most accurate grandparent dna test
When an alleged father is not directly able to be tested, at least one of the suspected father’s biological parents can perform a DNA grandparent test to help determine if he is the true father of a child.
We guarantee we provide the most accurate DNA Grandparent test available.
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.
Using the most advanced methods for DNA testing, our AABB accredited testing laboratories are able to deliver accurate results every time, even when only one grandparent is available to test.
Commonly asked questions about grandparent testing
If both grandparents are not available, then we suggest using the mother of the child if possible to eliminate her DNA.
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.
In all cases we test over 50% more genetic material which allows for more accurate reporting of the suspected relationship. The results you will receive are 100% accurate and are based directly on the genetic profiles generated from the DNA samples you submit.
If you are needing a legal DNA test then the custodial parent or legal guardian will need to give written consent.
How accurate is our Grandparent DNA test?
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 100% accurate results, based on the genetic profiles obtained.

Bio-Gene DNA offers TWO options for collecting your DNA samples when you order.
Purchase a Bio-Gene DNA Test Kit.
This kit includes collection materials for up to 3 people, detailed instructions and a prepaid return mailer. Each kit ordered is sent via USPS Priority Mail with 2-3 day delivery. A tracking number will always be provided for your kit.
Cost: $9.95 each.
Using cotton swabs (“Q-tips”) you collect your DNA samples. Upon ordering you will be emailed a case number, detailed instructions, and the mailing address to send your samples to. To learn more about this option, please click here.

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.
