DOT and workplace drug testing

Workplace drug testing is not clinical lab work with different paperwork. It is a regulated chain that a lawyer may read years later, and every stage of it — who held the specimen, which seal was intact, which cutoff a value was measured against, who certified the result — has to survive that reading. ClinikEHR’s DOT-LIMS module is built around that chain rather than around the result. This section covers the whole lifecycle for a diagnostic centre running Department of Transportation and SAMHSA-regulated testing, and the lighter reference-lab variant for labs that only receive and report.

​

Choose how your lab runs

The module has four shapes, set once by an owner or manager. The card is titled Lab Workflow and explains itself: “Determines which laboratory module is shown to your staff. Switching modes does not delete any data — orders remain in their original workflow.” Choose a mode, then select Save Workflow Mode — Reset puts the card back as you found it. On success you get Lab workflow updated — Reload your DOT-LIMS pages to see the new mode. Reference Lab mode renames the navigation rather than removing it: DOT Testing becomes Lab Intake and DOT History becomes Intake History. The full detail of that mode, including the intake order form, is on Reference lab mode.

​

The lifecycle

In full DOT mode a specimen moves through five stages, each owned by a different person and each writing its own custody event. In Reference Lab mode the first and last stages fall away: the specimen arrives already sealed and already documented, and the finished report goes to an external Medical Review Officer as a PDF.

​

The rule the whole module exists to enforce

Two further rules are enforced for you and worth knowing before you meet them:

• Methamphetamine needs amphetamine alongside it. 49 CFR § 40.97(b)(3): methamphetamine above its cutoff with amphetamine below the linkage threshold cannot be reported as confirmed positive, and ClinikEHR downgrades it to Negative.
• Some drugs can never be verified Negative. 49 CFR § 40.151(f): THC, PCP and 6-acetylmorphine cannot be verified as Negative by the MRO regardless of any prescription or medical explanation the donor provides.

​

Seals and the chain of custody

Every handoff is recorded. The Laboratory Accession card asks for an Accession Number *, a Received Date & Time *, and the condition of both seals — Primary Specimen Seal (Bottle A) * and Split Specimen Seal (Bottle B) * — as Yes/No answers. Answering “no” to either makes Seal Condition Notes * required, and a broken seal raises a confirmation before the order can proceed. Bottle B Storage Location records where the split went, in enough detail that a colleague can retrieve it (“Freezer A-2, Rack 3, Position 7”). The Chain of Custody tab groups every event into Specimen Intake, Laboratory Analysis, Reporting and Post-Report. Each event shows a Seal Intact or Seal Broken pill, the released-by → received-by handoff, any notes, its timestamp and the elapsed time since the previous event. Full detail on Accession an incoming specimen.

The people the module talks about

In drug testing the person tested is the donor, not the patient — that is the word the CCF, the collector and the MRO all use, and it is the word the forms use. Elsewhere in your lab they are patients as usual.
