Laboratory Screening & Confirmation

The best drug testing practices suggest that a presumptive positive result on the initial screen should be confirmed via laboratory confirmation utilizing gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS). The initial screen can done onsite with a rapid test, or the specimen can be collected and sent for a laboratory screen (ELISA/EMIT) which both utilize the same immunoassay technology. The initial screening process for both rapid tests and lab screens are designed to provide only a qualitative preliminary test result. Screening is non-specific which means that it does not differentiate among the drug class.

Confirmation screening utilizes highly complex instrumentation technology which produces a definite or "confirmed" result. The results of a confirmation test provide a definitive final result and differentiates the specific drug compounds present in the urine or oral fluid sample. Confirmations can help clinicians and case workers by providing them critical information about the substances within a patient's system.
