Grandparent DNA Testing
When an alleged father (or mother) is not directly able to be tested, at least one of the suspected father’s (or mother’s) biological parents can perform a DNA grandparent test to help determine if he or she is the true father or mother of a child.
Biological parents equally contribute 50% to their child’s DNA, so that one-half of his DNA comes from each parent. When that child becomes a parent, they in turn contribute half of their DNA to their child. Therefore, 25% of the grandchild’s DNA comes from each grandparent, through their biological child.
How accurate is our Grandparent DNA test?
We guarantee we provide the most accurate DNA Grandparent test available.
Grandparent DNA testing is based on the statistical probability that two or more people are related by bloodlines as grandparent and grandchild. The industry standard for testing of this type compares 16 alleles to attempt to arrive at the conclusion if a grandparent/grandchild relationship exists.
The challenges and limitations with this approach is that when using so little genetic material, it is very difficult to arrive at a conclusive result because a grandparent only shares up to 25% of the same DNA with their suspected grandchild. All humanity shares 99.9% of the same DNA, which means that only .10% can be used to determine the answer as to whether or not a grandparent/grandchild relationship exists.
When only 16 markers are being considered, there is a very good possibility that an inconclusive result will be reported. Even worse, a false negative or false positive is also a potential outcome. Bio-Gene DNA holds the position that there are just not enough markers tested in a standard test to feel confident about the results.
Bio-Gene DNA uses up to 50% more alleles than other companies to perform the DNA testing. The DNA sample of the mother can be included at no additional charge.
More markers tested means a more accurate result. It’s a scientific fact.
There are times or reasons that the other grandparent, or the mother, is not available for the grandparent testing. In these cases our testing lab makes a mathematical and scientific adjustment in the testing process which allows for only one grandparent and one grandchild being tested with results that are accurate, clear, and understandable in almost every case we handle.
Do you need to test someone who lives in another location? We can do that!
We can send DNA collection kits to multiple addresses for the same test. When ordering, just select how many kits you need (one per address is suggested). List the names and addresses we are shipping to on the order form. Each test kit will be coded with your case number and matched with both the name of the person and your unique case number in lab. Testing will begin once all samples have been received.
Fast results. One business day processing is available!
We know how important these answers are to you, and we want to help you learn the truth as quickly as possible. Rush processing is an optional service with results delivered in ONE business day for an additional $100.00.
Alternative samples are not eligible for one day processing as a viability test must be performed prior to testing on any samples other than a mouth swab or blood card.
Grandparent DNA testing results
Results are provided in a PDF file through a secure login to the person ordering the test once they are ready. Testing results are always kept confidential and your DNA is never used for any other research purpose or provided to any other person, company, or government.

Often Asked Questions About
If both grandparents are available to test, you may wish to consider that option, as the testing results are no different than a paternity test using the suspected biological father.
When both grandparents, or the mother, is not available our testing laboratory automatically adjusts the testing process to account for one grandparent and one child.
If you are needing a legal DNA test then the custodial parent or legal guardian will need to give written consent.

How to take a home Grandparent DNA test
The most accurate method of obtaining your DNA is to use a buccal swab, which is very similar to a “Q-tip” cotton swab. The swabs are rubbed on the inner cheeks of the mouth of those being tested. We provide all the materials needed for the DNA collection in our Bio-Gene DNA Test Kit.
However, we know that sometimes it is not possible to obtain a buccal swab sample. We are often able to test discreet alternative DNA samples. To learn more about non-standard, alternative DNA samples that we can test, CLICK HERE.
