Grandparent Genes. DNA Testing.

A grandparent DNA test can establish the biological relationship between your child and an alleged grandparent, giving your children and their grandparents a chance to build what is one of the most vital and fulfilling relationships in their lives. Grandparent DNA testing can also be helpful in some paternity testing cases when the alleged father is not available.

When testing both grandparents, IDENTIGENE routinely provides result probabilities greater than 99.99%. DNA testing with only one grandparent can also produce accurate results.

Legal & Immigration DNA Testing

"Legal" relationship tests, or DNA testing for legal purposes, like legal paternity tests, require accurate test results as well as proof of identity for each person participating in the DNA test. For legal cases, IDENTIGENE tracks your DNA samples from the time they are collected at one of our DNA collection sites until the time they arrive in our DNA paternity testing lab. Following this chain-of-custody procedure outlined in the accreditation guidelines offers proof of the relationship (or non-relationship) as well as proof of identity to a judge, social worker, or other government official.
