Test ID PCPMX Phencyclidine (PCP) Confirmation, Chain of Custody, Meconium

Useful For

Detection of in utero drug exposure up to 5 months before birth

 

Chain of custody is required whenever the results of testing could be used in a court of law. Its purpose is to protect the rights of the individual contributing the specimen by demonstrating that it was under the control of personnel involved with testing the specimen at all times; this control implies that the opportunity for specimen tampering would be limited. Since the evidence of illicit drug use during pregnancy can be cause for separating the baby from the mother, a complete chain of custody ensures that the test results are appropriate for legal proceedings.
