How It Works

Legal DNA test – when needing a DNA test for paternity, child custody or any court ordered purpose a legal DNA test must be performed at a testing center, the child/children and the alleged father will be scheduled to go to one of our many testing centers nationwide with appropriate documentation, identification, and the test will be performed by a qualified DNA test collector who will then send the specimen to a certified AABB laboratory. Results will be available in approximately 10 days after the laboratory receives the specimen.

Non-legal DNA test -this test is performed for informational purposes only, a DNA certified test kit will be sent to the purchaser via regular mail or overnight delivery. The kit will include clear instructions of how to perform the DNA test, the purchaser will utilize an oral fluid swab for the child/children and alleged father. upon completion the specimen will be placed in a prepaid delivery envelope and sent to our AABB certified laboratory. Results will be available in approximately 10 days after the specimens are received at the laboratory. Please remember the non-legal DNA test cannot be used in a court of law or for any legal purpose.
