The chain of custody is what makes paternity test results legally accepted in courts and other government facilities.
The tested parties are properly identified when their samples are collected along with a picture taken of each party tested. The samples are collected by a third party, someone who has no personal interest in the outcome of the test.
The samples are tamper-taped, securely packaged at the collection site, and carefully inspected upon receipt by our laboratory department for any evidence of tampering.
