About grandparentage DNA testing

A grandparentage DNA test is useful in cases when grandparents have a doubt about the parentage of their suppose grandchild. This type of DNA testing is useful when the alleged father is not available for testing. The alleged father’s parents can be used for testing in order to determine if they are biological grandparents of the child. The cost of the grandparentage DNA test is $399.

Types of grandparent testing

Duo grandparent DNA analysis: In this test, both the grandfather and grandmother’s DNA samples are provided for the test. Having both the samples of the paternal grandparents can help reconstruct the alleged father’s DNA profile. Having the mother’s DNA sample helps to get a more accurate result.

Single grandparent DNA analysis: This test is done when only a single grandparent is available for testing but does only in rare cases provide a conclusive result. For this reason, EasyDNA offers grandparent testing only if both grandmother and grandfather are available for the test. If only one grandparent is available, we suggest you contact us to discuss other testing options.

Important Notes

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.

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.

We strongly suggest including the sample of a known parent to provide stronger results

Y chromosome testing

If the test participants are male (grandfather and grandson) EasyDNA recommends a Y chromosome test, that can establish whether the male participants share the same parental line. Read more about Y chromosome testing.
