A workplace positive can end a career. It must be confirmed definitively, with a documented chain of custody.CLIA #45D2048957 · CAP #8722734 · Same-day results · Walk-ins welcome
Three things, and none of them is speed. A documented chain of custody from collection to report. Definitive LC-MS/MS confirmation of every presumptive positive — because immunoassay cross-reactivity is real and a career should not turn on it. And specimen validity testing to detect dilution and adulteration. Federally regulated testing (e.g. DOT) has its own mandatory program requirements, which we will tell you about honestly rather than blur.
The chain
| Stage | Control |
|---|---|
| Collection | Identity verification, tamper-evident seals, documented handoff |
| Transport | Sealed, tracked, signed |
| Screen | Presumptive only — never reported as a final positive |
| Confirmation | LC-MS/MS, quantitative |
| Report | Analyte-specific, with the analytical parameters stated |
A cannabis positive documents exposure, not impairment — the metabolite persists for days to weeks after any effect has ended. Employers regularly misread this, and we say so in writing. See why THC-COOH is not impairment.
Compliance. No payment for referrals, no revenue sharing, no inducements. Testing is performed on the basis of medical necessity and a physician order, at fair market value, consistent with the Anti-Kickback Statute and the Stark Law.
