What Makes a Toxicology Result Defensible?

A number without a quality system behind it is just a number.CLIA #45D2048957 · CAP #8722734 · Same-day results · Walk-ins welcome
The quality system, not the instrument. Calibration curves across the reportable range; quality controls at multiple concentrations in every run; defined limits of detection and quantitation; carryover checks so a very high specimen does not contaminate the next one; internal standards to correct for matrix effects; and external proficiency testing — where an outside body sends blind specimens and grades your answers.
The controls behind the number
| Control | What it guarantees |
|---|---|
| Calibration curve | Quantitation is anchored to known concentrations |
| QC at multiple levels, every run | The run performed as expected — not just the calibrator |
| LOD / LOQ, defined and stated | You know what "negative" actually means |
| Internal standards | Matrix effects and recovery are corrected |
| Carryover assessment | A high positive does not create a false positive downstream |
| Proficiency testing (CAP) | External, blinded verification of accuracy |
| Chain of custody | The specimen is the one you sent |
Ask any laboratory for its LOD and LOQ for the analytes you care about. If they cannot produce them quickly, they are not running a quality system — they are running an instrument.
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.
FAQ
- Are you CAP-accredited?
- Yes — CAP #8722734, CLIA #45D2048957. What that actually requires.
- Will you share your analytical parameters?
- Yes, to clients. That is a normal request and a reasonable one.
- What happens to a failed QC?
- The run is not reported. That is the entire point of the control.
- Who is your laboratory director?
- An MD Laboratory Director, as CLIA requires — registered in the CMS CLIA database under #45D2048957 and independently verifiable.
