Legal vs. Personal DNA Testing Options

There are several options in types of DNA testing available, but most of them boil down to results being delivered in a “Legal” or “Non-Legal” version. Costs of these versions differ greatly, so it’s important for the client to understand what they are buying.

Non-Legal Personal DNA Paternity Tests

Personal DNA paternity tests generally are less expensive than Legal DNA tests. Keep in mind a few pieces of information about personal DNA tests:

• Results from a personal DNA test cannot later be converted into a legal DNA test
• Results from a personal DNA test are not admissible in court
• Collections can be done very discreetly and the name implies the most obvious reason for the test… for personal knowledge and peace of mind

Legal DNA Paternity Tests

Legal DNA paternity tests are often significantly more expensive than personal DNA paternity tests, but for good reason. There is usually important benefits at stake that are contingent on the results of the test. (Check out our earlier post listing several reasons where DNA testing can be very useful).

The actual sample collection procedures for a Legal DNA paternity test are exactly the same as those for a Personal DNA paternity test. However, in a Legal DNA paternity test a strict chain of custody process is followed. Because the collection is done in a controlled environment, test results are admissible in a court of law. The typical chain of custody process is outlined here:

• Each patient (typically the alleged father, mother, and child) are formally identified to the individual conducting the sample collection. This typically involves producing government-issued photo IDs, witnessing signatures, and taking photos of any minor children.
• DNA specimens are collected, labeled and packaged individually in the presence of the patients.
• Specimens are kept in a controlled place and not left unattended. The Collector securely packages the specimens for shipment to the DNA lab.
• The DNA lab acknowledges receipt of specimens and all documentation become business records.

So, when you are shopping for the right DNA testing service for your personal situation, be sure to understand how the test results will need to be used.
