Grandparentage DNA Testing
What is DNA Grandparentage Testing?
Grandparentage Testing establishes a Maternal or Paternal relationships. In cases where a suspected Mother or Father are deceased, missing, or unavailable to participate in genetic testing, both of the Paternal or Maternal Grandparents can be tested in order to determine the likelihood of Grandparentage.
Is the Grandparent DNA Test Conclusive?
When the Child's genes do not match the Possible Grandparents' genes on at least two different gene sites, the test proves conclusively (it is certain) that the tested Grandparents are NOT the biological Grandparents. In this case, it is presumed that the Possible Father or Possible Mother is NOT in fact a biological parent. However, when the Possible Grandparent's alleles match the alleles of the Child, the probability of Grandparentage is determined.
In a case where both Grandparents are not available to contribute samples, a Family Reconstruction Test must take place, which can include any known biological family members of the Possible Father or Possible Mother.

Note: Family Reconstruction can potentially exclude with absolute certainty or demonstrate greater than 99.9% probability ONLY if a sufficient number of family members are tested.
Why Invest In A DNA Identifiers' Test?
DNA Identifiers' Grandparentage Tests are the most advanced, accurate, state of the art genetic test available today. Our results are obtained using strict chain of custody documentation and are notarized and guaranteed for accuracy. Using this advanced technology, the average probability of Fatherhood will be conclusive as either 0% (is not the Father) or greater than 99.99% (is the Father). This level of accuracy is over one million times greater than most State and Federal Government standards and is significantly better than tests performed by other laboratories.
DNA Identifiers offers both Court Admissible Legal Paternity Tests and Non-Legal Home Kits. If you need a Court Admissible Test, DNA Identifiers will make an appointment to meet you at a safe location of your choice, most likely your home or lawyer's office. This unique service will save you time, money, gas, travel expenses and the hassle of fighting traffic and driving long distances. Plus, all DNA samples are painlessly obtained using a cheek swab (special cotton swab), not a blood draw.
