External Collections may be performed by a professional collection service, attorney's office or any appropriate location where chain of custody may be established. It is the responsibility of the requesting agency to arrange for acceptable collections. Forensic specimens are analyzed under strict forensically acceptable criteria and a chain of custody is maintained. In addition, results are critiqued by forensic chemists and the Laboratory Director to ensure accurate and adequate analyses have been performed. Testing will only be performed on a C.O.D. basis.
Testing consists of appropriate screen and confirmation of any positive.
