At times grandparents are concerned that they might not be the actual grandparent of the child. They initiate this test simply to know the truth. A grandparent DNA test determines the biological relationship of a grandchild with the grandparents. Grandparent DNA testing is particularly useful when the alleged father is not available for testing.
In a grandparent DNA test, DNA samples are collected using buccal swabs (mouth swab) from the grandparent(s) and the grandchild. At the laboratory, the DNA is extracted from the cell and specific regions of the DNA (STRs) are amplified by a process known as PCR (polymerase chain reaction). The DNA profile (pattern) of the grandparent is then compared to the DNA profile (pattern) of the grandchild. A statistical analysis is performed to obtain a “grandparentage index”
- If you need DNA test results for a legal reason (court admissible ), at-home testing is not an option. For court-admissible results, you must call/email us to schedule appointment for sample collection at our location.
- If you do not have legal authority to act on behalf of a minor child, the burden is on you to obtain all necessary consents before submitting the minor child’s DNA for testing
