Our Process

How We Test Samples

  • Samples are received at the laboratory from submitting commands via the US Postal Service, private carrier (FEDEX, DHL, UPS) or hand-carried.
  • Once received by the laboratory, samples are processed by the accessioning department in preparation for testing. Strict chain of custody protocol is observed throughout specimen handling and processing.
  • Following processing in accessioning, specimens are transferred to screening to undergo immunoassay testing.
  • If no drug is detected, the service member’s specimen is reported as negative and the member specimen is discarded.
  • If a drug is detected, another specimen is repoured from the original sample bottle and sent for confirmation testing.
  • Specimens sent to confirmation are tested for drug presence and concentration using Gas Chromatography/Mass Spectrometry (GC/MS) or Liquid Chromatography Tandem Mass Spectrometry (LC/MS/MS) instrumentation.
  • Once results are verified by laboratory certifying officials, ensuring all procedures have been followed and results are scientifically valid and legally defensible, the results are uploaded to the iFTDTL web results website.
  • If certified results indicate that a drug is present in a concentration equal to or above the DoD cutoff level, the specimen is reported as positive. If the quantity is below the DoD cutoff level, the sample is reported negative.

Our Commitment To Quality

The Navy Drug Testing Program is committed to providing scientifically valid and legally defensible drug test results in a timely manner to our customers. Submitting unit commanders require accurate and timely results to assess unit readiness and to take swift action on members when an incident of drug abuse has been determined. The Navy Drug Screening Laboratories employ numerous quality control procedures to ensure the integrity of their results. These procedures include:

  • Employee Training and Certification for all Procedures
  • Instrument and Method Validation Procedures
  • Internal Quality Control Samples
  • External Quality Control Samples
  • External Proficiency Samples
  • Multiple layers of data review
  • DoD Inspections - 3 per year at each lab
  • Internal Quality Assurance Audits
