Requirements for the grandparentage DNA test

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.

We suggest a grandparents test when clients need to establish the paternity of a child through the child’s paternal grandparents. We recommended testing both grandparents if available, as this will help obtain more conclusive results. As in all relationship testing, the sample of a common parent (normally the mother) is always recommended. The price of the grandparents test will change according to the number of people being tested.

Options for grandparentage analysis

  1. DNA analysis of single grandparent: this test requires DNA samples from just ONE of the grandparents. We do not offer single grandparents testing and suggest you contact us to discuss alternative tests in such cases.
  2. DNA analysis of both grandparents: We can only offer grandparent testing if we have samples from both grandparents. The mother’s sample should also be included if available.

In both types of tests the DNA profiles analysed are compared with that of the grandchild to establish a biological relationship. The mother’s samples are included to quickly eliminate her share of the DNA in the heredity process, which in turn leaves just the paternal half to test.

Test results

The cost of grandparentage test starts from as little as $299. Results are normally sent by email within 5-7 working days from when we receive the samples at the laboratory.

Test results are intended to provide a statistical likelihood that gives evidence to support the tested relationship in question. Providing additional parties to be tested (for example, a known parent’s sample) or performing direct relationship testing may provide additional evidence.

Note: We can only guarantee standard result turnaround time when testing takes place solely using oral swab samples. Using a discreet sample for your test may lead to an increase in turnaround time.
