Grandparentage DNA Testing is a powerful tool for determining genetic relationships. With this type of testing, it is possible to determine with accuracy whether or not two individuals are related through bloodlines. It is often used when the father or mother of a child is not available for testing, or if the family history has been incompletely documented.

Non-Legal Grandparentage Test

With our non-legal Grandparentage Test, you can collect DNA samples privately and confidentially in your own home. When all testing procedures are carefully followed, the results of the test will be as accurate as with any other collection procedure. However, the information obtained cannot be used in court proceedings because the process does not follow approved chain of custody requirements.

Legal Grandparentage Test

Legal Grandparentage Testing follows the strict requirements of chain of custody, and therefore can be admitted as evidence in court. If the purpose of testing is to conclusively determine genetic relationships for custody, child support or inheritance in a legal or government proceeding, our binding legal testing protocol is the appropriate choice.

How accurate is grandparentage DNA testing?

The accuracy of grandparentage DNA testing can vary depending on a number of factors, such as the number of genetic markers that are tested, the quality of the DNA samples, and the relationship between the grandparents and the child. Generally, the more genetic markers that are tested, the more accurate the results will be. Most reputable DNA testing companies claim an accuracy rate of 90-99% for grandparentage testing.

How is the DNA sample collected for grandparentage testing?
The DNA sample for the grandparents and the child can be collected using a simple cheek swab, which involves swabbing the inside of the mouth with a cotton swab to collect cells for testing. The samples can then be sent to a DNA testing lab for analysis.
How long does it take to get the results of a grandparentage DNA test?
The turnaround time for grandparentage DNA testing can vary depending on the DNA testing company and the type of test that is ordered. Some companies offer expedited testing for an additional fee, which can reduce the turnaround time to a few days. However, in general, it can take several weeks to receive the results of a grandparentage DNA test.
How much does grandparentage DNA testing cost?
The cost of grandparentage DNA testing can vary depending on the DNA testing company, the number of genetic markers that are tested, and any additional services that are ordered (such as expedited testing or legal documentation). Generally, grandparentage testing is more expensive than paternity testing, with prices ranging from several hundred to several thousand dollars.
Can grandparentage DNA testing be used for legal purposes?
Yes, grandparentage DNA testing can be used for legal purposes such as establishing child support, custody, or immigration cases. However, in order to be admissible in court, the testing must be conducted by an accredited laboratory and follow certain chain-of-custody procedures to ensure the accuracy and reliability of the results.
What is the process for getting a grandparentage DNA test for legal purposes?
If you need a grandparentage DNA test for legal purposes, such as for immigration or custody cases, you will need to work with a DNA testing company that offers legal testing services. The testing company will typically provide you with a legal testing kit that includes everything you need to collect the DNA samples and send them to the lab, including instructions for sample collection, chain-of-custody documentation, and a prepaid shipping label to send the samples back to the lab.

Once the lab receives the samples, they will analyze the DNA and produce a report that includes the test results. If the test results indicate that the grandparents are biologically related to the child, this can be used as evidence in a legal case. It’s important to note that the rules and requirements for using DNA testing in legal cases can vary depending on the jurisdiction and the type of case, so it’s important to consult with an attorney or legal expert to understand how DNA testing can be used in your particular case.

Can grandparentage DNA testing be used to establish paternity?
While grandparentage DNA testing cannot directly establish paternity, it can be used to provide indirect evidence of paternity in cases where the alleged father is not available for testing. For example, if the grandparents on the alleged father’s side are tested and found to be biologically related to the child, this can provide strong evidence that the alleged father is also biologically related to the child. However, it’s important to note that the accuracy of this type of testing is lower than direct paternity testing, so it may not be sufficient to establish paternity in all cases.
