adding a deceased father name to child’s birth certificate
  2. Social Security benefits
  3. Immigrant visa – Help to prove biological relatedness when the evidence submitted is insufficient.
  4. Inheritance

Method of DNA Specimen Collection

The preferred DNA sample collection method for DNA testing is by cheek swab. When cheek swabs are used to collect epithelial cells inside of the mouth when brushed against the cheek using a long cotton swab on the left and right side.

Alternative Specimens

Certain situations may require the use of alternative samples for DNA testing analysis. Consider the following options:

  • Hair follicles can provide a viable source of DNA when traditional samples are unavailable.
  • Toothbrush bristles may retain cells that contain DNA, making them useful for analysis.
  • Bone (femur) can be extracted for DNA testing, especially in cases involving skeletal remains.
  • Ear wax can serve as a sample, as it may contain cellular material.
  • Mucus on a handkerchief or Kleenex

Results Accuracy

Grandparent DNA testing is generally considered to be very accurate.

This testing option can provide a probability of grandparentage in the high 90% range, often 99% or higher. If both of the alleged grandparents are tested and are proven to be biologically related to the grandchild.

To increase accuracy, testing both paternal grandparents and the child’s mother is recommended, which can produce a 99.9% or higher probability similar to a paternity test.
