How long can drugs and metabolites be detected in the system?
The answer to this question will vary based on a variety of factors. Please refer to our Drug Detection Panel Table for details.
What is specimen validity?
We measure creatinine, pH, and specific gravity to determine the validity and potential of adulteration.
Why are screening and confirmation cutoff levels different?
Screening and confirmation testing are performed using different methodologies that necessitate different cutoff levels. The cutoff levels of an immunoassay screen are typically higher than those of a more sensitive GC-MS or LC-MS/MS confirmatory test because they screen for a larger group of parent compounds, metabolites, and other structurally similar compounds.
If an immunoassay test detects a drug (above the screening cutoff level) the presumptive positive specimen may be sent for GC-MS or LC-MS/MS confirmation testing. This testing involves the definitive identification of a specific drug or metabolite. Many times, these individual compounds are present in concentrations much lower than the total immunoassay response, thus the need for lower cutoffs for GC-MS or LC-MS/MS testing.
