CUSTOMER SERVICE AWARD WINNER

We offer two types of grandparentage tests

A grandparents test allows us to the DNA of alleged father’s parents and tell you whether these individuals are genetically related to their grandchild/children and thus, whether the children tested are children of their alleged, biological father.

  • Duo grandparentage DNA test: This is the ideal test as it allows us to reconstruct both grandparents genetic profiles and have a fuller insight of genetic inheritance patterns in relation to the child.
  • Single grandparentage test:  Grandparentage DNA testing can be done with a single grandparent albeit with less accuracy. In a single grandparents DNA test we strongly recommend addition of the mother’s sample.

Note that if the test involves alleged grandfather and male grandchild, we can confirm their biological relationship with a Y chromosome test.

You results will show the probability of a biological grandparentage which will be expressed as a percentage.

Due to New York State Department of Health regulations, we cannot offer any peace of mind paternity or relationship tests to New York residents. However, we can offer legal paternity and relationship tests in New York. Contact us or click here for more information.
