Quantitative LC-MS/MS confirmation, with specimen validity testing and a documented chain of custody.CLIA #45D2048957 · CAP #8722734 · Same-day results · Walk-ins welcome
Four things, and a laboratory should be able to state all four in writing: the analyte list (what is and is not covered), the method (immunoassay screen, LC-MS/MS confirmation, quantitation), specimen validity testing (creatinine, pH, oxidants — detecting dilution and adulteration), and chain of custody documentation. Anything vaguer than that is marketing.
The service, specified
| Component | Detail |
|---|---|
| Screening | Immunoassay, presumptive — what it can and cannot do |
| Confirmation | LC-MS/MS, quantitative — the reference standard |
| Fentanyl | Targeted specifically — standard opiate screens miss it (see this) |
| Specimen validity | Creatinine, pH, oxidizing adulterants |
| Chain of custody | Documented end to end |
| Turnaround | Defined SLA — logistics |
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.
