How to Read a DNA Test Report
◉ Limitations of DNA Sibling Testing and Indications for Use
The grandparentage test is not as powerful as the paternity test. The paternity test will always give an absolutely conclusive result regarding paternity. Whenever the alleged father is available for testing, the paternity test is always the recommended test as it is the most powerful and conclusive test. However, in cases where the alleged father is not available for testing and there is no other option but to test the grandparents, the DNA Grandparentage test will provide you with the likelihood that an alleged grandparent is the true biological grandparent of a grandchild.
◉ Understanding the DNA Grandparentage Test Report
The DNA sibling test report will provide you with a grandparentage index. The grandparentage index will provide the likelihood that a tested grandparent is the true biological grandparent of a grandchild. If both the grandfather and the grandmother are available for testing, the report will show whether the child can be excluded at the biological grandchild of the grandparents.

FAQs
How does a DNA Grandparentage Test work?
Every person has two copies of each gene. One copy comes from the mother and the other copy comes from the father. Thus, one half of the genetic material in our body is inherited directly from each of our two parents. Likewise, our parents inherited their DNA from their parents (our grandparents). When a DNA grandparentage test is performed, the DNA laboratory examines the DNA of the grandparent and the grandchild and then compares them to generate a grandparentage index. If the alleged grandparent is the true biological grandparent of a grandchild, then the grandparentage index is expected to be greater than 1.0. If both the grandmother and the grandfather are available for testing, an additional analyis called a “reconstruction test” is performed to see if the grandchild can be excluded as the biological grandchild of the grandparents. If the grandchild is excluded, then it would conclusively conclude that the grandparent pair are not the true biological grandparents of the grandchild.
The grandparentage test is a statistical analysis based on the pattern of expression of genetic material in the individuals compared. The grandparentage test is not as powerful as the paternity test and should only be considered if the alleged father is not available for testing. If the biological mother of the grandchild is available for testing, adding the mother to the DNA grandparentage test can help to increase the discrimination power of the test.

What is the difference between the Legal Test and the Private Test?
Both the Legal and Private tests are equally accurate and both will provide absolutely conclusive results. If you choose the private test, a home kit will be sent to you so that you can collect the samples discreetly in private. If you choose the Legal Test, the collection must be done by an unbiased individual (doctor, lawyer, notary, etc.) and all individuals attending the collection appointment must bringa passport photo, picture identification, and they will be fingerprinted during the sample collection appointment. If you do not need to use the results in court, then the private option will provide the same conclusive results as the legal test and can be done discreetly.
What if the parties to be tested live in different cities?
If the parties to be tested living different cities or different countries, the kit can be split and sent to each individual separately. The kits are indivdividually barcode labelled so once the samples arrive back at the laboratory, they will be sted together. To order a split kit, please write the following into the comments box of the online order form when you place the order “Please split kit. Please send grandmother’s portion of the kit to: (grandmother’s name and address), and please send the grandchild’s portion of the kit to: (grandchild’s name and address).”
What are the CODIS Loci?
CODIS stands for Combined DNA Index System. The CODIS loci are the loci which are approved by the FBI and other recognized standardization bodies worldwide for databasing and genetic profiling. At International Paternity Labs, 13 out of the 16 loci which we test are CODIS loci. As such, the profile obtained from each test far exceeds the current recognized standards.
