Drug Testing Process


1. Specimen Collection

The DOT collection process begins at the Collection Site.

  • Driver provides a urine specimen
  • Collector checks the specimen and completes the Federal Custody & Control Form (CCF)
  • Specimen is divided into two bottles:
    • Bottle A — Primary Specimen
    • Bottle B — Split Specimen
  • Both bottles are sealed in the driver's presence
  • Specimen is packaged and shipped to Quest Diagnostics

2. Laboratory Testing

Quest Diagnostics performs the required DOT laboratory testing.

  • Laboratory verifies the specimen seals and CCF information
  • Bottle A (Primary Specimen) is used for laboratory testing
  • If the initial test is Negative, the result is sent to the Medical Review Officer (MRO)
  • If the initial test is Non-Negative, the specimen undergoes confirmation testing
  • Confirmed Non-Negative laboratory results are sent to the MRO for review

3. Medical Review Officer (MRO)

The MRO reviews the laboratory findings and determines the Final Verified Result.

  • Reviews the laboratory findings and CCF documentation
  • Negative results are verified and reported as Negative
  • For a confirmed Non-Negative laboratory result, the MRO contacts the driver when required
  • Driver has an opportunity to provide a legitimate medical explanation
  • Only the MRO can review the driver's prescriptions and medical documentation
  • Negative Results
  • Positive Results
