Understanding the differences
Private vs. Legal DNA Testing
Private DNA testing is a convenient and affordable way to establish biological relationships, such as paternity, sibling, or grandparent connections, in a personal and private setting.
With private DNA testing, you can collect your DNA samples using a simple at-home cheek swab kit and send them directly to the laboratory for analysis.
Private DNA testing offers the same level of precision as legal DNA testing, but the process does not require strict chain of custody procedures or sample collection by an unbiased third party. This makes it a great option for those who want to maintain privacy and control over the testing process.
It’s important to keep in mind that the results of a private DNA test are not legally admissible in court. If you need DNA testing for legal purposes, you’ll need to choose a legal DNA testing option.
Legal DNA testing is a highly regulated procedure that is used to establish paternity or other biological relationships for legal purposes.
Legal DNA test results are commonly used in child custody and support cases, inheritance disputes, immigration cases, and other legal proceedings where the biological relationship between individuals needs to be established.
Legal DNA tests require the DNA samples to be collected by an unbiased third party following a strict chain of custody protocol. You can arrange for sample collection and witnessing services yourself, or we can assist you in setting up appointments at one of our locations.
