Product Information

Accurate Testing with Legal Chain of Custody Procedures. Appointment Only.

Overview of the Test

The Urine Drug Test WITH Chain of Custody is a professional and legally compliant test for detecting multiple drugs, including amphetamines, benzodiazepines, and cannabinoids. This test ensures that every step of the sample collection, handling, and analysis adheres to strict legal standards.  It is the type of test requested by employers (e.g. TfL) and courts. This combination of drugs is often requested for working in the USA and Sweden for visa or work purposes. Negative results are available within 2 working days*, while positive results require confirmatory testing, adding an additional 5 working days.

Why It Would Be Used

This test is ideal for individuals or organisations requiring drug testing with legal traceability:

  • Legal Purposes: Provides admissible evidence for court cases or legal disputes.
  • Workplace Testing: Ensures compliance with workplace policies and regulatory standards (e.g. TfL)
  • Personal Monitoring: Offers legally valid proof of recent substance use.

Our chain of custody process ensures every sample is tracked and verified throughout the testing process.
