The DNA Grandparentage test provides the likelihood that and alleged grandparent is the true biological grandparent of a grandchild. The grandparentage test should be chosen only if the alleged parent is not available for testing because the grandparentage test is not as powerful as the parentage test. The parentage test will always give an absolutely conclusive result regarding paternity or maternity. Whenever the alleged parents in question are available for testing, the parentage test is always the recommended test as it is the most powerful and conclusive test. The DNA Grandparentage test should be chosen only when the parent in question is unavailable for testing.
After ordering this test, a buccal swab collection kit will be sent to you. Follow the instructions provided in the kit to collect a fast and simple mouth swab sample from the alleged grandparent(s) and grandchild using the swabs provided in the kit. The sample collection process is simple and painless and takes only a few seconds to complete. After sample collection, return the sample to the laboratory for testing using the return package included in the kit. Once the laboratory receives your samples, testing begins immediately and the results are available within 3 to 5 business days. The full genetic report and results document will be sent to you by mail and email.
If the individuals to be tested live in different addresses, the kit can be split and sent separately to each address. To request a split kit, please write "Split kit please" in the comments box of the order form. Please also indicate the name and shipping address for the grandparent's portion of the kit, and the name and shipping address for the grandchild's portion of the kit.
The DNA Grandparentage test examines the Autosomal STR markers in the grandparent and the grandchild and then compares them to generate a grandparentage index. If the grandparentage index value is greater than 1.00, it would indicate that the alleged grandparent are more likely to be the true grandparent of the grandchild. If the grandparentage index value is below 1.00, it would indicate that the individuals are more likely not to be related. The higher the sibling index value is above 1.00, the greater the likelihood that the grandparent is the true biological grandparent of the grandchild.
If both grandparents are available for testing, a further reconstruction test is performed. The reconstruction test combines the genetic profile of both grandparents and can conclusively exclude a grandchild from being related if the markers in the child do not match the reconstructed profile generated from the alleged grandmother and alleged grandfather.
Yes, including the mother of the child in the Grandparentage test can increase the power of the test.
No, the sample can be collected from individuals at any age, even newborns.
The unused kit will remain stable indefinitely at room temperature so you can use it at any time after you receive it. Once you open the kit and collect the samples, the sample will remain stable for at least 3 months after sample collection.
The turnaround time for testing is 3 to 5 business days after your samples arrive. At the time that you place the order, you can choose to receive your results by email, mail or both. If you had chosen email as the method for receiving your results, your results will be sent to you by email the same day that testing is completed.
