When visiting a Patient Service Center, individuals should bring the following information with them:

  • The Laboratory Chain of Custody Form (COC) provided to you by Global HR Research. Please be certain the laboratory name on the COC matches the PSC you are going to.
  • A photo ID for urine drug screens (e.g., driver's license, employee identification badge).

Minors MUST be accompanied by their parent or legal guardian.

  • If you are bringing a minor to a Patient Service Center and you are not the legal guardian, you will need to bring a notarized statement signed by a parent or legal guardian authorizing you to give permission for the collection and billing of the tests ordered by the minor's physician.
