After the DNA samples are collected, the samples are sent to a laboratory for DNA paternity testing. The results are generally available within a week.
DNA testing laboratories, such as the DNA Diagnostics Center, are accredited by the American Association of Blood Banks and perform DNA paternity tests using a Chain of Custody documentation process. The Chain of Custody process is the standard that satisfies the legal requirements for test results to be admissible in court.
The results of DNA paternity tests done by an accredited laboratory can include the father of a child with 99.99% accuracy or exclude a potential father completely.
