The DNA Grandparent Test is an easy, at-home DNA test kit used to determine whether an alleged grandparent is the true biological grandparent of a potential grandchild.
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, 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.
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 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.
What if the parties to be tested live in different cities, can you split the kit?
Yes, the kit can be split and the sample collection components sent to each address separately. The collection components are individually barcoded and will be tested together once the samples arrive at the laboratory. To order a split kit, write "Please split kit" in the Order notes box and indicate the name and address for each component.
Is there an age limit?
No. Any of the DNA tests can be performed on individuals of any age, even newborns. If the patient is a minor, the legal guardian must sign the DNA testing consent form.
How are the test kits stored?
All test kits are stored at room temperature before and after sample collection.
Do the test kits expire?
No. Test kits can be stored indefinitely prior to sample collection. Test kits should be returned for testing within 3 months after sample collection.
How is the DNA sample collected?
DNA is collected by rubbing a brush gently inside the mouth against the cheek for 15 seconds. The collection is safe and painless.
