When Is Oral Fluid the Right Specimen?

Observed collection, minus the indignity. Substitution becomes very hard.CLIA #45D2048957 · CAP #8722734 · Same-day results · Walk-ins welcome
When recent use is the question, or when collection integrity is the problem. Oral fluid can be collected under direct observation without the invasiveness of observed urine collection, which makes substitution and adulteration substantially harder. Its detection window is shorter and closer to recent use — a feature, not a defect, when that is what you need to know.
Where it fits
| Scenario | Why oral fluid |
|---|---|
| Post-incident | Closer to recent use than urine |
| History of substitution or adulteration | Observed collection is practical |
| Settings where observed urine is unacceptable | Preserves patient dignity |
| Long-window adherence monitoring | Urine is usually better — compare |
Oral fluid does not establish impairment either. No toxicology specimen does. It documents exposure within a window — a clinician determines what that means.
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.
