Recent research comparing urine and oral fluid drug testing also found that urine testing remains significantly more effective at detecting drug use in workplace settings.
Why Speed Matters: The 2-Hour With-Cause Call-Out
When safety is on the line, response time is critical. Our 2-hour with-cause testing call-out service ensures that post-incident and suspicion-based testing is conducted before substances leave the system, reducing the risk of undetected drug use. A quick response can mean the difference between a safe workplace and a costly incident.
Ensuring Integrity: Chain of Custody Protocols
At Randox Testing Services, every sample is collected, processed, and transported with full chain of custody compliance to maintain accuracy, security, and legal defensibility.
Our Chain of Custody Process Includes:
- – Barcode-Linked Forms – Each sample is matched to documentation, ensuring full traceability.
- – Donor & Collector Signatures – Confirming the authenticity of every test.
- – Tamper-Evident Seals – Protecting samples from interference.
- – Secure Packaging & Transport – Ensuring sample integrity in transit.
