Find out if you’re the biological grandmother or grandfather.

This at-home DNA grandparent test kit is ideal for determining the likelihood of a biological grandparent-grandchild relationship when the parent(s) in question cannot be tested directly. With this easy-to-use home kit, you can collect a mouth swab quickly and discreetly in the privacy of your own home and send it to our laboratory for analysis. Your test results will be available for download from your secure online account within 1-2 business days of receipt at the lab.

Either the grandmother, or the grandfather, or both, can take the DNA Grandparent Test to investigate whether a genetic relationship exists between the alleged grandparent and grandchild. If the parent(s) in question are available for testing, we recommend taking the DNA Paternity Test or DNA Maternity Test over the grandparent test.


DNA Grandparent Test Methods

During a DNA Grandparent Test, a buccal (mouth) swab sample is collected from the child and the potential grandmother or grandfather. The sample contains cells, and most of the cells in our body contain a full set of genetic information in the form of DNA (deoxyribonucleic acid). A person’s DNA represents a “genetic blueprint” and, like a fingerprint, it is unique to each individual.

At the laboratory, the DNA is extracted from the cell and specific regions of the DNA are amplified by a process known as PCR (polymerase chain reaction). Our test analyzes 16 to 27 of these specific regions, called short tandem repeats (STRs). STRs are regions of DNA in which a short DNA sequence is repeated multiple times. They are found throughout the genome and are highly variable, providing an accurate way to confirm or refute biological relationships.

Frequently Asked Questions

Here are the answers to the most frequently asked questions about this test. Please feel free to contact us if you have any other questions.

Absolutely. If the individuals participating in the test are in different locations, we can send parts of the DNA test kit to different cities. During checkout, please enter “Please split kit” in the “Additional Notes” comments box and let us know where to send each component. For example, you can say “Send the Grandmother/Grandfather kit to [Name, Address]” and “Send the Grandchild kit to [Name, Address]”. Each component is individually barcoded, ensuring that your samples will be tested together once they arrive at the laboratory.

If you need DNA results for legal purposes, such as court proceedings, child custody or support, or inheritance claims, you will need to order the Legal DNA Grandparent Test. Legal DNA Grandparent Tests require a chain of custody procedure to be admissible in court. This involves having the DNA samples collected by a neutral third party, proper identification of the test participants, and the samples being directly sent to the testing laboratory. Legal DNA Grandparent Testing is available in the US, Canada and UK.

No, there are no age restrictions for participating in a DNA grandparent test. This test is suitable for individuals of any age, including newborns. For minors, a legal guardian’s consent is required.

No. The test kits do not have an expiration date and can be stored indefinitely before sample collection. However, once a sample is collected, it’s best to return the kit to our laboratory for testing within 3 months.

DNA collection is a simple, safe, and painless process. It involves gently rubbing a brush (buccal swab) inside the mouth against the cheek for 15 seconds.

Your results will show two numbers (alleles) that indicate the number of repeats that you received from each parent at each STR. You may have two identical alleles at a marker, or you may have two different alleles. These allele numbers are compared between the alleged grandparent and grandchild, and a statistical analysis is performed based on the match type typically expected for true biologically related grandparent/grandchild pairs.

True biologically related grandparent/grandchild pairs are expected to have a grandparentage index value greater than 1.0. The greater the grandparentage index value over 1.0, the higher the likelihood that the two individuals are biologically related as grandparent/grandchild.

Individuals who are not grandparent/grandchild are expected to have a grandparentage index value that is less than 1.0. The lower the grandparentage index below 1.0, the lower the likelihood that the two individuals are biologically related as grandparent/grandchild.
